Parameters/address space 4.2 Explanation of parameters
Parameters of the sensor supply
Short-circuit test
Here you activate the short-circuit detection for the channels of the F-module for which an internal sensor supply is set. The short-circuit test can always be performed when you use simple switches which do not have an own power supply. For switches with an own power supply, e.g. 3-/4-wire proximity switches or optical sensors with OSSD outputs (Output Signal Switching Device), you have to adjust the parameter "Startup time of sensor after short-circuit test" depending on the sensor used. The short-circuit detection switches off the sensor supply briefly. The length of the deactivation period is equivalent to the configured "Time for short-circuit test". If a short-circuit is detected, the F-module triggers a diagnostic interrupt and the input is passivated. The following short-circuits are detected: · Short-circuit of input to L+ · Short-circuit of the input with another channel, if this has a 1-signal · Short-circuit between the input and sensor supply of another channel · Short-circuit between the sensor supply and the sensor supply of another channel If the short-circuit test is disabled, you must make your wiring short-circuit and cross-circuit proof or select a connection type (discrepancy, non-equivalent) which also detect the crosscircuits using discrepancy.
Note During the execution time (Time for short-circuit test + Startup time of sensor after shortcircuit test) of the short-circuit test, the last valid value of the input before the start of the short-circuit test is passed to the F-CPU. The activation of the short-circuit test thus affects the response time of the respective channel or channel pair.
Note Safety mat evaluation If you have configured "Safety mat evaluation" for a channel pair under "Sensor evaluation", short-circuit tests are performed on the internal sensor supplies that were assigned to this channel pair. These short-circuit tests are performed with a defined test pattern. The parameters "Time for short-circuit test" and "Startup time of sensor after short-circuit test" cannot be changed.

Parameters/address space 4.2 Explanation of parameters

4.2.2.2

Time for short-circuit test

Function

When the short-circuit test is enabled, the corresponding sensor supply is switched off for the configured time. If the module does not detect a "0" signal at the input within the assigned time, a diagnostic message is generated.
Note the following during parameter assignment:
· If the channel is passivated, this may be due to too high capacitance between sensor supply and input. This consists of the capacitance per unit length of the cable and the capacitance of the employed sensor. If the connected capacitance does not discharge within the assigned time, you need to adjust the "Time for short-circuit test" parameter.
· The values available for the input delay depend on the "Startup time of sensor after shortcircuit test" and the "Time for short-circuit test" of the configured sensor supply.

Requirement

The short-circuit test is activated.

Safety mat evaluation
If you have configured "Safety mat evaluation" for a channel pair under "Sensor evaluation", short-circuit tests are performed on the internal sensor supplies that were assigned to this channel pair. These short-circuit tests are performed with a defined test pattern. The parameters "Time for short-circuit test" and "Startup time of sensor after short-circuit test" cannot be changed.

Parameters/address space 4.2 Explanation of parameters

4.2.2.3

Startup time of sensor after short-circuit test

Function

Apart from the switch-off time ("Time for short-circuit test"), a startup time must also be specified for the execution of the short-circuit test. With this parameter you inform the module how long the used sensor requires for the startup after the sensor supply is switched on. This way you avoid an undefined input status due to transient responses in the sensor.
Note the following during parameter assignment:
· This parameter must be larger than the settling time of the sensor used.
· Since the parameterized time affects the response time of the module, we recommend setting this time as short as possible but large enough so that the sensor has stabilized.
· The values available for the input delay depend on the "Startup time of sensor after shortcircuit test" and the "Time for short-circuit test" of the configured sensor supply.

Requirement

The short-circuit test is activated.

Note
Dependencies between the parameters "Startup time of sensor after short-circuit test" and "Time for short-circuit test"
The startup time of the sensor after the short-circuit test must amount to at least 1 % of the time for the short-circuit test.

Note
Safety mat evaluation
If you have configured "Safety mat evaluation" for a channel pair under "Sensor evaluation", short-circuit tests are performed on the internal sensor supplies that were assigned to this channel pair.

