Functionality
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
function names. For example, the status indication of disconnectors or circuit breaker
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.
Operation principle
Status indication and validity check
The object state is defined by the two digital inputs POSOPEN and POSCLOSE, which
are also available as outputs OPENPOS and CLOSEPOS together with the OKPOS
according to Table 1331. The debounces and short disturbances in an input are
