I’m trying to get system time using SysTimeRTCHighResGet function from SysTimeRTC library, but getting 0 returned. How do I get local time, that I can use in the program?

To get the local time in your program, we recommend using the following approach:

  • Use SysTimeRtcGet to retrieve the system time in DWORD format.
  • Then, convert this DWORD system time to a readable date and time format (year, month, day, hour, minute, second, microsecond) using SysTimeRtcConvertUtcToDate.
  • If you need to convert a date and time structure back to DWORD format, use SysTimeRtcConvertDateToUtc

For more information on HMI system times here is a resource:Demo Project

Thank you. It works with SysTimeRtcGet function.

I am having the same issue as the SysTimeRtcGet is just retreiving a 0. I have tried HighRes as well and get the same result. Any ideas?

Thanks

Hi @vick32w ,

Could you send us screen shot of your project so we can take a look at your set up and see if we can spot the issue.

Thank you!

This works for me

VAR
SystemResult : UDINT;
TimeStamp : UDINT;

END_VAR

// Get CPU Timestamp
TimeStamp := SysTimeRtc.SysTimeRtcGet(SystemResult);

Also tried the SysTimeRtcGet with the result being a UDINT instead of a DINT and still returned a 0.

Thank you,

The video I watched did not have anything on the right side of the function. I really appreciate it.

Have a great rest of your day.
