Logic of the Function 20-mA Unit Ethernet
Communication with 20-mA Unit
The function is used to communicate with a 20-mA unit connected via an Ethernet connection. When a
connection of the function to an external 20-mA unit via an Ethernet interface has successfully been estab-
lished, the 20-mA unit sends the measured values of all connected channels to the function 20-mA unit.
Ether.. For the connection to be established successfully, specific communication settings must be specified.
You can find more detailed information in Chapter 5.7.3.4 Application and Setting Notes .
The 20-mA measurement unit 7XV5674 is supported.

Error Responses
Error Description Status Health
The function 20-mA unit Ether. cannot establish a
connection with a communication module.
Alarm
The function 20-mA unit Ether. sends TCP settings to
the communication module, which evidently would
like to connect to the 20-mA unit via a serial protocol.
This communication module does not establish a
connection to the 20-mA unit.
Alarm
The connection between the communication module
and the 20-mA unit causes a time-out indication.
