The functions DCSXSWI and ESSXSWI indicate remotely and locally the open,
close and undefined states of the disconnector and earthing switch. The functionality
of both is identical, but each one is allocated for a specific purpose visible in the

truck can be monitored with the DCSXSWI function.
The functions are designed according to the IEC 61850-7-4 standard with the logical
node XSWI.
