CI867 COMMUNICATION WITH DIFERENT NETWORK SEGMENT
I have a CM 800 PLC with CI867 module, i need communicate the PLC with 4 remotes Data logger, but when I try the communication,i not successful because the module and the Data loggers has different networks segments, that is, the PLC has the following configuration:
IP:10.14.82.33
MASK:255.255.255.240
GTW:10.14.82.46
And the Data loggers has the following configuration:
10.14.82.82 until 97
MASK: 255.255.255.240
GTW: 10.14.82.94 and 110
The configurations are different by the internal company policies.
Would you mind helping me with this configuration?
Thank.

Hi, It's seem a switches configuration issue. Due Master and Slaves are in the different networks, it should necessary route the communication by the gateways devices.
I'll try to explain me. Let focus in the last octet of the IP addresses
CI is in "0010 0000" network
Meanwhile, Data Logger from 82 to 95 are in "0101 0000" network
And, Data Logger 96 and 97 are in "0110 0000" network
As you probably know, the mask acts like "and" bit operation in order to split the networks
It happens the same with Gateways, they belong in its respects networks:
That means gateways should knows how to transfer and back from "0010 0000" network to both nets "0101 0000" and "0110 0000", that it's achieve configuring the switches by routing
Good luck
