Hello All,
Using a Micro1400 thanks to its DNP3 capability. DNP3 spec requires syncing PLC to a UTC source. However, my local HMI needs to be able to read from a local time source to display date/time correctly for alarms.
I could have HMI run freely, but then operators will need to set time on HMI manually every DST change. I'd rather not have them touch more than they need to...
Thus my problem. Anyone got any cool tricks that I might not be aware of to convert UTC to local time inside logix500? 5000 has the wallclocktime GSV, i don't believe 500 has anything similar...
Appreciate the help!
