Safety information 2.4 Use in hazardous areas
Electrostatic-sensitive devices
NOTICE Electrostatic-sensitive devices The device contains electrostatic-sensitive devices (ESD). ESD can be destroyed by voltages far too low to be detected by humans. These voltages can occur if you simply touch a component part or the electrical connections of a module without being electrostatically discharged. The damage to a module caused by overvoltage cannot normally be detected immediately; it only becomes apparent after a longer period of operating time has elapsed. Protective measures against the discharge of static electricity: · Make sure that no power is applied. · Before working with modules, make sure that you discharge static from your body, for
example by touching a grounded object. · Devices and tools used must be free of static charge. · Hold modules only by their edges. · Do not touch connector pins or conductor tracks on a module with the ESD notice.

Description 3.10 PROFIBUS

3.10

PROFIBUS
The Process Fieldbus (PROFIBUS) is an open communications system for automation technology and is specified in the international standard IEC 61158.
PROFIBUS Process Automation (PROFIBUS PA) is a variant of PROFIBUS Decentral Peripherals (PROFIBUS DP), which is widely used in process technology.

3.10.1

Transmission technology
The PROFBUS PA has the special transmission technique MBP (Manchester coded Bus Powered) and therefore satisfies the requirements of process automation and process engineering requirements.
This transmission technology is defined in the international standard IEC 61158-2.
The PROFIBUS PA is based on the FISCO model (Fieldbus Intrinsically safe Concept) and can therefore be used in hazardous areas.

3.10.2

Bus topology
The bus topology is mainly able to be selected as desired. Therefore, line, star and tree structures, and mixed forms are possible. All types of field devices such as transmitters, actors, analysis devices, etc. can be connected to the PROFIBUS PA.
Advantages include:
Savings on installation costs More extensive diagnostics, leading to increased availability of installation sections Automatic management of installation documentation Installation optimization on the fly during operation In an automation system, there are generally multiple PROFIBUS PA lines connected to fast PROFIBUS DP via coupler units. This is also connected to the process control system.
Both bus systems use the same protocol layer. This makes PROFIBUS PA a "communications-compatible" extension of the PROFIBUS DP into the field.

Operating Instructions, 02/2016, A5E00053276-08

Description 3.10 PROFIBUS

Image 3-12 Functional principle of the PROFIBUS automation system
The figure shows a section of a typical PROFIBUS automation system. The control system consists of two masters with distributed tasks.
The class-1 master recognizes the control and regulation tasks. The class-2 master enables the operating and monitoring functions. Between the class-1 master and the field devices there is a periodic exchange of measurement and settings data. The status information from the field devices is transmitted parallel to this data, and evaluated in the class-1 master. Assignment of parameters for the field devices or the reading of additional device information is not performed during periodic operation.
Besides periodic operation, one or more class-2 masters can access the field devices asynchronously. Using this type of communication, additional information can be retrieved from the devices or settings sent to them.

3.10.3

Properties
PROFIBUS PA allows bidirectional communication between a bus master and field devices. At the same time, the shielded two-strand wiring provides auxiliary power to the two-wire field devices.

4.5.1

Remote seal installation

General installation instructions
Keep the measuring system in the factory packing until it is installed in order to protect it from mechanical damage.
When removing from the factory packing and installing: ensure that damage to and mechanical deformations in the membrane are prevented.
Never loosen the sealed filling screws on the remote seal and the measuring instrument.
Do not cause damage to the remote separating membrane; scratches on the remote separating membrane, e.g. due to sharp-edged objects, are the main starting points for corrosion.
Select suitable gaskets for sealing.
Use a gasket having an adequately large inner diameter for flanging. Insert the gasket concentrically; contact with the membrane leads to deviations in measurements.
When using gaskets made of soft materials or PTFE: follow the guidelines of the gasket manufacturer, especially regarding the tightening torque and setting cycles.
At the time of installation, use suitable fastening components such as screws and nuts that are compliant with fitting and flange standards.
Excessive tightening of screwed joints on the process connection may displace the zero point on the pressure transmitter.
Note Commissioning
If a shut-off valve exists, open the shut-off valve slowly when commissioning in order to avoid pressure surges.
Note Permissible ambient and operating temperatures
Install the pressure measuring device such that the permissible limits of ambient and measured medium temperatures are not overshot or undershot even with the consideration of the effect of convection and heat radiation. · Note the effect of temperature on the measuring accuracy. · When selecting the remote seals, ensure that fittings and flange components have
adequate pressure-temperature resistance by selecting suitable materials and pressure ratings. The pressure rating specified on the remote seal applies to reference conditions according to IEC 60770. · For the maximum permissible pressure at higher temperatures, please refer to the standard specified on the remote seal.

