Using Input Points for Triggering Acquisition
Hardware input points located on the DIO board may be specified in the
Visionscape Acquire Step to trigger acquisition. Acquisition can be
specified on either the leading edge or trailing edge of a pulse. If the
Visionscape PCIe IO boards are used in this manner the following
procedure must be observed.
If leading (low-to-high, rising) edge triggering is specified the trigger
1.
signal must be wired to one of the lower 8 input points (I-00 to I07) in
the diagram above – IN0 to IN7 in Visionscape
If trailing (high-to-low, falling) edge triggering is specified the trigger
2.
signal must be wired to one of the upper 8 input points (I-10 to I-17) in
the diagram above – IN8 to IN15 in Visionscape.
This constraint is only applicable to Input points used as triggers in the
Acquire or the Digital Input Step. The Digital Input Step will report the
state of all 16 inputs at the time that it is called if no Data Valid signal is
assigned.
