FunctionClosedA function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Format the current date/time to a string.

Inputs

SEL : DINT    Format selector

Outputs

Q : STRING    String containing formatted date or time


  • The real-time clock may not be available on all controller hardware models. Please consult the controller hardware specifications for real-time clock availability.

Remarks

Possible values of the SEL input are:

1           current time - format: 'HH:MM:SS'
2          
day of the week
0 (default)
current date - format: 'YYYY/MM/DD'

In FFLD language, the operation is executed only if the input rung (EN) is TRUE. The output rung (ENO) keeps the same value as the input rung.

ST Language

Q := DAY_TIME (SEL);

Op1: LDClosed"Ladder diagram" Ladder logic is a method of drawing electrical logic schematics. It is now a very popular graphical language for programming Programmable Logic Controllers (PLCs). It was originally invented to describe logic made from relays. The name is based on the observation that programs in this language resemble ladders, with two vertical "rails" and a series of horizontal "rungs" between them SEL
