help me, pls

Sry, my english not good!!!!!!

Hi,

I have faced this issue recently. Here is the scenario:

I had an S71500 PLC and it was communicating with Allenbradley via Modbus TCP/IP. After configuring the communication block Modbus Client in S71500. , we have found that the block was returning an error with status code 80CE. To solve this issue we had to check the ethernet cable or optical cable which was laid between both PLCs. To do this we had pinged the IP address of the Allenbradley PLC from the other end. We found that the cable between the PLCs had issue. Once that was solved all the issues ended.
