Section 2-6
Allocation DM Area Settings for CPU Unit
Setting is written from the Programming Device (a Programming Console or
CX-Programmer) directly into the allocated DM Area (PLC Setup) 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 execution of the
STUP instruction.
The following table shows the words allocated in the DM Area and the set-
tings.
m = D (100
×
unit number)
Note
Set any value between 0000 and 0009 Hex for the communications baud rate.
The same baud rate will be used regardless of the value as long as it is
between 0000 and 0009 Hex.
Using the High-speed 1:N
NT Links
Compatible Host Units
Only the -V1 versions of the CS1-series CS1G/H, CS1-H-series CS1G/H-H,
and CJ-series CJ1G PLCs support the high-speed 1:N NT Links directly.
Other CS/CJ-series PLCs can use the high-speed 1:N NT Links indirectly
through a CS1W-SCU21 or CJ1W-SCU41 Serial Communications Unit. (If a
Serial Communications Unit is used, even CS1-series Units without the “-V1”
suffix can be connected via high-speed 1:N NT Links.)
Be sure to check the model number of the PLC and Serial Communications
Board/Unit before trying to establish the high-speed 1:N NT Links.
The following table shows which CS1-series PLCs can be connected to an
NT20 with the high-speed 1:N NT Links.
Note
(1) The direct high-speed 1:N NT Link connection is not supported by CS1-
series CPU Units without the -V1 suffix.
(2) A CS1W-SCB21 or CS1W-SCB41 Serial Communications Board or
CS1W-SCU21 Serial Communications Unit is required.
(3) A CJ1W-SCU41 Serial Communications Unit is required.
