AC 800M PM856 is not pinging and showing Fault red light
I have AC800M PM856 which was in working before 2 months because of lock down plant was stooped. But now I am trying to pining it's not giving any response.
IP For controller is 192.168.0.2/255.255.255.0 and PC IP : 192.168.0.16 /255.255.255.0. I tried restart of controller but after restart directly showing red light in fault on controller.
After that I pressed INT small button to reset controller until run light blinking but unfortunately controller not giving any response still it shows fault light. Also replaced lan cable.
Please suggest me how to resolve this or what i should do with same??

Was there no power to the system for those two months? I'm guessing the controller lost its settings? Like a previous poster mentioned, if that's the case, you'll need to set it up with the serial link.

The IP address is part of the bootup messages.
If the controller halts (which seems to be the case here) the reason (e.g. memory error) will be output to the serial console.

Hi,
Normally, you don't have to loose the IP settings or firmware, even during a long miss of power supply?
Try to connect to the CPU by serial link (black cable TK212) to COM4. Update the firmware (serial firmware upgrade), then set the correct IP (IP Config). Restart the CPU (power off) after each procedure.
Finally, you have to download your application.
