"AdvancedParameters.EventSourceParID" is used to notify the function block of the source of the signal that should be used to capture the registration mark position. If the registration mark sensor is connected to the trigger 2 input of the axis, for example, then the ACP10PAR_STAT_TRIGGER2 ParID must be used.
Information:
For the "AdvancedParameters.EventSourceParID" input, only ParIDs whose data type is INTEGER are allowed (no float values).
The registration mark position captured on the drive depends on the settings in "AdvancedParameters.SignalEdge". The registration mark position can be applied during the contrast transition on the rising edge (mcP_EDGE) or falling edge (mcN_EDGE).
If width monitoring is enabled ("AdvancedParameters.MaxWidth > 0"), mcMIDDLE (detection of the time average value between the rising and falling edge) is also possible.
A tolerance can be defined for the width of the registration mark by setting "AdvancedParameters.MinWidth" and ".MaxWidth" in order to prevent false triggering when multiple signals occur within the expected window (width evaluation).
A window for valid signals can be defined around the expected position ("Configuration.RegMarkPosition") using "AdvancedParameters.WindowNeg" and ".WindowPos". These values can be specified symmetrically (both values the same) or asymmetrically (values not the same).
The window can be used to filter invalid registration mark signals from the sensor, for example, if multiple contrast differences are detected by the sensor within one product interval (text, symbols, etc.).
The window should not be defined as too small since this could cause the registration mark to quickly fall outside of the expected window when dealing with larger material tolerances. However, it should not be defined too large either since the valid registration mark cannot be determined until the end of the expected window (when width evaluation is used).
If the values for the window are set to "0", then the window is disabled and all registration marks will be accepted. However, this should only be defined for free-standing registration marks.
Information:
If width detection is used, then the window must be defined large enough or disabled (value = "0") so that the two edges are located within the window. Otherwise, the registration mark will be considered invalid.
