Guys,
What's the difference between S and SJ service cord? Do I need to specify either of these when I am ordering. I am looking to extend power cords on 120V machinery. thanks!

What do you guys think? What is more maintenance friendly Function Block programming or ladder diagram programs.

What is more maintenance friendly: Function Block or Ladder Diagram?

If you were faced with a machine that is down and out, would you rather the PLC program with function block style programming or the good old fashion ladder logic?

What is a gold bonded relay?

Does anyone know the details of a gold-bonded relay? Typically you here of silver contacts and I have to admit I have never seen a gold relay. I have a defective gold-bonded relay and i'm just hoping to replace it with a relay with similar current ratings. Any info would be appreciated.

thanks,
Randy.
