We've got a 315-2 DP with MMC which behaving a bit peculiarly. Despite having loaded an empty program and setting up the busses in Netpro to reflect the currently available devices the BF Led is on steady and the SF Led is blinking.
More curious is that in the diagnostic buffer, the CPU is reported as having gone from STOP to RUN with no faults. Despite that, the little fault symbol beside the CPU icon is showing a fault.
Anybody seen anything like this before and if so is there a solution?
Or are our increasing suspicions that the CPU is faulty, the most likely cause of this state of affairs, correct?
