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.

So, How Much Power Could Solar Cells Contribute To The World?
Written by Neal Babcock
Solar cells, also known as photovoltaics, use semiconductor materials to convert sunlight into direct electrical current. As of now, they provide just a small portion of the world’s electricity. Their global generating capacity is about 5000 MW, or only 0.15% of the total generating capacity from all sources. Still, sunlight could provide as much as 4500 times as much energy as the world currently consumes. Read more
