GIVEVIS (Statement)
Function
Releases visual process priority.
Format
GIVEVIS
Explanation
This statement releases visual process priority on the µVISION board
optionally installed in the robot controller. With this, another task can obtain

the GIVEVIS command is executed.
If an attempt is made to execute the GIVEVIS command although another task
has already obtained visual process priority, an error will occur.
Note: Robot control priority is automatically released in the
following cases. Therefore, it may be possible to ignore the
GIVEVIS command.
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
