• Version 1.4 with Instruction List(alpha) released (finally)

  It took a good 8 months, but i finally got a chance to revisit this project since i got to actually deploy version 1.3 with Ladder on a real industrial application-rollerway control! That meant:A. I got to do yet another debugging overhaul, and removed a series of minor, but annoying bugs that made PLCemu practically unusable. Ladder diagrams now work, and work well. B. I got the chance to finish the implementation of a second language! Now PLCemu supports IEC-61131-3 compatible Instruction List. It still has known bugs, and doesn't implement subroutines. Next up- Subroutines Analog I/O USB devices Structured Text language Multitasking Rungs

• v.1.3 released

  after massive debugging and testing, v1.3 beta is available. the editor now is OK, and LD works far better than before. multiple branches etc. work fine. also, operators [,],) for set, reset and negate coil have been added. (check help file and website)

• PLC-EMU BETA release

  LD (with memory stack) and everything else planned has been implemented and (should) work as intended, passing to BETA stage. Please Feel free to test and submit bugs!

• LD works! (well, sort of)

  Yet Another Massive debug. Fixed Makefile for comedi, &compiled & tested plcemu with comedi 0.7.76 on a 2.6.18 kernel, works fine! :) LD language _kind of_ works. It BASICALLY works, but as the memory stack is not properly implemented _yet_, do not expect _every_ and _any_ Ladder diagram to work correctly. However, you can -sort of- program in Ladder now. Up next: Instruction List.

• sorry about that

  i had forgotten some debug related code in the release, which would make it not work as expected. please download again, or wait for the next version which will (hopefully) include LD...

• debugged first alpha version

  fixed C API, which should now work fixed makefile massively debugged. Everything except LD parser should now work fine.

• released first alpha version

  this is a buggy alpha version for testing purposes LD language is not working.
