Function
OR
OR is used for a normally open bit connected in parallel. A normally open 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 begin-
ning 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 Basic Input Unit's 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 mem-
ory is read. If there is an immediate refreshing specification, the status of the Basic Input Unit's input terminal is
read.
