Hello Guys,
I am facing a problem on automatic warm restart of CPU 315-2DP in case of Profibus Communication failure (during power loss). I am using CPU315-2DP to control 8 DP slaves in a profibus network. During testing one of the DP slaves i tried to power off it and ON again. When i Power off DP slave, the CPU "SF" & "BF" LED is both ON. Once i turned on the power the "BF" is cleared but the SF is still ON. I need to do a manual "Warm restart" to start the CPU again. Do i need to download any OB into the CPU for automatic restart once all the faults are cleared? Can somebody help me in this problem.
with regards,
Muthu
