Note 1. LR 00000 to LR 00199 are converted to and used as I/O area words CIO 01000 to CIO 01199.
2. C200HX/HG/HE-E/-ZE PLCs are the only C-series PLCs that support the EM Area (EM). All bits in the
AR Area for CVM1/CV-series PLCs are allocated for system functions and cannot be used for any other
application.
The ranges for each area vary with the PLC model. Refer to
Appendix 3 PLC Memory Areas
. Refer to
System Settings and Project Properties
in the
CX-Designer Online Help
for details on allocation meth-
ods.
Set a BOOL variable with 64 elements when allocating a tag.
