Sometimes the program is erased form the memory of the PLC. All the CPU LEDS start blinking. Checking the Diagnose Buffer is saw the following: A sucession of the same tipe of EVENT, since the 120th Event (as bellow) to the Event 53rd Event 120 of 120: Event ID 16# 3583 No entry in text database. Hexadecimal values will be displayed.

darkvader Posts: 17 Rating: (1)	Wizard, I've followed your advise. Chargins the new firmware and it seems to be ok now. What could be the cause of this behaviour, since this CPu is working since 2 1/2 years, and be solved apparently with a firmware upgrade? Thanks DV

Mario Braganca Posts: 124 Rating: (17)	Hi Darkvader I saw you did another question Load Memory - RAm and Flash Eprom in the Forum. Did you take out the memory with the power on? If you did this maybe the CPU is damaged, or maybe the memory card. There is no warranty for this. Regards Mario

While I was downloading a small bunch of FC’s to the CPU through ethernet connection, the connection suddenly was lost and the CPU stopped with all diagnostic led’s blinking. To regain communication with the CPU I had to use the MPI port. And then I found that the memory had been totally wiped out, both user and system data had gone.Do to the time pressure to get the system going again I had unfortunately no time to investigate and save samples from the diagnostic buffer. wan.
