Hello

I've PCS7 6.1+SP1 + PDM 6.0+SP3.
In my configuration there are 140 PA field device on 8 Profibus PA networks, I working with pepperl+fuchs gateway with advance diagnostic module on the PA net.
Random some PA device was blocked by error mode on the PA_AO (or PA_AI), the error code(16#40xxxxxx) on the PA_AO driver block stopped the tranfer from the input of the block to the output. This when the PA field device funcion well without any problem. The error code on the block cannot be refresh and the device not tranfer the data in the PCS. The only way for solve the problem is to restart the device.
I've tested very well the phisycal layer of the Profibus PA network and we don't have any problem and all the parameter of the PA network (Siemens specification) was respected.
Someone know how is possible to adjourned the code of the driver PA_AO on PCS7.
Thanks in advance.

Dear Roby,

I fear this is tough one. I guess nobody is able to tell you what is wrong with your network, not without detailed measurements... without the exact value of the fault...

I think it is absolutely necessary for you to get a specialist on site, to figure out what is going on at all. Measurements on each network, especially in the event of the fault will be inescapable.

Please contact the international Customer Support to get a specialist on site, maybe your local distributor is also able to provide you special support on site, this would be much cheaper.

Best regards
