TAKEVIS (Statement)

Function

Obtains visual process priority.

Format

TAKEVIS

Explanation

This statement obtains visual process priority on the µVISION board optionally

installed in the robot controller. Without a µVISION board installed, an error

will occur if the TAKEVIS command is executed.

If another task has already obtained visual process priority and the system

cannot obtain it, an error occurs.

If a task that does not obtain visual process priority attempts to execute a

visual instruction, an error occurs. In a program in which a visual instruction is

executed, visual process priority must be obtained with the TAKEVIS command

prior to the visual instruction.

If a TAKEVIS command is executed in a task with visual process priority or in a

subroutine called from the task, the processing continues without change.

Note: Visual control priority is automatically released in the

following cases.

•

••

• If an END command is executed (Except for an END

command at the end of the program called)

•

••

• If a KILL command is executed

•

••

• If the robot controller is initialized with the teach pendant or

I/O
