Modicon Compact 984 Unresponsive

I have a compact 984 that I use Proworx Nxt to interface with. I can no longer go online with the PLC. Proworx spits back an error message (380) invalid command. My PLC does not look happy. The run light is blinking (3 blinks then pause). I have tried to cycle power to the PLC twice with no luck.

Does anyone have any experience with such an old platform?
