Sorry, could not help myself.
Click software is a free download, and the hardware is almost free.

Actually all of the A/D software except for DirectSoft is free and fully functional. The latest version of Do-More even has a built in simulator that works like a real PLC and can communicate using your PC ports (I used it to test a serial radio network!) I have not tried to use PSuite simulator for real world comms, but it might also be possible.
So drbitboy, get you some more 'o that free stuff!
