20-mA Unit Serial
Overview
The function 20-mA unit Serial:
•
Provides serial communications with a 20-mA unit via the Modbus protocol and records the values meas-
ured by the 20-mA unit
•
Transforms the measured 20-mA values into slowly changing process variables such as temperature or
gas pressure
•
Makes the recorded process tags available to CFC, GOOSE, protocols and the device display
•
Monitors communication with the 20-mA unit
The function 20-mA unit Serial is structured in the same way as the function 20-mA Unit Ether.. The mode of
operation is also identical. The only difference is that the measured values are transferred to the communica-
tion module via a serial connection instead of an Ethernet connection.
You can find more information in Chapter 5.7.3.2 Structure of the Function.
Application and Setting Notes
Parameter: Port
•
Default setting (_:2311:103) Port = Port J
With the Port setting, you specify the slot for the communication module that will be used for the connection
with an external 20-mA unit.
Parameter: Channel number
•
Default setting (_:2311:105) Channel number = 1
