More of a story than a question really but here goes...
I have been self employed for 20 years and been programming plc's for 18 years.
The other day I got a call from a new customer hundreds of miles away from my base. (thats a long way away in England)
They had a machine with a mitsubishi plc controlling it and it wouldn't work correctly.
Like they always seem to say ' it was working yesterday fine but today it won't play'
Being so far away, I asked how they got my name thinking it must be from my website. They told me ' from a little sticker inside, behind the programming port flap'.
That suprised me as I knew it must have been more than 12 years ago since I did that program. I got 10 free stickers once from a printer when I ordered some business cards. I only used about 4 and I put them in the programming port.
This machine (a huge baking and tray washing machine) had, had at least three new owners since I did it and all the documentation and drawings had long since been lost. (except the little sticker)
Of course, it was a doddle to rectify, I knew the program and machine inside out even though 12 years had passed.
In fact I was quite suprised and happy really that the program had never been altered from new. I had the old program still stored on a disk and I verified it was exactly the same.
I wish now that I had bought more of those little stickers and put them in every plc project I have done.
Have you ever had a long forgotten plc call you from the past
