Result
You have programmed the motion of the conveyor relative to the position of the light barrier
"LS3".
The motion is started when the light barrier "LS3" is activated. When the target position has
been reached, the bit of the "start_conveyor_2" tag is set at "Done" output, by means of
which the second conveyor can be set into motion.
In the next section you will add more elements to the HMI screen to visualize the execution
of the programmed processes.
