Chapter 21 Vision Control (Option)

21-77

Note (1): If the model to be registered is not more than 16 pixels inside

from the edge of the screen, it cannot be registered.

Note (2): The reference coordinates are used to designate a point to

detect when a model is searched.

Note (3): A registered model requires a certain amount of brightness

distribution. If the brightness distribution is too flat or there

are many small differences in the model, it cannot be

registered.

Note (4): If you designate a number already registered, it overwrites the

already registered model.

Note (5): You can find the availability of registration by using

VISSTATUS after the instruction is executed.

Note (6): When this command is executed, the process screen 3

(VISWORKPLN 3) is used as a work area and data on the

process screen 3 are not guaranteed. Also, you cannot use

the process screen 3 for processing.

Note (7): For this instruction, a µ

µµ

µVision board (option) is required.

Note (8): During execution of this instruction, do not power off the

controller. If you do so, the controller will recognize in the

next powering-on sequence that it has not been normally

terminated, so it will initialize the vision-related information.
