Function
OR
OR is used for a normally open bit connected in parallel. A normally open bit is configured to form a log-
ical OR with a logic block beginning with a LOAD or LOAD NOT instruction (connected to the bus bar or
at the beginning of the logic block). If there is no immediate refreshing specification, the specified bit in
I/O memory is read. If there is an immediate refreshing specification, the status of the CPU Unit's built-
in input terminal is read.
OR NOT
OR NOT is used for a normally closed bit connected in parallel. A normally closed bit is configured to
form a logical OR with a logic block beginning with a LOAD or LOAD NOT instruction (connected to the
bus bar or at the beginning of the logic block). If there is no immediate refreshing specification, the
specified bit in I/O memory is read. If there is an immediate refreshing specification, the status of the
CPU Unit's built-in input terminal is read.
