That brings back memories...
I did more work with FactoryLink - in the mid-late 90's I wrote a real-time trending package add on for it, and surprised the FL folks as I figured out how to access the tag database and configure the pens on the fly
WITHOUT a development key
I also did some work with Wonderware, and Fix Demacs (I may have the name slightly wrong on the last one).
Eventually I designed a real time database / SCADA package for the company I was working for at the time, initially for OS/2 which was later ported to NT 3.51 and 4.0. I used WxWindows for the gui widgets, it ported easily.
Also made a bunch of protocol converters, and drivers for the SCADA above.
Modbus & Modbus/TCP were easy, A&B DFK-1 was a bit painful due to escape sequences... the worst was CDC Type-1 RTU
Really off topic here, but I was curious how many people on the forums have used a piece of industrial software called Wonderware (also called Intouch, and Invsys, and ArchestrA...)
I ask because I'm using it right now and fairly pissed off at this piece of tripe that beens forced on our client and was hoping people could join me in some jovial roasting
Ever wonder how they got its name? Back when it was being designed all the beta testers were left scratching their heads going "I Wonder where all my data went?"
