15-4 Program examples (shape and positional deviation inspection)

(1) Outline
The positional deviation measurement (one point search) in measurement 0 allows the degree of
match and coordinates to be measured, and the result, OK or NG, is output.

(2) Output conditions and ladder circuit for measurement 0 using camera 1
When the X coordinate, Y coordinate and degree of match are within acceptable ranges, the
auxiliary relay C000 is turned ON.
