Before Schneider Electric fully absorbed Telemecanique, and before Modicon became the flagship PLC brand, there was the TSX 17 series. Released in the late 1980s and popular throughout the 1990s, the TSX 17 (often referred to as the "Micro" or "Premium" depending on the specific model) was a compact, rugged PLC used extensively in material handling, packaging, and simple process control across Europe and beyond.
Today, many of these units are still running—tucked away in dusty cabinets, controlling critical machinery in plants that refuse to upgrade. If you’ve inherited one of these systems, finding and using the correct programming software is a significant hurdle.
Let’s be realistic. Running TSX 17 software on a modern Windows 10/11 PC is a journey into pain. Here’s the community-sourced approach: telemecanique tsx 17 programming software
If you have a working TSX 17 system and a functional programming setup: . Keep that vintage laptop and cable in a locked drawer. Document the program. The TSX 17, when working, is nearly indestructible. But the software ecosystem is a museum piece.
Unlike modern unified environments (like Schneider’s EcoStruxure or Siemens TIA Portal), the TSX 17 world is fragmented. There are three primary software packages you need to know about: If you’ve inherited one of these systems, finding
Do not buy expensive "genuine" cables from eBay—they are often just standard null-modem cables. The TSX 17 uses a 25-pin SUB-D on the PLC side (TER port) and 9-pin on the PC side.

If you are starting a new project or have a failed TSX 17: migrate. Use a modern Schneider M221 or M241 (EcoStrucure Machine Expert) and rewrite the logic. The cost of downtime chasing a DOS software issue far exceeds the hardware upgrade.
Yes, but it's manual labor. You can export the ladder logic from PL7-17 as a text file ( .TXT or .LAD ), then import it into Schneider’s older or Unity Pro using a translation tool. However, I/O addressing (e.g., %I0.1 , %Q2.3 ) will need to be remapped. Many plants choose to leave the TSX 17 running as an "island" until failure.
