CPU-417-4H Sync issue

Hi Team

There is a Sync issue on CPU-417-4H Sync issue, after troubleshooting we confirmed the sync module is faulty (650-1AA04-0XA0). Now this module is discontinued without replacement.

Please advise if we should just buy new x2 CPUs or???

Hello AutoGen_4384816,

Maybe because of the product life cycle:

S7 SYNC-MOD. V4 F. S7-400H/F/FH

It is best that you contact your usual Siemens sales representative for advice on how to proceed.

Hi,

As you said your Synch Module expire in 2023 .

Here are the possible scenario in your case

1-Now you need to search same Synch Module from Market .

2- Buy two CPU's with same version of Hardware and same version of firmware and then download your whole program into it and Switch these CPU into H mode then these CPU will be Synch and working normal.
