Use digital inputs to choose inquiry sequence?

[Rick H.]

Hello,

Is it possible to use a couple of the NI-1456 CVS TTL Digital Inputs to select which specific Inquiry Sequence should be ran?

I currently own NI Vision Builder for Automated Inspection.  I do not own LabView.

I am using a NI-1456 CVS and firewire camera.  My solution will use the NI-1456 CVS stand-alone.  It will not be connected to a VGA monitor, or to a computer.  I intend to use the system to detect flaws in silicon wafers.  Due to several possible wafer sizes and shapes, I will have to develop an Inquiry Sequence for each wafer type.  I would like to have the NI-1456 CVS unit contain several Inquiry Sequences.

Hi Rick -

Actually, this is a very commonly used feature of VBAI!  From the Configuration Interface, choose Tools»Configure Inputs/Outputs.  This will pop up a settings window for the entire inspection process.  The second state (called "Change Inspection?") allows you to configure a Product Selection port.  The digital byte written to this port will determine which inspection script to run.  From the listbox, you can choose NI CVS/IMAQ IO Product Selection to use your CVS's digital input port for this feature.

More information about this feature can be found int he NI Vision Builder for Automated Inspection Configuration Help, under the following index: Vision Builder AI Tools»Configuring Inputs/Outputs»NI CVS-1450 Series I/O.  Note that the ISO inputs are used for this feature, not the TTL inputs.
