Example:
Function Block Diagram - MAKE_DATE_AND_TIME:
The MAKE_DATE_AND_TIME outputs a date time value that is made up from the components supplied via its inputs (the year is taken from the Y input, month from the MO input and so on). On a live system, the inputs for a MAKE_DATE_AND_TIME function are often the results of a calculation, with the inputs being variable depending on the outputs of other functions etc.
ST Program - MAKE_DATE_AND_TIME:
The syntax for a MAKE_DATE_AND_TIME function in an ST Program is:
- Output := MAKE_DATE_AND_TIME (Y, MO, D, H, MI, S, MS);
Where Output, Y, MO, D, H, MI, S, and MS are defined as variables earlier in the ST program.
Alternatively, you can use the following syntax:
- Output := MAKE_TIME_AND_TIME (Y:= 2006, MO:= 02, D:= 14, H:= 12, MI:= 41, S:= 21, MS:= 17);
Where the numbers are the input values (in this case, they are the same numbers as used in the Function Block Diagram example).
