Issue

Invoking the ActiveX zTrigA or zTrigB calls always returns a zero, irrespective of the actual result.

Workaround

You can monitor the actual result in one of two ways. In your RPvdsEx circuit:

  1. Link the output of the TrgIn component to a digital output on your device. This will allow you to view the trigger result on the front panel of the device.

  2. Link a parameter tag to the output of the TrgIn component. You can then read this tag using RPcoX's GetTagVal method.
