What changed
GetParamto return the actual parameter value instead of a boolean result.uint16_tparameters (port / ref related).Why
GetParamwas incorrectly treated as a success flag, so the real value was never returned.While fixing this, incorrect
uint16_tusage was also discovered and corrected.Compatibility
No breaking change.
On success: returns a number.
On failure: returns the Snap7 error code (same as before).