Operating Instructions, 02/2016, A5E00053276-08

Installing / mounting 4.5 "Remote seal" installation
Using remote seals with pressure measuring device for hazardous areas:
When using remote seals with pressure measuring device for hazardous areas, the permissible limits of ambient temperatures for the pressure transmitter must not be exceeded. Hot surfaces on the cooling section (capillaries or cooling elements) are a possible source of ignition. Initiate suitable measures.
When remote seals with a flame arrestor are used, the pressure measuring instrument determines the permissible ambient temperature. In the case of potentially explosive gaseous atmosphere, the temperature around the flame arrestor must not exceed +60 °C.

4.5.2 Notes

Installation of the remote seal with the capillary line
Do not transport the measuring assembly (pressure transmitters, flange and capillary) using the capillary line.
Do not bend capillary lines; risk of leakages and/or risk of considerable increase in the setting time of the measuring system.
Owing to the risk of bending and breakages, pay attention to mechanical overloads at the joints such as capillary line-remote seal and capillary line-measuring device.
Unwinding the excess capillary lines with a radius of at least 150 mm. Fasten the capillary line such that there are no vibrations. Permissible height differences:
When installing the pressure measuring device above the measuring point, keep the following in mind: In the case of remote seal measuring systems with silicon, glycerin or paraffin oil filling, the height difference of H1max. = 7 m must not be exceeded.
If halocarbon oil is used as a fill fluid, this maximum height difference is only H1max. = 4 m; see installation type A and installation type B.
If negative overpressure is observed during measurements, reduce the permissible height difference accordingly.

LO calibration

Introduction

The slope of the characteristic is changed in mode 19. This rotates the characteristic around setting point HI.
This function replaces the zero-point calibration (mode 7) which is not permitted for absolute pressure transmitters.
The unit in which you want to calibrate is set using the following functions:
In mode 13, set the source of the measured value display[7] : Raw pressure value, variable SENS.
In mode 14, select the desired pressure unit.
Note
If you change this setting, the measurement range can be restricted to the point that the permissible sensor limits are violated even with small pressure changes.

Procedure

To calibrate LO, proceed as follows: 1. Set mode 19.
The display shows the value of the last calibration procedure, with the appropriate unit. 2. Create the reference pressure. 3. Press the [] or [] button.
The measured value display switches to the current pressure value. Using the [] and [] keys, you can enter the reference value starting from there. 4. Press the [] und [] buttons simultaneously for 2 seconds. 5. Save with the [M] button.

Operation 6.5 Local operation

Note
In the case of transmitters for absolute pressure, note the following information: · You need a thruster to apply the reference pressure. · The value of the reference pressure can be changed by only about 10%.

Result

If the calibration was successful, the current measurement value of the device will be displayed, and will correspond to the calibration value as long as the reference pressure is still applied.
If you switch to the measured value display without taking a sufficiently large calibration span into account, the pressure status "Bad" B_004 will be displayed.
The failure logic of the function block is activated. The output has the status "Unsure" U_0xx, depending on the setting.
If the two trim points are too close together, status F_006 is displayed. The smallest calibration span depends on the nominal measurement range. Select either the higher reference pressure in mode 20, or the lower reference pressure in mode 19.
As long as mode 19 is active, you can repeat this procedure as often as necessary.

Operator control functions via PROFIBUS 7.1 Communications structure for PROFIBUS PA

Pressure transducer block
The transducer block for pressure handles the adaptation to the pressure sensor. Its output value is the linearized and temperature-compensated measurement result. When measuring levels and flow, the necessary recalculation of the measurement value is performed in the pressure transducer block. The output value is the linearized and temperature-compensated measurement result.
The pressure transducer block also processes the temperature measurement of the pressure sensor and monitors the pressure and temperature limits.

Example

In hydrostatic level measurement, the pressure transducer block converts the incoming pressure value into height or volume.

