Siemens SIPROTEC 5 User Manual

20-mA Unit Ethernet
Overview
The function 20-mA unit Ether.:
•
Communicates in series with a 20-mA unit via the Slave Unit Protocol (SUP) and records the values meas-
ured by the 20-mA unit
•
Transforms the measured 20-mA values into slowly changing process tags 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
Structure of the Function
The function 20-mA unit Ether. can work only in the function group Analog units. A maximum of 4 function
instances can work simultaneously. Each instance contains 12 preconfigured channel function blocks.
The function 20-mA unit Ether. contains input and output channels which can be configured independently
of one another.
