20-mA Unit Serial

5.7.4.1
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.
