Function Block Diagram - NOW:
A NOW function can be used as an input for other functions, for example, as an input for an ADD_DT_TIME function. The NOW function provides the current date and time.
ST Program - NOW:
The syntax for a NOW function in an ST Program is:
Output := NOW();
The NOW function can also be used in place of a Date and Time Input in an ST Program:
Output := ADD_DT_TIME (NOW, Input 2);
Where Output and Input 2 are defined as variables earlier in the ST program. The NOW function replaces Input 1 (it provides the current date and time for Input 1).