Electronics temperature transducer block
The electronics temperature transducer block executes the required temperature measurement functions and monitors the permissible temperature limits.

Analog input function block
The analog input function block further processes the selected measurement value and passes it on to the automation task.

Example

For a container full of water, you measure the volume. The analog input function block calculates the container volume [m3] in a user-specific volume unit [bottles]. The output of this block gives the measured value and the corresponding status on the PROFIBUS.

Totalizer function block
The totalizer function block totals the volumes or mass that flowed during flow measurement. Its function is very similar to that of a water meter.
The output of this block forwards the totalized values and the corresponding status information via PROFIBUS.

Local operation and display
The display shows the desired measured value with its physical unit. You can select different functions for local operation.

Functional principle
The raw pressure value first passes through a calibration. The resulting cleaned-up pressure value is checked for sensor limits. Any violation of the limits results in status "Bad" and a diagnostic error of "error collecting measured value". The cleaned-up pressure value is stored in SEC 1.
Then, it is subjected to a normalization, where the input signal is expressed in the range 0 to 10 (percentage/100). The normalized pressure value is stored in SEC 2.
Afterwards, depending on the measurement task, it is fed through one of four different linearization types. Scaling uses the preset working range (minimum and maximum values) to determine the normalized and linearized measured value (pressure, height, or volume) of the actual process variable. This is stored in PRIM.
By means of a multiplication with the density the volume is used to compute the mass. This is stored in SEC 3.
The temperature value of the pressure sensor is available in the "temperature" parameter.

Root extracted and table

Square root extraction of the input value for measurement using the orifice plate method.
With the orifice plate method, the accuracy is greatest when the operating point is at the design point. If there are deviations, the measurement deviation is also greater. For this reason, the measurement accuracy is corrected using a characteristic curve with 31 nodes.

To input a characteristic curve, select the characteristic curve type "user-defined (table)". Enter the "New number of nodes" which you will later want to enter.
The nodes must always be entered in pairs. For each point x[n] in the working range, a point y[n] is required.
The device checks which pair of nodes bracket the pressure (secondary variable 1) relative to the measurement range. To convert the pressure to the measured value (primary variable), the device interpolates on a line between the interpolation nodes.

Electronics temperature transducer block
The electronics temperature transducer block is manufacturer-specific and not described in the profile. The transducer block is responsible for monitoring the internal temperature of the device electronics. The transducer block cannot change the pressure value, only its status.
The permissible limits correspond to those of the permissible ambient temperature. If a limit is violated, the status changes to "GOOD Active Critical Alarm High/Low-limit". The status of the cleaned-up pressure value in the pressure transducer block receives the status "UNCERTAIN Value not accurate high/low-limit". This procedure is accompanied by a PROFIBUS diagnostic message "Electronics temperature too high".
There are also peak indicators for maximum and minimum values available.

Analog input function block
The analog input function block is part of the standard functions of pressure transmitters. The following figure shows the processing of the measured values up to the output.

Mi Incoming measured value from the transducer for pressure
OUT Output (value, status)

MAN Manual O/S Out of Service AUTO Automatically

Operating principle
The incoming measurement value from the pressure transducer block - or a simulated value prescribed through the simulation switch - is subject to another normalization (measured value scaling) and a projection onto the output range through output scaling (applicationspecific measured value).
Afterwards, the signal is filtered (damping) and check for being within preset limit values. An upper and lower warning and alarm limit is always available.
If the measured value has the status "Bad", the shutdown logic can output a safety preset value: This may be the last usable measured value or a preset substitute value.

Using the target mode selected in Mode and status processing, you can choose between output of the automatically acquired measured value (AUTO setting) or a manually set simulation value (MAN setting). If the function block is out of order (O/S setting) then the safety preset value is always output. The analog input function block handles the numerical value separately from the physical unit. This allows you to set 1000 predefined units.

OUT Output (value, status)

AUTO Automatically

Operating principle
The function block processes the measured values from the transducer for pressure. If the status of the measured values is "bad", the setting of the failure behavior decides whether this value or the last "good" value is forwarded for totalizing.
The measured value now pass through the specified summation direction. The measured values are fed to a forward flow, reverse flow or net counting function.
The measured values are then integrated over time so that the flow can be calculated for a specified time segment. Adherence to the limit values is also checked. Here, it is also possible to reset the counted total to a preload value.
You can reset or initialize the totalizer function block not only with acyclic services. You can configure the totalizer function block so that you can reset or initialize it from the user program in cyclic data traffic.
In the Mode and status processing, select Target mode. Using the target mode, you can choose between output of the automatically acquired measured value (AUTO setting) or a manually set simulation value (MAN setting).
The possible units correspond to the volume and mass values of the transducer for pressure.

