BOSTATE – The block reads the state of an output relay and outputs it as a Boolean value.
Type
UINT
BOOL
Recommendation: This block should be placed in the MW_BEARB level,
where it is cyclically updated
Note: In the task levels PLC1_BEARB and PLC_BEARB, changes of the
output relay are no trigger events for these levels. These levels are only
triggered by changes to indications routed onto them.
If the output relay with the number BO exists and the state of the associ-
ated output relay is active, STATE = TRUE is set, otherwise STATE =
FALSE.
ASWITCH – This block is used to switch between two REAL inputs (RMS values).
