Areas for Control/Notification
This section describes the basics for operating the NT11 through communica-
tions with the PLC using the host link/NT link.
4-3-1
Allocatable Bits and Words
The following bits and words are allocated to the PLC and used for the NT11
operation. The range of respective area varies with the type of PLC.
The allocations must be made without exceeding respective area range.
[OMRON PLCs]
Words Allocated for the PT Status Control Area
Words can be allocated for the PT status control area (host
«
PT) in the fol-
lowing host (PLC) areas.
*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.
The Auxiliary Area of the CVM1 and CV-series PLCs is allocated to system
functions, and cannot be used for purposes other than system use.
The range of each memory area differs according to the PLC.
4-3-2
Data Exchange in the Host Link/NT Link
There are two main methods for data exchange when using the host link/NT
link, as follows:
• Using the PT status control area/PT status notify area
• Allocating numeral memory table entries/character string memory table