Application point of the root function, creep quantity suppression
If you want to suppress the error that occurs at low flow quantities, you have two options that you can also combine:
The application point of the root function determines the point below which the root function becomes linear.
Creep quantity suppression sets the measured flow quantity to 0, when the value falls below the preset limit.
Enter the application point as a % of the operating range (volume flow).

Adjusting to a desired process value
The analog input function block has the purpose of mapping the measured value to the process value. In general, you want to direct the measured value straight to the bus: Then the input and output range is taken from the working range.
If the measured pressure or the fill level has an indirect but linear relation to the process value, however, assign the start and final values of the input range to start and final values for the output range. The following examples illustrate this:

The procedure is shown by means of two concrete application examples.

If the output variables of the transducer block have the status "Bad" due to an error, activate the failure behavior for the function blocks. The status "Unsure" then accompanies the output or the totalizer output.

Min/max indicator

Description

The pressure transmitter has three pairs of min/max pointers which you can use to monitor the three measured variables pressure, sensor temperature, and electronics temperature for negative and positive peak values. For each measured value, a resettable min/max pointer saves the maximum and minimum peak values in long-term storage in the two non-volatile memories. Consequently, the values are available even after the device is restarted. The min/max pointers are also updated during a simulation.

From the output of the pressure transmitter, you can get ever closer to the sensor and check the measurement and function blocks. The display indicates active simulation with an "Si" in the mode display.

7.10.2

Simulating output
By simulating the output, you can make process values available at the output of the pressure transmitter for cyclic data transmissions using acyclic write access. This allows you to test the process value processing in the automation program.

Procedure

To simulate the output, make the following settings: 1. Select output simulation. 2. Set the target mode to manual (MAN). 3. Enter the desired output value, the quality, and the status. 4. Transmit the settings from the program into the pressure transmitter. The behavior of the output can be observed, e.g. in SIMATIC PDM or using a variable table (VAT component). To return to normal operation afterwards, set the target mode to AUTO.

The behavior of the measured value (primary variable), the secondary variables 1, 2, and 3, and of the output, can be observed in SIMATIC PDM. To return to normal operation afterwards, you must switch off the simulation.

7.10.5

Simulating sensor and electronics temperature
By simulating the sensor and electronics temperature you can, for instance, check the influence of excessive temperature on the measurement results:

Procedure

To simulate the sensor and electronics temperature, make the following settings: 1. Select the simulation of sensor or of the electronics temperature. 2. Set the simulation mode and the parameters:
Simulation mode "Fixed" and parameter pressure value Simulation mode "Ramp" and ramp parameters 3. Transmit the settings from the program into the pressure transmitter. The behavior of the measured value (primary variable), the secondary variables 1, 2, and 3, and of the output, can be observed in SIMATIC PDM. To return to normal operation afterwards, you must switch off the simulation.

7.11

Calibrating the sensor
Sensor calibration enables you to calibrate the pressure transmitter. Analogous to modes 19 and 20 for local operation, you can change the slope of the characteristic curve of the pressure transmitter.
Using a lower and an upper trim point, you can determine the course of the characteristic curve.
Change the slope of the characteristic to a minimum of 0.9 and a maximum of 1.1. Any larger variation from a slope of 1.0 will prevent the respective trim point from being stored.
The lower trim point must be far enough from the upper trim point so that the smallest calibration span is included.
The smallest calibration span is displayed in the sensor calibration dialog and depends on the measurement range. If the calibration is smaller than the smallest span, the following status code accompanies the measured value:
"Bad, configuration error"
In this case, recalibration the lower or the upper sensor trim point with a sufficiently large calibration span.

Operator control functions via PROFIBUS 7.12 Correcting for positional error

Calibrating the lower point
To calibrate the lower point, proceed as follows: 1. Call up the dialog "Sensor Trim". 2. Apply the reference pressure for the lower sensor trim point. 3. Enter the value of the reference pressure in the field "Lower Sensor Trim Point". 4. Click on "Transfer". In the field "Pressure cleaned raw value", observe the effect of the calibration. In the "Lower Sensor Trim Point" box, you can see whether the new trim point was applied.

