Hi Christoph,

I was Checking the program in online mode, suddenly the hole of green color coupling in scout project went to red color state then i clicked offline button and online button again then i faced to this big problem that when i click online button it goes to online but immediatly comes back to offline and reports the strange target system output.I can reach online mode in HW Cofig and i can read data in opc scout also the HMI and process are working perfect.i tested the other X127 and X130 but the result was the same.

you can see the target system output in attach. 

At first should i sure after switch off and on the device will go to running state or not.because now every thing working, only i can not go online.

I can go online with HW config of this project.I send diagnostic massage from D425 in attach.

Hi Dear Christoph,

Today I was Won, After Switching OFF and ON, the device Went back to run.Now the online mode works properly. Only a little trouble is about missing the volatile data that take time for adjusting the process.

Thanks a lot,

Best Regards
