I have a problem in SIWAREX-U Module,,When I replaced a new one there was no response at all & when I put the old one it worked good
I don't know what is the problem,however the Old one has a firmware version 0112 & the new one is 0114
The system is CPU 316-2DP 6ES7 316-2AG00-0AB0
I forgot to say that the New one & old one has the same Part No. 7MH4601-1BA01
So, I need to know how to overcome this problem
