When using the Memory
Link Method
Connecting to the Host’s RS-422A/485 Port
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.
Connecting to a CS/CJ-series Serial Communications Board
CS/CJ-series Rack-mounting Units:
CS1W-SCU31-V1 (Port 1 and port 2 are both RS-422A/485 ports.)
CJ1W-SCU31-V1 (Port 1 and port 2 are both RS-422A/485 ports.)
CJ1W-SCU41(-V1) (Port 1 is an RS-422A/485 port.)
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.
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 table, the relevant word addresses in the allocation DM area
and settings are shown.
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.