Calibrating the upper point
To calibrate the upper point, proceed as follows:
1. Call up the dialog "Sensor Trim".
2. Switch to the "Upper Sensor Trim" tab.
3. Apply the reference pressure for the upper sensor trim point.
4. Enter the value of the reference pressure in the field "upper sensor trim point".
5. Click on "Transfer".
In the field "Pressure cleaned raw value", observe the effect of the calibration. In the "Upper Sensor Trim Point" box, you can see whether the new calibration point was applied.
After both points have been calibrated, the status of the measured value must be "Good". If the status "Bad, configuration error" is displayed, the calibration was smaller than the smallest calibration span. You must move the trim points away from one another by moving one of the two trim points.

Resetting to delivery state
If the pressure transmitter is so maladjusted that it can no longer fulfill its measurement tasks, you can use this function to reset it to the factory settings. It resets all parameters to the factory settings, with a few exceptions.
The exceptions are:
PROFIBUS address Device operation type Static version number
In Transducer Block 1
In the analog input function block
The reset is indicated by the diagnostic message "New start executed". The automation or control system reads the status "Unsure, initial value, value constant" until a measured value result is available.

7.13.2

Warm start/restart
With a warm start, you cause the pressure transmitter to switch itself off and restart. This interrupts and then reestablishes communication.
You need this function, for example, if the PROFIBUS address is changed during running communication with a cyclical master.
This restart is indicated by the diagnostic message "Restart executed". The automation or control system reads the status "Unsure, initial value, value constant" until a measured value result is available.

7.13.3

Resetting the PROFIBUS address
If no other pressure sensor in your system has the preset address 126, you can add your pressure transmitter to the PROFIBUS strand during running operation of the automation or control system. You must subsequently change the address of the newly connected device to a different value.
If you remove the pressure transmitter from the PROFIBUS chain, reset its address to 126. This allows you to include the pressure transmitter in this or another system if necessary.

Functional safety

8.1

Safety function
The safety function of SITRANS P DS III with PROFIsafe protocol (ordering option -Z C21) is based on the measurement of pressure.
The pressure is converted to a digital measured value and transmitted via PROFIsafe communication. Fault tolerance allowances must be made, because the measured value transferred to the automation system by the pressure transmitter can deviate from the physical value. This fault tolerance is calculated as follows:
Total tolerance (safety function) = ± [application-specific measurement error + 2 % safety accuracy].
Pressure transmitter safety accuracy: the maximum effect of a non-critical individual error on the measured value.
The measured value is transferred along with the "Validity" and "Quality" status information.
The diagnostics function will respond within 60 seconds in the worst-case scenario.
The safety accuracy together with the application-specific measurement error allows the system operator to include a backup for process monitoring. Even if a random individual error occurs that is within the safety accuracy, the system can still be safely shut down.
As there is also always a possibility of dangerous faults occurring, these are categorized and listed in the manufacturer declaration for the device (SIL declaration of conformity, functional safety pursuant to IEC 61508 and IEC 61511).
Example:
A silo is to be securely monitored to check that the level does not exceed 10 meters.
Application-specific measurement error: 0.1% Safety accuracy: 2.0% Total tolerance: 2.1% 2.1% of 10 meters is 21 centimeters. If process monitoring is set to 9.79 meters, safe shutdown is guaranteed even in the event of a random individual error within the safety accuracy.
Note Use of remote seals
If remote seals are used, the application-specific measurement error is the product of the pressure transmitter and remote seal measurement errors.

Functional safety 8.2 Safety Integrity Level (SIL)
WARNING Disregarding conditions for fulfilling the safety function Disregard can result in a malfunction of the process plant or application, e.g. process pressure too high, maximum level exceeded. The mandatory settings and conditions are listed in chapters "Settings (Page 132)" and "Safety-related characteristics (Page 132)". Please observe the applicable conditions to ensure the safety function.
Safety-instrumented system in single-channel operation (SIL 2)

Image 8-1 Safety-related system for pressure transmitters in single-channel operation
The combination of pressure transmitter, automation system and final controlling element forms a safety-instrumented system that performs a safety function. The emphasis of this description is on the pressure transmitter. For information on requirements for the automation system or final controlling element, please refer to the corresponding standards.
The pressure transmitter generates a process-related measured value that is transferred to the automation system. The automation system monitors this measured value. If the measured value violates the high or low limit, the automation system generates a shutdown signal for the connected final controlling element, which switches the corresponding valve to the specified safety position.
Only one SITRANS P DS III device is required for single-channel operation for SIL 2.

