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
