Function - Get a point from a "Signal" resource


ID : DINT    ID of the signal resource, provided by SigID function
IN : TIME    Time (X) coordinate of the wished point within the signal resource


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


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.
