Structure of the Analog Unit Function Group
Gray: Optionally Wired, optionally available
White: Always wired, always available
The Analog units function group has interfaces to protection function groups. The Analog units function
group provides measured temperature values that come from an external RTD unit . These measured tempera-
ture values are available for all protection function groups in which a temperature monitoring function works.
The RTD unit Ether. function is not preconfigured by the manufacturer. A maximum of 20 function instances
can operate simultaneously.
The RTD unit serial function is set up structurally exactly in the same manner as the RTD unit Ether. function.
