We have a material loading and blending control system built using proprietary digital and analog I/O boards, 16 position keypad interfaces, and CPU control board manufactured by "Advanced Controls and Measurements, Inc.".
We're in the process of replacing the control systems with ones built around standard A-B CompactLogix PLC hardware.
However, in the mean time I've been asked for options to keep this existing gear in operating condition. I'm not certain of all of the details, but it appears the equipment OEM doesn't have circuit board level drawings or BOMs, but did learn the code running in it was written using the Franklin C compiler.
Several of the PCBs (digital I/O) are fairly straightforward, use parts that are still available, and, except perhaps for the communication interface, look easy enough to repair in-house. The analog input and CPU PCBs are another matter, and it is unclear whether I can get the C programs running in them.
A three part question ...
1). Does the name "Advanced Controls and Measurements" from the Pennsylvania, USA area ring any bells? I can't find anything remotely relevant doing Google searches.
2). Is Franklin still a viable business? I looked at their website, and noticed their latest C compiler runs under Windows 95, 98, and NT, also read a cautionary message about email responses being slow due to excessive spam (from June 2005), and their latest price list is dated 2001.
3). Does anyone know of circuit board repair companies or similar organizations that specialize is the decidedly unpleasant task of reverse-engineering abandoned systems enough to be able repair and test them?