4.2.3.1

Sensor evaluation

Overview

Select the type of sensor evaluation with the "Sensor evaluation" parameter: · 1oo1 evaluation · 1oo2 evaluation, equivalent · 1oo2 evaluation, non-equivalent · Safety mat evaluation

1oo1 evaluation
The sensor uses only one input channel for the 1oo1 evaluation.

1oo2 evaluation, equivalent/non-equivalent
With a 1oo2 evaluation equivalent/non-equivalent, two input channels are occupied by: · One two-channel sensor · Two one-channel sensors · One non-equivalent sensor The input signals are compared internally for equivalence or non equivalence. Note that in 1oo2 evaluation, two channels are combined into a channel pair. The number of available process signals of the F-module is reduced accordingly.

Discrepancy analysis
When using a two-channel sensor or two one-channel sensors which measure the same process variable, the sensors interact with a slight time delay due to the limited precision of their arrangement.
The discrepancy analysis for equivalence/non equivalence is used for fail-safe applications to prevent errors from time differences between two signals for the same function. The discrepancy analysis is initiated when different levels are detected in two associated input signals (when testing for non equivalence: the same levels). A check is made to determine whether the difference in levels (when testing for non equivalence: the same levels) has disappeared after an assignable time period, the so-called discrepancy time. If not, this means that a discrepancy error exists.

Equipment Manual, 04/2022, A5E50578307-AB

Parameters/address space 4.2 Explanation of parameters

Safety mat evaluation
With safety mat evaluation, two input channels and two internal sensor supplies are occupied by a 4-wire safety mat (NO contact operating principle). If necessary, you can also connect several 4-wire safety mats connected in series.

4.2.3.2

Discrepancy behavior

Function

For the "Discrepancy behavior", you assign the value that is supplied to the safety program in the F-CPU during a discrepancy between two relevant input channels, which means while discrepancy time is running. You assign the discrepancy behavior as follows:
· "Supply last valid value"
· "Supply value 0"

Requirements

You have assigned the following: · "Sensor evaluation": "1oo2 evaluation, equivalent" or "1oo2 evaluation, non-equivalent"

"Supply last valid value"
The most recent valid value (old value) before the discrepancy occurred is made available to the safety program in the F-CPU as soon as a discrepancy is detected between the signals of the two affected input channels. This value is supplied until the discrepancy disappears or the discrepancy time expires and a discrepancy error is detected. The sensor-actuator response time is correspondingly increased by this time.
This means the discrepancy time of connected sensors with 1oo2 evaluation must be adjusted to short response times. It makes no sense, for example, if connected sensors with a discrepancy time of 500 ms trigger a time-critical shutdown. In the worst possible case, the sensor-actuator response time is extended by the discrepancy time:
· For this reason, position the sensors in the process in such a way as to minimize discrepancy.
· Then select the shortest possible discrepancy time which is also sufficient to compensate for faulty triggering of discrepancy errors.

"Supply value 0"
As soon as a discrepancy between the signals of the two relevant input channels is detected, the value "0" is made available to the safety program in the F-CPU.
If you have set "Supply value 0", the sensor-actuator response time is not affected by the discrepancy time.

Parameters/address space 4.2 Explanation of parameters

4.2.3.3

Discrepancy time

Function

You can set the discrepancy time for each channel pair.

Requirements

You have assigned the following:
· "Sensor evaluation": "1oo2 evaluation, equivalent" or "1oo2 evaluation, non-equivalent"
In most cases, a discrepancy time is started, but does not fully expire because the signal differences are cleared within a short time.
Set the discrepancy time high enough that in the error-free case the difference between the two signals (when testing for non equivalence: the same levels) has always disappeared before the discrepancy time has expired.

Behavior while discrepancy time is running
While the programmed discrepancy time is running internally on the module, either the last valid value or "0" is returned to the safety program on the F-CPU by the input channels involved, depending on the parameter settings for the behavior at discrepancy.

Behavior after expiration of the discrepancy time
If no agreement (when checking for non equivalence: inequality) of the input signals exists once the assigned discrepancy time expires, for example, due to a break in a sensor wire, a discrepancy error is detected and the "Discrepancy error" diagnostic message containing information on which channels are faulty is generated.
Note Dependencies between the parameters "Discrepancy time" und "Input delay" The discrepancy time must be parameterized greater than the input delay.

