This year, the day of the week program has shifted its schedule, now changing two hours earlier at 10 P.M. rather than the usual midnight. This change took effect at the beginning of the year.
Are you synchronized with a time server? Have you chosen a local timezone or Greenwich Mean Time (GMT)?
Ken Moore inquired: "Are you synchronized with a time server? Have you chosen the local time zone or Coordinated Universal Time (GMT)?" I am utilizing the PLC time set to Eastern Standard Time, and the clock is displaying the correct time. The data transmission is functioning as expected, but there seems to be a discrepancy in the date change occurring at 10:00 PM (hour 22).
Are you referring to utilizing the WallClockTime object in PLC programming to determine the "Day of the Week", or are you transferring the "Day of Week" information from a HMI/SCADA system to the PLC?
When using a PLC set to Eastern time, the clock is correct, but the day changes at 10 PM. Can you provide more details on the display showing Eastern time and the accuracy of the clock? Additionally, could you elaborate on the PLC's decision-making process for data movement? Does it rely on GSV WALLCLOCKTIME/DateTime or WALLCLOCKTIME/LocalDateTime for its logic? This information will help troubleshoot the issue more effectively.
Do you know where the DOW information is sourced from? Have you checked the AOI or sample code? As far as I remember, the default GSV does not include a DOW function.
I genuinely think this change is highly beneficial for those of us who prefer to hit the hay earlier. Now, I can catch the end of the program without having to stay up till midnight. Plus, it allows for a broader audience, including older folks and young individuals that adhere to a stricter sleeping schedule. However, I do understand how frustrating this time shuffle could be for night owls. It just goes to show, you can't please everyone all the time.
