So as my regular
It's not that it's so difficult building a single PLC panel, it's that I'm having to build the panel in a manner such that I can reproduce it again--EXACTLY-- in a couple of months.
Instead of just throwing a power supply and a surge suppression system and an uninterruptable battery back up system into a box with a touch screen PLC and a bunch or wires and DIN rail and terminal strips, I'm trying to in the process develop a whole new product line around the design making room for future options and as yet unknown variations.
I'm basically thinking six months to a year down the road on the calendar and the expandability and future uses are more work than the metal box of wire I'm spending twelve to fourteen hours a day looking at on my workbench.
A lot of people that are not an engineers think that we're all like "The Professor" on the TV show "Gilligan's Island" and that we know everything about anything by the time we finish four years (or in my case ten years full and part time) of college.
I seem to forget that fact myself sometimes when I go out and write a proposal and then manage to get a purchase order for some monstrosity a customer wants to buy.
Thus yet again this morning I'm too mentally tired and lazy to write much of anything beyond what you see here.
Time for a nap I guess before getting up and doing it all over again I guess...
