Hello, My CPU 315 went to STOP mode and I can not take it back to RUN mode. This CPU has been working properly during last days but today, when I powered it on, this problem appeared. When CPU is on, I find the following light status SF Continuous ON BF1 Blinking (probably because not all the ET200 modules are yet connected to it) BF2 Blinking (probably because not all the ET200 modules are yet connected to it) MANT OFF DC5V ON FORCE OFF RUN OFF I have tried to do the following things, but none of them works: - Restart CPU - Reset CPU through MRES switch: It seems reset procedure is performed properly but when I connect to the CPU, none of the FB, FC, DB,... has been deleted - Hot restart from Step 7 software: CPU stays in STOP mode I checked the buffer diagnosis and I found the following messages (find screenshots attached in spanish) that appear just righ before CPU is sent to STOP mode: - Access error to the perphery, when reading - Access error to the periphery, when writting - Access error to the periphery when updating the process image I opened the event help but I didn't find anything clear about the problem. I searched for this problem online but I could not find any solution. I would appreciate if you could throw some light to this issue. Thank you ------------------------------------------------------------------------------------------ |
