SigScale

Function A 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. - Get a point from a Signal resource.

Inputs

ID : DINT ID of the signal resource, provided by the SigID function.

IN : TIME Time (X) coordinate of the wished point within the signal resource.

Outputs

Q : REAL Value (Y) coordinate of the point in the signal.

Remarks

• The ID argument is the identifier of the signal resource.
  • Use the SigID function to get this value.
• This function:
  • Converts a time value to a analog value such as defined in the signal resource.
  • Can be used instead of the SigPlay function block to trigger the signal using a specific timer.

Op1: LD "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     IN
