2.4 Basic Characteristics of HART Analog Module
2.4.1 Summary
HART analog input module is a product that can use HART communication along with analog conversion. HART analog input module supports interface for communication by being connected with HART field device. Communication data provided by HART field device can be monitored via HART analog input module and status of field devices can be also diagnosed.
(1) Advantage and Purpose of HART Communication (a) Additional wiring for communication is not needed(Communication by using 4~20mA wiring of analog module) (b) Additional measurement information through digital communication (c) Low power consumption (d) Various and rich field devices that support HART communication (e) Display of field device’s information, maintenance, diagnosis
(2) HART Communication Composition HART communication consists of masters and slaves and up to two masters can be connected. PLC HART analog input module is connected as the primary master device and communicates with field devices-slaves. A communication device is connected as the secondary master device to diagnose field devices and set its slave’s parameters.
Smart mass flow meter provides flow’s field measuring values with the flow meter’s current signal. Along with signal current indicating flow, it sends additional measurement information measured by the flow meter to HART communication. Up to four variables are provided. For example, flow as the Primary Value (PV), stop pressure as the Secondary Value(SV), temperature as the Tertiary Value(TV) and current signal’s digital value as the Quaternary Value(QV) are used as measurement information. (3) Multidrop Multidrop method consists of only one pair of wiring and all control values are transmitted in digital ones. All field devices have polling addresses and the current flow in each device is fixed to the minimum value (4 mA). Notes – Multidrop method is not supported on HART analog input and output module.

2.4.2 RT Operation
(1) HART signal The figure below illustrates HART signals whose frequency is modulated to analog signal. In this figure, HART signal is shown as two kinds of signals that have frequency of 1,200 and 2,200 . These two kinds of signals refer to binary number 1(1,200 ) and 0(2,200 ) and they are recovered to meaningful information by being demodulated into digital signal on each device.

(2) Kind and Configuration of HART Commands
Kinds of HART commands are described. HART analog input module transmits HART commands to HART field device and HART field device transmits responses to the commands to HART analog input module. HART commands can be categorized into three command groups according to their characteristics and they are called Universal, Common Practice, and Device Specific. Universal commands shall be supported by the entire HART field device manufacturers as an essential command group. Common Practice defines only data format of commands and manufacturers support only items that are judged as essential ones for HART field device. Device Specific is a command group that has no specified data format. Each manufacturer can define it if needed.

3.2 Wiring
3.2.1 Precautions for wiring
(1) Don’t let AC power line near to 2MLF-AC4H Module’s external input sign line. With an enough distance kept away in between, it will be free from surge or inductive noise.
(2) Cable shall be selected in due consideration of ambient temperature and allowable current, whose size is not less than the max. cable standard of AWG22 (0.3 ).
(3) Don’t let the cable too close to hot device and material or in direct contact with oil for long, which will cause damage or abnormal operation due to short-circuit.
(4) Check the polarity when wiring the terminal. (5) Wiring with high-voltage line or power line may produce inductive hindrance causing abnormal
operation or defect.

Notes
(1) In current input, there will be no accuracy tolerance caused by cable length and internal resistance of the source.
(2) Set to enable the channel only to be using. (3) 2MLF-AC4H module does not provide power for the input device. Use an external power
supplier. (4) If you do not separate the DC power of the transmitter each channel, it can affect the
accuracy. (5) In consideration of the current consumption of the transmitter, please use the external power
supply of sufficient capacity. (6) If you configure the system to provide the power of several transmitter by a external power
supply, please be careful not to exceed the allowable current of the external power supply the total current consumption of the transmitter.

3.2.2 Maximum communication distance
(1) HART communication is available up to 1 . But, if a transmitter presents the max communication distance, apply the shorter distance among the transmitter’s communication distance and 1 .
(2) The max communication distance may vary according to the cable capacitance and resistance. To ensure the max communication distance, check the cable’s capacitance and length.
(3) Example of cable selection to secure communication distance (a) If the cable capacitance is less than 90pF and the cable resistance is less than 0.09, the distance available for communication will be 1 .
(b) If the cable capacitance is less than 60pF and cable resistance is less than 0.18, the distance available for communication will be 1 .
(c) If the cable capacitance is less than 210pF and cable resistance is less than 0.12, the distance available for communication will be 600m.

Notes HARTCMND command or HARHCLR command is executed by setting bit of a corresponding command while HARTRESP command is set by inputting a command number. For example, if command 57 is executed, enter H0400 (K1024) to operand S for HARTCMND command or HARHCLR command and enter command K57 to operand S for HARTRESP command. Here, H0400 is a hexadecimal to set bit10- command 57.
