Can you read the system time from the HMI?

Hi all,

Is it possible to read the system time from a HMIGTO2310/2315?

I have the PLC syncing the RTC time to the HMI using the 'Sys.setTime' function and I could just make the HMI display the last PLC variables used to write to that, however there's surely a simple way to read that time that's just been set directly from the HMI?

Hi,
There are system variables you can read: _Year4, _Year2, _Month, _Day, _Hours, _Minutes, _Seconds.

Hi @Fleo ,

Many thanks for replying, much appreciated. 

Ok, so there's no singular system variable I can read to display the whole time in one go, I'll need to read the variables and combine them into the time format I want.

If that's correct, what is the syntax layout for combining the time variables and how can I force desired formats such as 12/24 hour and if the am/pm flag is shown? Same question for the date as well really.
