Function
AND
AND is used for a normally open bit connected in series. AND cannot be directly connected to the bus bar, and
cannot be used at the beginning of a 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.
AND NOT
AND NOT is used for a normally closed bit connected in series. AND NOT cannot be directly connected to the
bus bar, and cannot be used at the beginning of a 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 the Basic
