ETN21 Time Sync and DST

3 posts in this topic

I have setup the PLC to sync to the SCADA computer acting as NTP server each day at 02:01AM. During the setup, I need to put in the time offset from the time server for the PLC to apply. But this does not take daylight saving time into consideration. If I put in time offset of 10:00 hrs, it will only read non-DST time, which is one hour behind when DST is active. What is your recommendation in fixing this?

I found a FB here that enables a bit when DST is active. With this, is it possible to change the time offset in the program? Like if DST bit is ON, set offset to +11:00 and DST bit is OFF, set offset to +10:00.

I would have thought the NTP sewrver would have taken care of DST? Have a job here in Sydney where the IT guys got that to work - I do not know how - not into IT.
