Any known S7400 connection issues?

I have no trouble configuring S7300 device connections. However, cannot connect to any S7400 (e.g. CP443-1 communication processor) devices.

Nothing that I can think of unless you’ve got the wrong rack and slot configured (or those properties aren’t working correctly).

Maybe you can call into support and we can poke around?

Well, don’t I feel like a DA…I didn’t modify device advanced settings. All S7300 cpus are in slot 2 while 400s are in slot 4.

Thank you Kevin.

Hi MiddleC
I have exactly the same problem with a S7 400 and CP443. Did you find out how to make it work?

Hi!
I have a connection s7-400:
hostname = ip for CP443
rack number = 0
CPU slot number = 3

CPU slot is the problem for you ! The CP443 is in slot 4 the CPU is in slot 3., you need to put the cpu slot in ignition.
Verifi this and should work !

Best regards !

Thank you, it works :slight_smile:
