I have 8 identical systems running the same code, but one of them consistently gains 30 seconds every day, resulting in a time discrepancy with the other systems. This issue is not caused by any specific time or date code running on the machines. Do you have any suggestions for troubleshooting this time discrepancy?
Is there a way to perform a factory reset on your device, reinstall your applications, and observe the outcome?
Alanvan69 suggested brainstorming for solutions. A deviation of 30 seconds per day, roughly equivalent to a third of a tenth of a percent, is a potential issue within the device's specifications. However, this margin for error may not be significant in an industrial environment. If this level of accuracy is insufficient for your requirements, consider further analysis and adjustment every 48 minutes.
To begin with, consider replacing the battery in your HMI device. The specific model of HMI you have not been disclosed, but this solution is compatible with Crimson 3.0 and potentially earlier versions. By searching the manual for information on SNTP, you can configure a reliable timekeeping system by setting up an SNTP server with a 'good' timekeeper and an SNTP client with a 'bad' timekeeper. If necessary, you can program the 'bad' clock to correct itself every minute. Additionally, if you have internet access, the SNTP client can sync with an online NTP server. Alternatively, you can link a GPS sensor to one of the serial ports for accurate timekeeping according to the manual for the Graphite HMI device. It is important to note that the battery in the HMI unit is responsible for maintaining time accuracy when the device is not powered, with a typical drift of less than one minute per month at 25°C.
Have you checked the NTP (Network Time Protocol) configuration on that particular system? Sometimes, if it’s not syncing correctly with the time servers or if it’s set to an incorrect timezone, it can cause these discrepancies. It might also be worth looking into whether there's any hardware issue, like a failing RTC (real-time clock) battery that could be affecting the timekeeping. Additionally, reviewing the system logs for any related errors around the time the discrepancy occurs might provide some clues.
That’s an interesting issue! It might be worth checking the time synchronization settings on the systems; make sure that the problematic one is set up to synchronize with a reliable time source like NTP (Network Time Protocol). Also, check for any differences in the hardware clock settings or power-saving features that could affect its timekeeping. It could even be a process running on that specific machine that’s interfering with its clock, so looking into running processes and services might help diagnose the problem!
That’s a puzzling issue! I’d start by checking the time synchronization settings on the problematic system. Make sure it's configured to sync with a reliable NTP server, as drifts can occur if the clock isn't regularly corrected. Also, look into any differences in system load or resource usage that might affect timekeeping, like excessive CPU throttling or power-saving settings that could cause clock skews. Lastly, getting into the BIOS settings to ensure the hardware clock is set correctly might help; sometimes, a dying battery can cause odd behavior too. Good luck!
