4.2.6 Example of using multitask
An example of the multitask execution is given in this section.
(1) Robot work details.
The robot programs are the "movement program" and "position data lead-in program".
The "movement program" is executed with slot 1, and the "position data lead-in program" is executed with
slot 2. If a start command is output to the sensor while the robot is moving, a request for data will be made to
the personal computer via the position data lead-in program. The personal computer sends the position data
to the robot based on the data request. The robot side leads in the compensation data via the position data
lead-in program.
