(2) Remote connection by RS-422/485
[Figure 5.1.15] indicates XG5000 and local PLC is connected into CPU module by RS-232C cable,
in case RS-422/485 channel of Cnet I/F module connected at local PLC communicates, it is figure
indicating remote connection example to remote PLC. Like figure, XG5000 can control program of
remote PLC by remote connection through remote connection function between Cnet I/F modules.
[Figure 5.1.15] Remote connection in case of RS-422/485 communication
Note
Basic parameter of remote server connected through XG5000 should be set as server, in case of
remote client, it should be set P2P client.
If you try remote connection when there is many communications, connection may fail. You
should convert PLC as Stop mode and stop communication before remote connection.
Remote connection sequence by using dedicated modem is as follows.
(a) Set basic parameter of remote server as XGT server.
(b) Convert local connected PLC into Stop mode.
(c) Execute XG5000 and select “Online – Connection settings” and set connection method. And
select connection method RS-232C and communication channel. This is same with case of local
connection. At this time, you should set station number of remote server to connect.
