Connecting to a CS/CJ-series Serial Communications Unit
CS/CJ-series Rack-mounting Units:
Setting the Front Switches
Set the unit number of the Serial Communications Unit using the rotary
switches on the front of the Unit. Set the number or symbol in the setting dis-
play window in the following way using a flat-blade screwdriver. When using a
CS/CJ-series Serial Communications Unit set the switches as shown below.
DM Area Allocation Settings
From the Programming Device (i.e., a Programming Console or CX-Program-
mer), write the settings directly to the CPU Unit's DM Area Setup Area. After
the settings have been written, they will be enabled when the power supply is
cycled, the Unit is restarted, the communications port is restarted, or a STUP
instruction is executed.
The DM Area words that are allocated and the contents of the settings are
given in the following table.
With the memory link method, the connection can be made to a personal
computer and an FA computer with RS-422A.
When connecting to the host with the memory link method, it is necessary to
create a program for the memory link at the host side.

Allocated DM Area
For example, when connecting PTs with model numbers 3, 4, 5, and 6 to
port 2, set the value 8200 hex to DM32010, 000A hex to DM32011, and
0006 hex to DM32016.
