Go to www.schneiderautomation.com where you can download a functional DEMO copy of ProWORX NxT. This Windows program will let you program the entire family of Modicon Micros (the original stuff, not the new Telemecanique MICROs) in their native 984 Ladder Logic language. Its got great documentation, thorough help files, helpful configuration tools/wizards, and even a control drawing generator that takes your documentation and the PLC's "Traffic Cop" and combines them into a DXF CAD file! Stay away from the new 32-bit version 'cause it has great potential but lacks the maturity of X.2 software ;-)
PL7 is for the TSX MICRO and TSX PREMIUM PLCs only. It will not do the older Modicon Micro (the 110CPU part number mentioned above is a Modicon Micro, not a TSX Micro).
Acceptable softwares are:
Modsoft (Modicon DOS based, dead product)
Graysoft (third party, dead product)
Fastrak
ProWORX NxT
ProWORX 32
You can download a demo of FasTrak's programming software for this processor at www.fast-soft.com. A "lite" version of this software is available which supports the Micro processors.
