After uploading the program on the CPU(s7-ET200sp) error light starts blinking on the cpu. Modules are shows okay. when i diagnose online it says

even though i have setup the  startup to warm restart. In my network i have totally three component. one HMI, Servo drive and PLC. when i use the network switch to communicate PLC does not communicate with HMI or drive. even when i use command prompt it does not work but when i connect it directly to PC it communicate but the error light would be still on. Please help me in this i am stuck on this from past 4 days

Hello

Thank you for your answer. there are no interrupt OBs. but the error light disappeared for the same program. I downloaded the blank program and then again downloaded my program. after that the error didn't pop up. I still wanna know the possible reason behind this.

Hi,

"I still wanna know the possible reason behind this."

On the screenshot, not all events can be seen.

In my opinion, without the complete diagnostics buffer, it is hard to tell what the reason could be.

Helpful is always to save the complete diagnostics buffer as.txt file with button "save as".

I HAVE ATTACHED THE TXT FILE. I HOPE THIS MIGHT BE USEFUL. THE ERROR COMES FREQUENTLY. I STILL CAN NOT FIND THE REASON. 

 Hi

did already check the actual module and the configuration is same? i check the diagnostic that you send you have different from actual
