Remote Maintenance and Monitoring of a PLC on
a Trolley in an Automated Warehouse
Example
I can safely maintain the PLC
on the trolley because I can
monitor remotely from
the network computer (CX-
Programmer) without having to
connect to the PLC
every time.

Programmer
RS-232C
It is difficult to start, change, or
do maintenance on the PLC
on the trolley because the CX-
Programmer has to be
connected directly to it.

Note: Supported by Serial Communications Units only.
Use PLC Links for exclusive control on PCB carrier
loaders and unloaders, or to exchange temperature
and time information on conveyor ovens.

NS-series PT.
Serial PLC Links
Data links can be created between up to nine CJ1M PLCs with up
to 10 words each using the built-in RS-232C ports. RS-422A
Adapters (CJ1W-CIF11) can be used to easily convert between
RS-232C and RS-422A.
Total cable length: 50 m max.
NT-series and NS-series PTs can also be
connected as slaves to the PLC Links
using a 1:N NT Link. Data is exchanged
only with the master CJ1M PLC.
One slave node is allocated for arch PT.
