[Setting the front switches]
Set the unit number of the serial communication unit by using the rotary switch lo-
cated on the front panel. Set each switch with a flat blade screwdriver so that the
values or symbols in the setting value window agree with the following.
Set the unit number to “0” through “F” so
that it will not overlap with the numbers
used in other
units.

[Allocation DM area settings for CPU]
Setting is written from the peripheral tool (a programming console or CX-Program-
mer) directly into the allocation DM area (system setting area) of the CPU. After
the setting is written, it becomes effective by turning the power ON, restarting the
unit, restarting the communication port, or execution of the STUP command.
In the following, the channel numbers of the allocation DM area and settings are
shown.
