Example:
Function Block Diagram - MAKE_DATE:
The MAKE_DATE outputs a date 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 the day from the D input). On a live system, the inputs for a MAKE_DATE 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:
The syntax for a MAKE_DATE function in an ST Program is:
- Output := MAKE_DATE (Y, MO, D);
Where Output, Y, MO, and D are defined as variables earlier in the ST program.
Alternatively, you can use the following syntax:
- Output := MAKE_DATE (Y:= 2006, MO:= 02, D:= 14);
Where the numbers are the input values (in this case, they are the same numbers as used in the Function Block Diagram example above).
