Displaying Countdown time on HMI?

Hello.

I want to display a countdown on a few times I am using. I am using T_SUM to subtracting the ET from the PT time and storing it as Time format. I monitor the countdown (CD) value and it is showing a countdown.  I cannot find a way to display the time on the HMI. If I on the other hand store the CD in Time_of_Day then I can display it both with the I/O field and the Date/time field but it displays it as 12H time format. That means that if the CD is say 1h, 30 min and 0 s then that would show 1:30:00 PM then when the CD has reach 0h, 30m and 0 s then it would show 12:30:00 AM. Is there a way to change the I/O or Date/time field do display in 24H format or is there another simpler way of doing this?  

PS: i am using an S7-1200 PLC and a TP1500 camfort HMI.

Hi HannAri

I wouldn´t use a DateTime field

I would split the Time Information in PLC in Integer Values for Hour, Minute, Second, millisecond.

Then use these Integers in the Panel to build your picture then you can set the format as you want and you can use a Text field vor signs between like : or .

A Date Time Format field is always used for a Timestamp and not for a timer Value.

I Hope it helps

 Hi Murof.

Thanks for your suggestion. Data type time is a rage between T#-24d20h31m23s648ms and T#+24d20h31m23s647ms stored in 32 bits. How would I go by splitting that into H, m and s?