4.2.3.4

Reintegration after discrepancy error

Function

This parameter specifies the criteria for when a discrepancy error is regarded as corrected, thus enabling reintegration of the relevant input channels. The following parameter assignment options are available:
· "Test 0-Signal necessary"
· "Test 0-Signal not necessary"

Requirements

You have assigned the following: · "Sensor evaluation": "1oo2 evaluation, equivalent" or "1oo2 evaluation, non-equivalent"

"Test 0-Signal necessary"
If you have assigned "Test 0-Signal necessary", a discrepancy error is not regarded as corrected until a 0-signal is present at both of the relevant input channels.
If you are using non equivalent sensors, which means you have set "Sensor evaluation" to "1oo2 evaluation, non-equivalent", the result of the channel pair must be "0" again.

"Test 0-Signal not necessary"
If you have assigned "Test 0-Signal not necessary", a discrepancy error is regarded as corrected when a discrepancy no longer exists at both of the relevant input channels.

Channel failure acknowledge
Use on S7-1200/1500 F-CPUs
The parameter is only relevant if the F-module is operated on an S7-1200/1500 F-CPU.
The parameter can only be set if the F-parameter "Behavior after channel fault" is set to "Passivate channel" and the F-parameter "Reintegration after channel fault" is set to "Adjustable".
The value of this parameter specifies how the channel reacts after a channel fault:
· Manual: A channel failure is reintegrated after manual acknowledgment.
· Automatically: The channel is reintegrated automatically after a channel fault. Manual acknowledgment is not necessary.
Use on S7-300/400 F-CPUs
The value of this parameter is not relevant in the case of operation on S7-300/400 F-CPUs. For S7-300/400 F-CPUs you set the corresponding property at the F-I/O DB by means of the ACK_NEC tag.

Input delay

Function

To suppress injected interference, you can set an input delay for a channel or a channel pair.
Interference pulses whose pulse time is less than the set input delay are suppressed. Suppressed interference pulse are not visible in the safety program.
A high input delay suppresses longer interference pulses, but results in a longer response time.
The set value for the input delay has to be smaller than the configured "Startup time of sensor after short-circuit test" and smaller than the configured "Time for short-circuit test".
With 1oo2 evaluation, the input delay of the lower-order channel (channel n) automatically applies to the higher-order channel (channel n+4).
Note Input delay with Safety mat evaluation
If the Safety mat evaluation is set, you must configure an input delay of 1.6 ms.
Note
Due to the physical properties, there is a possibility of crosstalk between signals in the case of long, unshielded signal lines (see section "Electromagnetic compatibility" in the system manual ET 200SP distributed I/O system (https://support.industry.siemens.com/cs/ww/en/view/58649293)).
Adapt the input delay or use shielded signal lines in order to prevent possible passivation of the fail-safe digital inputs and switch-off of the sensor supply.

Chatter monitoring

Function

Chatter monitoring is a process control function for digital input signals. It detects and reports unusual signal sequences in the process with 1oo1 evaluation, for example, an input signal fluctuating between "0" and "1" too frequently. The occurrence of such signal characteristics is an indication of faulty sensors or process control instability.

Recognizing unusual signal patterns
An assigned monitoring window is available for each input channel. The monitoring window starts with the first signal change of the input signal. If the input signal changes within the monitoring window at least as often as the assigned "Number of signal changes", a chatter error is detected. If no chatter error is detected within the monitoring window, the next signal change restarts the monitoring window.
If a chatter error is detected, a diagnostic is signaled. If the chatter error does not occur for the monitoring window for three times the configured period, the diagnostic is reset.

Principle

The figure below shows the principle of chatter monitoring as a graphic.

Assigning inputs to each other
The digital input module F-DI 8×24VDC HF has 8 fail-safe inputs, DI0 to DI7 (SIL3). You can combine two of these inputs to one input. You can combine the following inputs: · DI0 with DI4 · DI1 with DI5 · DI2 with DI6 · DI3 with DI7 The process signals are provided by channels DI0,DI1,DI2 and DI3.

