Video: How to Program a TON Timer in RSLogix 500
Written by Neal Babcock
Let’s say we have a rotating beacon that is mounted near a conveyor. For safety purposes, the beacon turns on when the conveyor is running to let the plant personnel know that the conveyor is operating.
Everyone agrees it would be better if the beacon came on for 5 seconds before the conveyor starts.
The conveyor is automatically started from another section of the plant.
We want the beacon to turn on as soon as the run command is given.
However, we need to delay the start of the conveyor for 5 seconds after the run command has been given. That way, the beacon will be on for 5 seconds before the conveyor starts.
We will do that with a TON (Timer On Delay) instruction. Watch the video to see how.