8.2

Safety Integrity Level (SIL)

The international standard IEC 61508 defines four discrete Safety Integrity Levels (SIL) from SIL 1 to SIL 4. Every level corresponds to a probability range for the failure of a safety function.

Overview

Checking safety
Check the safety function of the entire safety circuit on a regular basis in accordance with IEC 61508/61511. The test intervals are determined in the course of calculations for each safety circuit of a system (PFDAVG).
Checking safety function/proof test
Runs this test to detect hidden serious faults of the pressure transmitter. Hidden faults result in incorrect measurements and dangerous failures in your safety-related system. If necessary, replace the pressure transmitter.

Enabling write protection
After parameter assignment/commissioning as well as after a proof test, perform the following steps:
1. Disable the write protection. For this purpose you have various options, which are described in the section "Write protection (Page 150)".
2. Protect the keys from unintended change in the parameters, e.g. by selecting the key lock or function lock (Mode 10).

Electronics and measuring cell
The safety function of the pressure transmitter is ensured only if you use the electronics, measuring cell, display and connection board delivered by the factory. These components cannot be replaced.

PROFIsafe

8.7.1

Introduction
PROFIsafe enables safe communication by detecting and reporting all communication errors. Data security is continuously monitored on the PROFIBUS in the process.

8.7.2

Technical advantages of PROFIsafe
The main advantage of PROFIsafe is that the PROFIBUS communication channel becomes secured by a protocol in a transparent way. Thus incorrect values cannot be transferred to the master without being discovered. The user does not need any special network components. All the user needs is the standard network components of PROFIBUS. However, the CPU must be suitable for safety applications.
In the following example, you see that PROFIsafe and PROFIBUS devices can be operated simultaneously on a PROFIBUS network.

Cyclical data transfer

Cyclical data transmission is used to transfer user data relevant for process automation between the control or automation system (class 1 master) and the pressure transmitter.

Setting the PROFIBUS address
The PROFIBUS is set to 126 at the factory. You set it at the device or using a parameterization tool through the bus, e.g.:
SIMATIC PDM HW Config The new address will take effect either after the first warm start or when the device is disconnected temporarily from the bus.

9.2

Configuring

9.2.1

Overview of configuration

General

Information on the input and output range as well as the consistency of cyclically transmitted data is defined in the device master data file (GSD file). Using the configuration packet, it is checked by the device and declared valid. During projection it must be determined which data will be transmitted in cyclical operation. This allows the optimization of the data quantity to be transmitted. In the Siemens control system, the GSD files of all the usual devices are already available, and they are also available on the Internet and can be imported later.

Configuration of user data
The user data which are provided through the PROFIBUS to the control system are based on the selected target configuration. User data is generated by the function blocks and assembled in the following order:

Diagnosis
Besides status information, the device can also actively send information about its own state. Diagnostics are important information which an automation system can use to initiate corrective measures.
To transmit diagnostic information, the standard mechanisms of the PROFIBUS DP are used and messages are actively sent to the class 1 master. PROFIBUS DP provides a protocol to transmit information to the class 1 master with a higher priority than the user data.

Messages

The content of the "Device state" parameter from the physical block is sent, along with information about whether a state change (event incoming/event sent) has occurred.
The diagnostic object consists of four bytes. For the pressure transmitter, only the first two bytes are relevant.

Configuration/project engineering 9.3 Acyclic data transfer

Note
The device state can be simulated using SIMATIC PDM. This allows you to check the reaction of the automation system to an error.

9.3

Acyclic data transfer

Acyclic data transmission is used primarily for the transmission of parameters:

During commissioning
During service
In batch processes
To display additional measurement data which is not sent during cyclic user data transmission, e.g. raw pressure value

The data traffic between a class 2 master and the field device occurs over a so-called C2 connection. So that multiple class 2 masters can access the same pressure transmitter at the same time, the device supports up to four C2 connections. However, you must ensure that the same data is not being written.

