Error handling
Depending on the error that occurs during the command sequence, the error signal will
be set with a value. Table
these specified in IEC 61850-8-1 standard. The list of values of the "cause" are in

Bay control QCBAY

The functionality of the Bay control (QCBAY) function is not defined in the IEC
61850–8–1 standard, which means that the function is a vendor specific logical node.
The function sends information about the Permitted Source To Operate (PSTO) and
blocking conditions to other functions within the bay for example, switch control
functions, voltage control functions and measurement functions.
