Welcome aboard BigJohn.
I've had some PLC experience in my career path as well. They called us Automation Engineers at Dexter Shoe Company where I worked from 1998-2002. Most of my work consisted of gutting Italian shoe manufacturing equipment, looking at the schematics to figure out what they were doing and converting the whole business using Allen-Bradley PLC gear. Intersting and challenging work, and I learned to 'read' Italian.
Again...welcome.