Basic safety instructions
DANGER Toxic gases and liquids Danger of poisoning when venting the device: if toxic process media are measured, toxic gases and liquids can be released. · Before venting ensure that there are no toxic gases or liquids in the device, or take the
appropriate safety measures.
WARNING Improper commissioning in hazardous areas Device failure or danger of explosion in hazardous areas. · Do not commission the device until it has been mounted completely and connected in
accordance with the information in Chapter "Technical data (Page 193)". · Before commissioning take the effect on other devices in the system into account.
WARNING Opening device in energized state Danger of explosion in areas subject to explosion hazard. · Only open the device in a de-energized state. · Check prior to commissioning that the cover, cover locks, and cable inlets are

10.2

Introduction to commissioning
Following commissioning, the pressure transmitter is immediately ready for use.
To obtain stable measured values, the pressure transmitter needs to be allowed to warm up for around 5 minutes after the power supply is switched on. When it starts up, the pressure transmitter goes through an initialization routine (display at the end: "Init done"). If the pressure transmitter does not complete the initialization routine, check the auxiliary power.

NOTICE Electrostatic-sensitive devices The device contains electrostatic-sensitive devices (ESD). ESD can be destroyed by voltages far too low to be detected by humans. These voltages can occur if you simply touch a component part or the electrical connections of a module without being electrostatically discharged. The damage to a module caused by overvoltage cannot normally be detected immediately; it only becomes apparent after a longer period of operating time has elapsed. Protective measures against the discharge of static electricity: · Make sure that no power is applied. · Before working with modules, make sure that you discharge static from your body, for
example by touching a grounded object. · Devices and tools used must be free of static charge. · Hold modules only by their edges. · Do not touch connector pins or conductor tracks on a module with the ESD notice.

Changing the measuring cell and application electronics
Each of the individual components "Measuring cell" and "Electronics" has a non-volatile memory (EEPROM).
Measuring cell data (e.g.: measuring range, measuring cell material, oil filling) and application-specific electronics data (e.g.: downscaling, additional electrical damping) are located in the measuring cell EEPROM. Application-specific data is lost when the measuring cell is changed. Application-specific data is not lost when the application electronics is changed.
You can backup application-specific data before changing the measuring cell and reload it afterwards. Use an input device which supports the PROFIBUS protocol (e.g. PROFIBUS communicator, PC with PROFIBUS modem and PROFIBUS software or PC with PROFIBUS modem and PDM software). Factory settings will be used if application-specific data is not backed up before the measuring cell is changed.
Technical developments enable advanced functions to be implemented in the firmware of the measuring cell or application electronics. Further technical developments are indicated by modified firmware statuses (FW). The firmware status does not affect whether the modules can be replaced. However, the scope of functions is limited to the function of existing components.
If a combination of certain firmware versions of measuring cell and application electronics is not possible for technical reasons, the device will identify this problem and go into "Fault current" mode. This information is also provided over the PROFIBUS interface.

Safety Integrity Level
Safety Instrumented System

Meaning
Software package for graphical, technology-oriented configuration of automation tasks
Frequency of failure Number of faults withing 109 hours
Hardware fault tolerance:
Capability of a function unit to continue executing a required function in the presence of faults or deviations.
Classification and description of the safety-instrumented system in terms of redundancy and the selection procedures used.
A safety-instrumented system or part that consists of "N" independent channels. The channels are connected to each other in such a way that "M" channels are in each case sufficient for the device to perform the safety instrumented function.
Example: Pressure measurement: 1oo2 architecture. A safetyinstrumented system decides that a specified pressure limit has been exceeded if one out of two pressure sensors reaches this limit. In a 1oo1 architecture, there is only one pressure sensor.
Average period between two failures
Average period between the occurrence of a fault in a device or system and restoration of functionality
Probability of dangerous failures of a safety function on demand
Average probability of dangerous failures of a safety function on demand
Proportion of safe failures:
Proportion of failures without the potential to bring the safetyinstrumented system into a dangerous or non-permissible functional status.
The international standard IEC 61508 defines four discrete Safety Integrity Levels (SIL 1 to SIL 4). Each level corresponds to a range of probability for failure of a safety function. The higher the Safety Integrity Level of the safety-instrumented system, the lower the probability that it will not execute the required safety functions.
A safety-instrumented system (SIS) executes the safety functions that are required to achieve or maintain a safe status in a system. It consists of a sensor, logic unit/control system and final controlling element.

