%U Address: It is an internal memory of PLC CPU used to read and
write to the specific area of the special/communication module (data to
read periodically is specified in module) in MasterLogic-200 PLC per
scan.
Data that is changing frequently is stored in this area of the CPU. Like
the other devices, it can be directly used for general instructions such as
MOV, CMP, ADD, and so on (while PUT/GET instructions need to be
used for parameter area of the module.)
