315 2PN/DP modbus tcp communication....

Post by alansal » Sun Mar 10, 2013 3:07 pm

Hi all,

The problem is; A 315 2PN/DP cpu is being used as a gateway (GW) to collect data from other cpu via profibus and sending via TCP, but somehow the slave seems not to be reading any data from my cpu. No configuration/logic changes were made but all of a sudden 2 weeks before this problem is occured.

My GW cpu can read datas from the source cpu, the ethernet wiring is ok (i can ping any other device).

I tried to collect datas from my GW but i could not succeed it as well. In this regard i want to check if gw is sendingbut i can not...

Please help me with any software, (if it includes any connection detail on how to collect INTEGERs from my cpu with address, it would be highly appreciated) or test method.

Kind regards,
