Math & Logic Tools - Variables

The Variables Math & Logic Tool defines integer, floating point or string values that may be input to the job from an external device; these values can then be referenced by other Location or Inspection Tools or external devices, such as a PLC or a VisionView® Operator Interface Panel.

The Variables Math & Logic Tool is useful in situations where you want to input a value to a Location or Inspection Tool from an external device, like a PLC, or as a value in a Math Math & Logic or Group Math & Logic Tool Expression. For example, if you had an application where you wanted to input a text string for a Read Text Identification Tool, an integer value to control the number of blobs that a Blobs Counting Tool searches for, and a floating point value as a part of the execution formula for a Group Math & Logic Tool, those values can be created in the Variables Math & Logic Tool and then symbolically referenced by the other tools or in the Communications Step.
