My largest project to date just finally went live today. A Do-More PLC handling a bunch of digital I/O, with a little analogue input, and Serial input. Took advantage of a bunch of the Ethernet functions, and threw in a C-More for good measure. Without the help of folks here and at the AD forum, I would have been lost. Everyone's help, especially with dealing with the Serial Input Protocol portion of this project, was invaluable. I have learned a ton, and realized just how much I love this stuff. Everything is working just as it's has been designed to, and the qualification is swimming right along (finger's crossed for no protocol deviations). Once again thank you. On to the next project, though this one will be much simpler.
