10-3 Program examples (shape and positional deviation inspection)
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.
Coordinate (model 0-X): 200.0 to 250.0
Coordinate (model 0-Y): 150.0 to 200.0
Degree of match (model 0): +09500 to +10000
Final output conditions ladder circuit
When the X coordinate, Y coordinate and degree of match are within
acceptable ranges, the auxiliary relay C000 is turned ON.
