Overview of Direct Connection Operations
Section 5-1
The PT status control area (PLC to PT) can be allocated to the following PLC
areas.
❍
: OK
×
: NG
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.
Note
(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 PLCs.
Note
Make sure there is no duplication in the PT status control area allocations and
PT status notify area allocations.
Note
When NT link (1:N) is set, the PT status control area must be set for each con-
nected PT.
