How can I convert from Real format to S5Time format ?For example:
1.000 ----> 1s ---> S5T#1S
0.9 ----> 0.9S ----> S5T#900MS
0.825 ----> 0.825S ---> S5T#825MS....ETC.

Hello,

Code:

L #YourTime                // real format
L 1000.0
*R
RND                           // here you get DINT in ms.
T #YourTime_in_ms

      CALL  "TIM_S5TI"   // FC 40 from Standart library -> IEC functions
       IN     :=#YourTime_in_ms
       RET_VAL:=#S5_time_output

Regards.

FB41 TI parameter is a TIME, not an S5TIME.

Just use SKHODRANS suggestion how to convert a REAL in seconds to a TIME in milliseconds. Ignore the TIM_S5TI call which is not needed.
