Question

Can the contents of the DM Area in CS1 or C200HX/HG/HE Programmable Controllers CPU Units be written to or read from a personal computer even when the CPU Unit is operating?

Answer

The DM Area can be written to or read from a computer even while the CPU Unit is operating. When the CPU Unit is in MONITOR mode, both reading from the CPU Unit to the computer, and writing from the computer to the CPU Unit are possible. When the CPU Unit is in RUN mode, only reading from the CPU Unit to the computer is possible. The DM Area can be written to or read using WS02-CXPC1-J FA Integrated Tool Package (CX-Programmer), or using user programming on the computer.
