Dint to Time convertion on Siemens S7-315 CPU with TIA v11

Hi All,

Can anyone advice and share on the following?
- How can we convert Dint to Time format on S7-315CPU with TIA v11?
- If i need to insert a (TON)timer setpoint from HMI,how can i convert the msec to Hr,Min,Sec and finally the timer will display in countdown mode on the HMI.

Thanks and Regards

in SCL you can try with this: PT:=dint_to_time(variable)
in LAD and FBD i think there t_conv block that do the same.
as for STL i don't think it's possible.

if you need this a lot try with writing a function in SCL that has var for input and give time as return result.

PS: if using SCL you can go with integer, eg. dint_to_time(int_to_dint(variable))

i wrote a similar function once:

FUNCTION "T_min" : Int
VAR_INPUT
"Time_int" : Struct
"h" : Int;
"min" : Int;
END_STRUCT;
END_VAR

BEGIN
#T_min:=#Time_int.h*60+#Time_int.min;
END_FUNCTION

!!! IMPORTANT: do not forget that Timers have PT in msec, so multiply with right factor if you do not have time in msec already

Thanks Balash,
Im not fomiliar with other programming language than Ladder, can you please generate and share a function block which create by SCL ?

well the code is already written, but do as follows:
1. create new function T_dint, choose SCL for language
2. declare input paramter Time_dint DINT
3. declare function return value as TIME (default is void)
4. write: #T_dint:=dint_to_time(#Time_dint);

that's it

of course if #Time_dint is in minutes then everything has to be multiplied with 60000

EDIT:
or if you have hours, minutes and sec declared as inputs then use this:

#T_dint:=dint_to_time(((#hours*3600) + (#minutes*60) + sec)*1000);

vice versa function would have time as input and hours, minutes, sec as output:

#temp:=time_to_dint(#Time_ET)/1000;
#hours:=#temp/3600;
#minutes:=(#temp-(#hours*3600))/60);
#sec:=(#temp-(#hours*3600)-(#minutes*60));

that would be on the fly...