Wiring

The wiring is performed on a suitable BaseUnit.

Sensor supply

For application 3.1, the sensor supply must be set up for at least one channel internally with activated short-circuit test.
The sensor can be supplied internally or externally for application 3.2.

Requirements for applications in machinery protection with Cat.4
Both conditions must be met for applications in machine protection with Cat.4:
· The wiring between sensors and automation system and between automation system and actuators must be designed to state-of-the-art engineering and standards to prevent short-circuits.
· The actuators must be wired as seen in sections Application 3.1: Safety mode SIL3/Cat.4/PLe (Page 46) or Application 3.2: Safety mode SIL3/Cat.4/PLe (Page 49). You only need to detect one short-circuit because two faults are required to generate it. This means both signal cables in short-circuit have an isolation fault. A multiple short-circuit analysis is not required.
Procedures for locating all short-circuits are also permitted if single short-circuits are not located. One of the two conditions must be met for this purpose:
· Short-circuits may not corrupt the read signals compared to the sensor signals.
· Short-circuits cause a corruption of the read signals compared to sensor signals in the direction that ensures safety.

WARNING You may only use 4-wire safety mats with a current-carrying capacity of at least 100 mA.
WARNING If a short-circuit of the sensor supply to ground occurs, you must check after resolving the short-circuit whether the safety mat is functional by activating it. An excessive current load may damage the contact of the safety mat.
WARNING When selecting the cables and safety mats, note that the ohmic resistance of the cables including an activated safety mat must not exceed 100 ohms.

Determining the ohmic resistance for connecting a safety mat
If you do not know the resistance of the cables including activated safety mat, you must determine the resistance through measurements.
Proceed as follows:
· Unplug the digital input module from the BaseUnit.
· Measure the resistance of the cables including activated safety mat between VSn and DIn+4.
· Measure the resistance of the cables including activated safety mat between VSn+4 and DIn.
For the above-mentioned measurements, the resistance must not exceed 100 ohms.
You can use the measuring tap of the BaseUnit for the measurements. For more information, refer to the ET 200SP Distributed I/O System (https://support.industry.siemens.com/cs/ww/en/view/58649293) System Manual.

With configured safety mat evaluation, short-circuits with L+, short-circuits with M and cross circuits to another channel are detected with configured safety mat evaluation. Both channels assigned to the affected safety mat evaluation are passivated.
To make it easier to determine the cause of the error, the red channel LED of the input affected by the short circuit/cross circuit lights up.

Behavior of the safety mat evaluation after wire break of the sensor supply cable or the cable of the digital input
With configured safety mat evaluation, the wire break is detected on all cables used for the connection of the safety mat evaluation. Both channels assigned to the affected safety mat evaluation are passivated.
To make it easier to determine the cause of the error, the red channel LED of the input affected by the wire break lights up.

Special features for fault detection
The detection of certain faults (short-circuits or discrepancy errors, for example) depends on the application, the wiring, and the parameter assignment of the short-circuit test and the sensor power supply. The corresponding tables for error detection can therefore be found in the applications under Applications of the F-I/O module (Page 37).
Detection of a cross circuit is not ensured in mixed operation between a channel with safety mat and a channel with 1oo1 or 1oo2 configuration.

Generally applicable information on diagnostics
For information on diagnostics which apply to all F-modules (e.g. reading out the diagnostic functions, passivation of channels), refer to the SIMATIC Safety - Configuring and Programming (https://support.industry.siemens.com/cs/ww/en/view/54110126) manual.

Value status

Properties

In addition to the diagnostic messages and the status and error display, the F-module makes available information about the validity of each input and output signal the value status. The value status is entered in the process image along with the input signal.

Value status for digital input and output modules
The value status is additional binary information of a digital input or output signal. It is entered in the process image of the inputs (PII) at the same time as the process signal. It provides information about the validity of the input or output signal.
The value status is influenced by all errors.
· 1B: A valid process value is output for the channel.
· 0B: A fail-safe value is output for the channel, or the channel is deactivated.

