Since the AR area bits of the CV-series PLCs are allocated to the system,
they cannot be used for purposes other than the system use.
The range of respective area varies with the type of PLC.
(1) LR 00000 to LR 00199 are converted to CIO 01000 to CIO 01199.
(2) The EM Area is supported only by the C200HX/HG/HE-(Z)E.
1. Use the Support Tool to allocate the PT status notify area (PT to PLC) to
the PLC memory.
