MP-122 PLC 115-108
PLC 115-108 (MP-122) displays the status of the internal PLC control bits 115-108 (See graphic below). A “1” in any bit
indicates that the bit is “active”. These internal bits (control relays) can be used as global “control relays”. For
example, they can be used to create one-shots or latches. They can also be used to simplify programming.
