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
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. This function can be used instead of SigPlay function block if you want to trigger the signal using a specific timer.
