Remarks
VSet is used to set property values for vision sequences, calibrations, and objects from the SPEL
For many vision sequences all the proper property settings will be set from within the Vision Guide
development environment. However, there are also times when you will want to set property values in a
+
SPEL
program prior to running a vision sequence. For example, you may want to set the NumberToFind
property before running a sequence, or maybe you want to use the same vision sequence with 2 different
cameras. Both of these scenarios can be handled in SPEL
Shown below is a Vision Guide program which runs the same vision sequence for 2 different cameras to
calculate the number of holes found in a board.
It is assumed that a Sequence called "FindHoles" has already been created prior to running this program.
FindHoles contains a "Part" Blob object which is configured to find the number of holes in the Search
Window using Holes Result. In this example, we will run the sequence and then display the number of
holes which were found.
When VSet is called from a program, changes are only made in memory and are not saved. After program
NOTE
execution stops, the vision system is restored to the saved state.
