Grouping
Use this item to group products, for example, on lines where many types of products are conveyed. Register
the image pattern to be used as the reference for grouping products as a model beforehand. Up to 64 models
can be registered. The No. of the model that resembles the input image the most, the correlation indicating how
much parts resemble each other and the position of the measurement object can be output.
This item is not provided for the ZFX-C10/C15.
• With the grouping function, registration of models is not executed even if automatic setting is performed. When a
color camera is connected, only automatic setting of color filters is performed.
• Functions equivalent to grouping can also be achieved by the "IMAX" and "IMIN" functions in expressions.
