ProWORX 32 is the standard software for the following legacy but highly reliable hardware families:

Note: ProWORX 32 does not support the newer Modicon M340 or M580 platforms; those require Unity Pro or EcoStruxure Control Expert. | Item | Specification | |------|----------------| | OS

By the mid-2000s, the automation world was moving toward the IEC 61131-3 standard. Schneider Electric introduced Unity Pro (later EcoStruxure Control Expert) for the new Modicon M340, M580, and Quantum V2.0 PLCs. Unity Pro offered tag-based programming, user-defined function blocks, SFC, ST, and much better memory management.

Schneider officially discontinued ProWORX 32 around 2010, ceasing technical support and new sales. However, they provided conversion utilities to migrate ProWORX 32 projects (.PRO files) into Unity Pro. The conversion was rarely perfect—function blocks might be misaligned, comments lost, or addressing schemes mangled—so many sites chose to keep running ProWORX 32 on dedicated legacy engineering workstations.

ProWORX 32’s primary claim to fame was its support for the Modicon 984 family (including the 984A, 984B, 984-xx5, and 984-xx0 series) and the Quantum family (the first powerful hot-standby PLC for large-scale process control). Later versions added support for the Momentum I/O and even the Compact 984 controllers. Notably, it did not support the older Modicon 584 or 884 without conversion tools, nor did it support the newer M340 or M580 platforms.
