logic operation

What is 'logic operation'? What does 'logic operation' mean?

A function to use the result of logic operation for event input operations, auxiliary outputs, or control outputs. AND or OR operations can be performed on up to four input conditions from external contact input, internal status, work bits, etc. More than one set of logic operations can be performed simultaneously, and output delays and reversals are possible. This enables, for example, easily changing operation based on Temperature Controller status without using processing in a PLC.
