ProWORX 32: The Definitive Guide to Schneider Electric’s Legacy PLC Software

7.1 Keep-as-is with virtualization (most common)

• Run Windows XP VM on modern hardware.
• Use a Modbus Plus to Ethernet gateway (e.g., Moxa MGate MB3280, Prosoft MVI56) so modern PC doesn't need MB+ card.
• Backup all .PRW and .XIF files plus firmware images of PLCs.

3.3 Communication Protocols

ProWorx 32 communicates over:

| Protocol | Physical Layer | Typical Use | |----------|---------------|--------------| | Modbus Plus (MB+) | RS-485 twisted pair at 1 Mbps | Primary programming & peer-to-peer | | Modbus Serial | RS-232/422/485 (RTU/ASCII) | Direct via CPU serial port | | Modbus TCP/IP | Ethernet (via bridge modules like NOM, BM85) | Modern connectivity | | SA85 (ISA card) | PCI/ISA bus on PC – Modbus Plus adapter | Legacy desktop connection | | PCMCIA MB+ card | Laptop cardbus | Field service |

Where to Find Support and Resources in 2024

Schneider Electric officially ended support for ProWORX 32 several years ago. However, the user community remains active. proworx 32

The Future: Migration Strategies

Every year, maintaining ProWORX 32 becomes harder. Hard drives fail, dongles break, and knowledgeable engineers retire. If your facility still relies on ProWORX 32, consider these three migration paths:

2.1 Evolution Timeline

| Era | Software | Platform | PLC Families | |------|----------|----------|---------------| | 1980s-1990s | ProWorx NxT | DOS | Modicon 984, 584 | | 1995-2005 | ProWorx 32 | Windows 95/NT/98/2000/XP | 984, Quantum, Compact, Momentum | | 2000s-2010s | Concept | Windows | Quantum, Premium, Atrium | | 2010s+ | Unity Pro / Control Expert | Windows 7/10/11 (64-bit) | M340, M580, Quantum (newer), M241 | ProWORX 32: The Definitive Guide to Schneider Electric’s

Path 3: The Hybrid – Communication Gateway

Install a gateway (e.g., Anybus or Red Lion) that allows a modern SCADA system to talk to your old 984 PLC via Modbus. Keep ProWORX 32 for maintenance but modernize the HMI.

2. Programming Languages

While the modern IEC 61131-3 standard includes Ladder Diagram (LD), Function Block Diagram (FBD), Structured Text (ST), Instruction List (IL), and Sequential Function Chart (SFC), ProWORX 32 focused on two: Run Windows XP VM on modern hardware

• Ladder Logic (LD): The primary language. ProWORX 32 offered an exceptionally clean, fast ladder editor. It used the traditional Modicon contact/coil symbols, along with special function blocks like timers (TMR), counters (CTR), one-shots (MCR), and math operations (ADD, SUB, MUL, DIV).
• Instruction List (IL): For legacy 984 systems, ProWORX 32 also allowed programming using the 984-specific mnemonic instruction set, which was sometimes necessary for very old programs or complex math.

Crucially, ProWORX 32 did not offer true SFC or structured text—those came later with Unity Pro.

Core Features of ProWORX 32

Despite its age, ProWORX 32 packed a suite of features that made it highly effective for its time. Many of these features are still respected by veteran controls engineers.
