Connecting to the RS-232C Port at the Host
When Using the Memory
Link Method

Reference:
For example, when connecting PTs with model numbers 3, 4, 5, and 6 to port
1, set the value 8200 Hex to DM32000, 000A Hex to DM32001, and 0006 Hex
to DM32006.
Connecting to a CS/CJ-series Serial Communications Unit
A CS/CJ-series Rack-mounting Unit:CS1W-SCU21(-V1)
CS-series Serial Communications Boards and Units with lot number 991220
(December 20, 1999) or later support the high-speed 1:N NT Link method.
Boards and Units with earlier lot numbers cannot be used.
Setting the Front Switches
Set the unit number of the Serial Communications Unit by using the rotary
switch located 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 fol-
lowing.
Allocation DM Area Settings for CPU Unit
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.
In the memory link method, the connection can be made to a personal com-
puter with RS-232 and an FA computer, etc.
When connecting to the host in the memory link method, it is necessary to
create a program for the memory link at the host side.

Set the unit number to 0 through F so
that it will not overlap with the numbers
