Hi and thank you for your response.
To answer your question I really do not have a base to work off of. No language knowledge. I started as a maintenance floor supervisor some 40 years ago stayed with the same company. Left as project engineer/ utility manager. Got sent to China for three year so I think I did something right.
When I started with the company A/B just came out with the 20/20 system if if you remember that system. I believe that is correct. Our warehouse conveyor system was design with that system in mind. I have gone to various schools over the year on A/B PLC changes for the company but only to have a knowledge of what the techs were doing and be able to converse with them. No programming or maintenance troubling shooting.
Retired had my own electrical wiring business but after hip (both) and back operations had to get out. Sat home and the mind started to go.
Started doing math problems at home to keep the mind busy then thought about learning PLC work. However I do have a job part time on the weekends, but not real challenging.Oh I am 69, am I told old? I am in good health thank God and I love to work. I want to learn PLC troubling shooting for maintenance and programming. Love the thought of it. Hope I did not ramble on to much, daughter says I talk more not since retirement then ever before.
