Allocation DM Area Settings for CPU Unit
Settings are written from the Programming Device (a Programming Console or
CX-Programmer) directly into the allocated DM Area (PC Setup) of the CPU
Unit. After the settings are written, they become effective by turning the power
ON, restarting the Unit, restarting the communication port, or execution of the
STUP instruction.
The following table shows the words allocated in the DM Area and the settings.

*1 Set the Host Link baud rate at 9,600 bps or 19,200 bps with the memory
switch at the NT21. For details, refer to Setting the Host Link Method (page
127).
Either set PC Setup directly from a Programming Device (e.g., SYSMAC Sup-
port Software), or transmit the PC Setup made at a Programming Device to the
CPU Unit.
For details on the PC Setup, refer to the SYSMAC CVM1/CV500/1000/2000 Op-
eration Manual: Ladder Diagrams (W202-E1-j).
