• Ladder Logic Editor + Simulator
  This program is the answer to your EEE44 needs. What I like about it, is not only that you can keep track of the states ot the internal relays, but also that your working environment is in ladder diagram form. Making it very user friendly. But best of all: its FREE! Download it from TRiLOGI software or directly from this site through the links below.
