I've gotten a call to go out in the morning to a new customer and download a program to an Allen Bradley PLC-3. 3rd-hand intel says:
1. The PLC "Lost it's memory"
2. They have a backup on diskettes
3. They have the programming software on diskettes.
I'm trying to do my homework but it seems this stuff is so old, there is not much info floating around to read. My investigation suggests the correct software is called 6200-PLC3. Correct?
What are the system requirements? I have VMWare but never tried running DOS in it. Do I need an XP VM running a Win 3.1V VM running a DOS box? I don't even know where to start. What version of DOS does it need to be?
What cable do I need? Research suggests 1770‑KF2 which appears to be a box bigger than a phone book (ironic reference to other obsolete thing). Can't I just make a serial cable? I can't find a pinout.
Any pointers greatly appreciated!
Alternatively, if anyone has a speech prepared for "the Big Letdown" where you have to tell a customer that his precious moneymaker has exhausted all 9 lives, I'll take that.
