CPU Unit Allocation DM Area Settings
Setting is written from the Programming Device (a Programming Console or
CX-Programmer) directly into the allocation DM area (system setting area) of
the CPU Unit. After the setting is written, it becomes effective by turning the
power ON, restarting the Unit, restarting the communications port, or execu-
tion of the STUP command.
In the following, the channel numbers of the allocation DM area and settings
are shown.

Set any value between 0000 and 0009 hex for the baud rate. The same
baud rate will be used regardless of the value as long as it is between 0000
and 0009 hex.
When connecting PTs with model numbers 3 to 6 to port 1, for example, set
the value 8200 hex to DM32000, 0000 hex to DM32001, and 0006 hex to
DM32006.
