Hello Experts,

In my current assignment we have 1214C DC/DC/DC Cpu and 6 Qty of MKS make MFC valves. Which communicates on Profinet. We have configured each individual valve then take trial on 1 of the valve with PLC and it works fine. Then we have added another valve in system and trouble starts.

Any of 1 valves comes in communication and remaining valve shows BF error. If I remove cable form 1st valve then 2nd valve comes in communication and even I plugs 1st Valve cable its shows BF error even. Same way if I remove cable from valve 2nd then valve 1 comes in communication.

And if with my PG I go Online in PLC then both valves start showing BF. unless I go offline and restart system both valve remains in error. After restart same things happens as above.

I have tried to contact valve manufacturer then have no answer.

I have attached GSD file and all possible document I can get.

Hello,

sounds like problem with same IP /Name on the devices.

have you check that?

If both valves connected start accessible nodes and make a screen of the found devices.

Regards

Christoph

 I have same dought but there is nothing in valve where we can give them name or Profinet IP.

There is only port to give device IP to change/congif its other valve.

MKS has also said same thing Profinet IP will comes from its master (PLC).

Yes!!!!!!!!!!!!!!!!!!

Its done, I have used TIA to set IP and Node name.

Thank you so much.
