5.1.11.1. Configuring the trip circuit supervision CMTCS_
The Relay Configuration Tool can be used to connect the trip circuit supervision
input status signals to the function blocks CMTCS1 and CMTCS2. The
configuration of the blocking signal is user-specific and can only be defined in the
machine terminal configuration. The trip circuit supervision inputs in the machine
terminal configuration are as follows:
TCS1 and TCS2 inputs in REM 543 and REM 545:
