Error handling
Depending on the error that occurs during the command sequence, the error signal will
be set with a value. Table
197 describes vendor specific cause values in addition to
these specified in IEC 61850-8-1 standard. The list of values of the “cause” are in
order of priority. The values are available over the IEC 61850. An output L_CAUSE
on the function block indicates the latest value of the error during the command.

12.1.9.2 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.
