EZIO8SA stop respondind after a while

I have ran into this issue quite a few times in the last weeks, Everything works well in general but for an unknown reason the EZIO8SA stops responding and then I can hear the relays click about every second.

If I unplug the 8SA from the PLC (hard reset!) and then replug it, it goes back to working well for a while (between 1 hour and a couple of days)

Any Idea what could cause this behaviour?

Thanks

Dan, if you are hearing the relays click once per second, it would seem that the unit somehow is being put in diagnostics mode. This would be command 0x4F/0x0E. To take it out of this mode, it would have to get command 0x4F/0x0F

I don’t understand what could be sending this command to set it in diagnostic mode, this happens randomly after a day or two…
