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 specifica-
tion, 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.
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 CPU Unit’s built-in input terminals is read.
