If it is possible please can you show. My entire program is in Ladder. Please help. Thanks ixo65 To do both, you need a total of four number fields in TIA: 1 x input / output field for setting the hours 1 x input / output field for setting the minutes 1 x output field for displaying the remaining hours 1 x output field for displaying the remaining minutes An example file and the UDF are attached. ------------------------------------------------------------------------------------------ Split from Logo 8 and HMI. How to show remainding counter time.

The split block is a UDF. UDF can only programmed in FBD, not in LAD. That's why I created a LAD program for you that contains both the "Time_split" program and the function of the "Time_split" block. Attachment Time_split_LAD_0BA8.Standard.zip (15 Downloads)

I want it to read from HMI and stay the same. Tabindah THANKS A LOT AGAIN DEAR. ALSO I AM READING VALUE FROM AN OFF DELAY TIMER.

If you now want something different or don't understand parts of the implemented program, I can only help you if you describe exactly what you want.

Hi,

Thanks for the Splitting program. helped a lot. Can you please specify a formula that you used ?

Like i didnt understand why you used 29 as threshhold On 7 Off in SF004.

Also I didnt understand why you were comparing using analog comparator.

So if you have a math formula which u used to convert minute to hours:minutes, I will like to learn it.

Is it possible to make this splitter block in LAD logic?
