I've been out of the loop since about mid-January, with only a few brief moments of consciousness about the mail I've received from this project. Now it appears that I may be getting a project that could underwrite a portion of the LinuxPLC development I've wanted to do on my own time, if I ever happened across any time to call my own. Can I bother anyone for a synopsis of any code written for interpreting/compiling and executing ladder logic? Likewise, has anything been coded for creating a ladder file?
I did, many weeks ago, start an algorithm for optimizing the evaluation of ladder logic based on an "optimized" representation of the data. The algorithm is basically based on work done by a close friend who has a Ph.D. in Operations Research with a specialty in the optimization of
fixed-cost networked systems (i.e. cost = time to evaluate each "node" or symbol on a "network" or rung.) He is willing to help me complete the
algorithm, should I find the time.
However, I don't want to rework anything that has been successfully completed. Rewrites can wait til there is viable code in all areas. So,
would someone kindly let me know what has been done, and what is being done in this area?