Assignment of inputs and outputs for the value status in the PII
Each channel of the F-module is assigned a value status in the process image of the inputs. You can find the assignment in section Address space (Page 35).

Response times

Introduction

The next section shows the response times of the digital input module F-DI 8×24VDC HF. The response times of the digital input module F-DI 8×24VDC HF are included in the calculation of the response time of the F-system. To do this, use the SIMATIC STEP7 response time table (https://support.industry.siemens.com/cs/ww/en/view/93839056).

Definition of response time for fail-safe digital inputs
The response time represents the interval between a signal change at the digital input and reliable availability of the safety frame on the backplane bus.
Times required for the calculation
· Maximum cycle time: Tcycle = 8.0 ms · Max. acknowledgement time (device acknowledgement time): TDAT = 16 ms
Maximum response time in an error-free scenario (worst case delay time, WCDT) for 1oo1 evaluation.
The following formula applies to a sensor supply without short-circuit test: Maximum response time (TWCDT) = 2 * Tcycle + Input delay The following formula applies to a sensor supply with short-circuit test: Maximum response time (TWCDT) = 2 * Tcycle + Input delay + T1 + T2
T1 = Time for short-circuit test T2 = Startup time of sensor after short-circuit test

Response times
Maximum response time in an error-free scenario (worst case delay time, WCDT) for 1oo2 evaluation.
The following formula applies to a sensor supply without short-circuit test: Maximum response time (TWCDT) = 2 * Tcycle + Input delay+ Discrepancy time* The following formula applies to a sensor supply with short-circuit test: Maximum response time (TWCDT) = 2 * Tcycle + Input delay + max (T1p + T2p, T1s + T2s) + Discrepancy time*
*) Is omitted for discrepancy behavior "Supply value 0"
T1p = Time for short-circuit test (sensor 1) T2p = Startup time of sensor after short-circuit test (sensor 1) T1s = Time for short-circuit test (sensor 2) T2s = Startup time of sensor after short-circuit test (sensor 2)
In case of a 1oo2 evaluation, the discrepancy time in the SIMATIC STEP7 response time table must be set to 0.

Equipment Manual, 04/2022, A5E50578307-AB

Response times

Maximum response time to external short-circuits (one fault delay time, OFDT)
Maximum response time (TOFDT) = Input delay + Tcycle + (n * Tcycle) + Sum[x=0...7](Tsx) Tsx summation term: (T1x + T2x) < Tcycle Tsx = Tcycle (T1x + T2x) >= Tcycle Tsx = max (T1x, Tcycle) + T2x

For deactivated sensor supplies or sensor supplies with deactivated short-circuit test, the value 0 has to be used in the formula for Tsx.

x = Sensor supply T1x = Time for short-circuit test T2x = Startup time of sensor after short-circuit test n = Number of sensor supplies with activated short-circuit test

The following section provides two examples for the calculation of the maximum response time to external short-circuits at an F-DI 8×24VDC HF, depending on the parameter assignment.

Example calculation channel 1: (4.2 ms +10 ms) >= 8.0 ms Ts = max (4.2 ms, 8.0 ms) + 10 ms = 18.0 ms

Maximum response time for discrepancy error for 1oo2 evaluation (one fault delay time, OFDT)
Maximum response time (TOFDT) = 2 * Tcycle + Input delay + 2 * max (T1p + T2p, T1s + T2s) + Discrepancy time

T1p = Time for short-circuit test (sensor 1) T2p = Startup time of sensor after short-circuit test (sensor 1) T1s = Time for short-circuit test (sensor 2) T2s = Startup time of sensor after short-circuit test (sensor 2)

Maximum response time with no faults (Worst Case Delay Time, WCDT) for safety mat evaluation
When the safety mat is activated (the contact is closed), the maximum response time is 17.6 ms.

Maximum response time in the case of fault (One Fault Delay Time, OFDT) for safety mat evaluation
If a safety mat evaluation is only configured on one channel pair, the maximum response time in case of a fault is 25.6 ms.

If a safety mat evaluation is configured on 2 to 4 channel pairs, the maximum response time in case of a fault is 33.6 ms.
