A pencil manufacturer had an old painting line that needed sharpening.  Their ancient and obsolete PLC was replaced with a compact Allen Bradley Micro Logix brick style PLC.  AC components were replaced with 24VDC versions and a lot of old wiring and components made neat.  A small touch screen reduced physical buttons while providing helpful messages. Since the wiring schematics were long gone, EDC created a fresh set of prints.  Another small job with a big impact.
