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

Input	Data Type	Range	Unit	Default	Description
ID	DINT				ID of the signal resource, provided by the SigID function.
TIME	TIME				Time (X) coordinate of the point within the signal resource.

Outputs

Output	Data Type	Range	Unit	Description
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 an analog value as defined in the signal resource.
  • Can be used instead of the SigPlay function block A function block groups an algorithm and a set of private data. It has inputs and outputs. to trigger the signal using a specific timer.

Op1: LD Ladder diagram - This is a method of drawing electrical logic schematics. It is 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