Glossary

Coupler

connects the DP and PA segments in PROFIBUS. It has a fixed transmission speed. The transmission speed is 45.45 kbps (DP) to 31.25 kbps (PA).

Dangerous failure
Failure with the potential to switch a safety-instrumented system to a hazardous or nonfunctioning safety status.

Diameter nominal
The diameter nominal is specified according to DIN EN ISO 6708 by the term DN followed by a dimensionless number approximating the inner diameter in millimeters. According to DIN 2440 (medium-weight threaded pipe), a DN 50 pipe, for example, identifies a pipe with an outer diameter of 60.3 mm and a wall thickness of 3.65 mm (inner diameter therefore 53 mm).

EEPROM

EEPROM (Electrically Erasable Programmable Read-Only Memory) is a non-volatile, electronic memory chip.
EEPROM are often used when individual data bytes change over long intervals and need to be stored and retained if there is a network failure, for example configuration data or operating hours counters.

Failure/Fault

Failure: A resource is no longer capable of executing a required function.
Fault: Undesired state of a resource indicated by the incapability of executing a required function.

Fault

Failure/Fault

Fault tolerance
Fault tolerance N means that a device can execute the intended task even when N faults exist. The device fails to execute the intended function in the case of N+1 faults.

Glossary

Final controlling element
Converter that converts electric signals into mechanical or other non-electric variables.

Firmware

Firmware is a type of software that is embedded in a chip in electronic devices in contrast to software proper that is stored on hard disks or other media. Today, firmware is usually stored in a flash memory or EEPROM.
The firmware usually contains elementary functions for controlling the device or input and output routines.

Frequency shift keying
Frequency shift keying is a simple modulation method in which the digital values 0 and 1 are represented by two different frequencies.

Frequency shift keying (FSK) Frequency shift keying

Function block

A named block consisting of one or more inputs, outputs, and included parameters.
Function blocks represent the basic automation functions executed by an application in a way as independent as possible from the details of I/O devices and the network. Each function block processes input parameters using a specified algorithm and a set of internally stored parameters. They produce output parameters which are available for use inside the same function block application or by other function block applications.

Generic Station Description
The generic station description (GSD) contains the information necessary for the control system to establish communication.

Glossary

Risk

Combination of the probability of damage occurring and the extent of the damage.

Safety function
Defined function executed by a safety-instrumented system with the objective of attaining or maintaining a safe status of the system by taking a defined hazardous incident into account.
Example: Limit pressure monitoring

Safety Integrity Level SIL

Safety-instrumented system
A safety-instrumented system (SIS) executes the safety functions that are required to achieve or maintain a safe status in a system. It consists of a sensor, logic unit/control system and final controlling element.
Example: A safety-instrumented system is made up of a pressure transmitter, a limit signal sensor and a control valve.

Sensor

Converter that converts mechanical or other non-electric variables into electric signals.

SIL
The international standard IEC 61508 defines four discrete safety integrity levels (SIL) from SIL 1 to SIL 4. Every level corresponds to a probability range for the failure of a safety function. The higher the SIL of the safety-instrumented system, the higher the probability that the required safety function works.
The achievable SIL is determined by the following safety-instrumented characteristics:
Average probability of failure on demand (PFDAVG) Hardware fault tolerance (HFT) Safe failure fraction (SFF)

Glossary

srlin2

"srli2" or "srlin2" is a type of square root extracting characteristic curve for the output current. This characteristic curve type is proportional to the flow rate, linear in two levels up to the application point and has a pre-defined application point of 10%.
"srli2" or "srlin2" are synonymous and technically there is no difference between them. The abbreviation "srli2" is used in sections that refer to the on-site operation of the pressure transmitter. The reason for the abbreviation is that the pressure transmitter display is restricted to five characters. The abbreviation "srlin2" is used for HART operation.

Zero point adjustment
After the following functions, the measuring range will have changed: Zero point calibration LO calibration HI calibration If you have used one of these functions, the measuring range will have changed. This changed, remaining measuring range is called the zero point offset. Refer to the Operation section for the corresponding modes of these functions.
