RET
This bit memory bit shows whether the
function was carried out without errors. If
an error occurred, the function is exited
and the parameter is set to "1".
START_UP
This parameter activates and starts the
INTERBUS system once. In the event of
an error, the INTERBUS system is started
automatically after a cold or warm restart of
the PLC. However, this requires the bit
memory bit to be set during PLC startup.
