PLC Memory Mapping

The PLC Memory can be defined in 3 major sections:

• Memory Area for User Programming. This area is controlled by the programmer for any use in the application programming.

• Memory Area for PLC I/O. This area is designated for the Physical I/O of the PLC.

• Memory Area for PLC Flag Registers. This area is updated by the PLC to show the system status. The user can reference these registers in the programming.
