VPK Posts: 19 Rating: (0)	Dear All, I have 4 OP177 hmi in my plant. Out of that4 Ops2 are showing the unexpected time, even if i had set it to the right time after few minutes it comes back to the very old time & year..i had checked the other OPs time settings which is working fine and found all the settings were same for both working and not working OPs. I cannot predict what could be the problem.Can anybuddy help me out who had the same experiance. Thanks in advance, regards, vpk
