As Windows 95 and Windows NT took over industrial computing, Telemecanique (now Schneider Electric) began consolidating its software portfolio. The direct replacement for PL707 in the Windows environment was XTEL.
However, there is a critical nuance: XTEL was designed primarily for the TSX 07, TSX 37, and TSX 57 (Premium) series. While XTEL claimed backward compatibility with the TSX 17, the reality was frustrating.
As the TSX 17 is an End-of-Life (EOL) product with no manufacturer support, facilities still running this hardware face significant obsolescence risks.
The Telemecanique TSX 17 is a legacy programmable logic controller (PLC) that relies on DOS-based software for configuration and programming. Because these tools were developed for 16-bit environments, running them on modern computers requires specific hardware or virtualization. Primary Programming Software
The software package used depends on the specific model and hardware configuration of your TSX 17 unit:
PL7-1 (Part No. TSXLPL71V5E): Designed for base models like the TSX 17-10 or TSX 17-20 without a cartridge. It primarily supports Instruction List (IL) and some Ladder Logic. PL7-2 (Part No. TSXLPL72V5E): Used for the Go to product viewer dialog for this item.
or higher models equipped with a PL7-2 software cartridge. This version expands capabilities to include Grafcet (SFC).
PL7-12 (Part No. TSXLPL712V5E): A combined package that supports both PL7-1 and PL7-2 environments. Core Functionalities
The software suite provides the following essential tools for maintaining legacy systems:
Application Development: Creating programs using Ladder Diagram (LD), Instruction List (IL), or Sequential Function Chart (Grafcet/SFC).
Project Tasks: Organizing logic into specific execution areas, such as the FAST task (a timed subroutine) or MASTER tasks (scanned before/after SFC).
Diagnostics & Maintenance: Online monitoring of I/O modules, communication setup, and program upload/download to the PLC. Hardware & Connectivity Requirements
Connecting to the TSX 17 requires a proprietary hardware setup because the PLC uses an RS485 communication link. For PLC range TSX17 , Can I make a backup of the software? telemecanique tsx 17 programming software
Programming a legacy Telemecanique TSX 17 requires specialized DOS-based software and specific hardware connections, as this PLC has been obsolete for over 15 years. Software Requirements
The software you need depends entirely on your specific hardware model: PL7-1: Used for TSX 17-10
and some 17-20 models. It supports Instruction List (IL) programming.
PL7-2: Required for TSX 17-20 models, typically if a specific PL7-2 software cartridge is plugged into the front. This allows for Ladder (LD) and Grafcet (SFC) programming.
Operating Environment: These programs run on DOS (ideally versions 5.x to 6.22). Modern users often run them via DOSBox or on old Windows 95/98 machines. Connection Hardware
To link your computer to the PLC, you cannot use a standard cable: Programming Cable: Part number TSX17ACCPC is the official cable required to connect the TSX 17 to a PC.
Signal Converter: The connection is an RS485 link, so an RS232/485 converter is necessary if you are building your own interface. Handheld Options : Alternatively, you can use the T317 handheld or T407 programming console found on secondary markets like eBay. Program Structure & Logic The TSX 17 uses a specific task-based structure: For PLC range TSX17 , Can I make a backup of the software?
Telemecanique TSX 17 is a legacy micro-PLC range that primarily uses
software for programming. Because this system is discontinued, current support and software are primarily maintained through the Schneider Electric Support FAQ Software Versions
The appropriate software depends on the specific hardware model and whether a language cartridge is installed: Control.com PL7-1 (Part No. TSXLPL71V5E): models. It supports Instruction List (IL) language and simple single-task structures. PL7-2 (Part No. TSXLPL72V5E): units equipped with a PL7-2 language cartridge . It adds support for Ladder (LD) (Sequential Function Chart) programming. Combined Package (Part No. TSXLPL712V5E): A legacy bundle that supports both PL7-1 and PL7-2. Schneider Electric System Requirements & Connectivity Operating System: These packages are
. They are officially unsupported on Windows 2000, XP, or newer versions. Running them typically requires a dedicated DOS machine or a DOS emulator (like DOSBox). Programming Cable: You must use the TSX17ACCPC
cable to connect the PLC to a computer's serial port. An RS232/485 converter may be necessary depending on your PC's hardware. Hardware Cartridges: The TSX 17-20 requires a specific module (e.g., TSX P1720FA As Windows 95 and Windows NT took over
) to unlock PL7-2 capabilities. Programs can also be stored on EEPROM/EPROM cartridges for backup. Schneider Electric Legacy Support Resources
Detailed technical characteristics and installation procedures are available via the TSX 17 Micro-PLC Installation Manual Troubleshooting:
Diagnostic LEDs on the unit (RUN/STOP, CPU/PROG, IO/MEM, BATT) indicate the PLC's state; a blinking RUN/STOP LED usually means the program is intact but the PLC is stopped.

Here is the story of the Telemecanique TSX 17 , a legend from the MS-DOS era of industrial automation.
Imagine it’s the early 90s. You’re on a factory floor, carrying a "luggable" PC that weighs more than a small child. To talk to the TSX 17, you aren't using USB or Ethernet; you're hunting for a specific RS232/485 converter cable (the elusive TSX17 ACC PC ) just to get a handshake. The Tale of Two Software Paths
Programming a TSX 17 was a "choose your own adventure" dictated by the hardware in front of you: The PL7-1 Path: For the standard TSX 17-10, you lived in the world of
. It was a lean DOS application that didn't require a dongle but restricted you to simple Instruction List (IL) Ladder Logic The PL7-2 Path: If you were lucky enough to have a TSX P1720FA module plugged into the front, you unlocked . This was the "pro" tier, requiring a physical but granting access to
(Sequential Function Chart) and more advanced word operations. The "DOS" Reality
Running this software today is a trip back in time. It doesn't play nice with modern hardware—you can't just open it on Windows 11. It was designed for DOS 4.0 or 5.0 . In fact, if your computer's CPU is faster than
, the timing loops in the software might break, making communication with the PLC nearly impossible. Engineers still tell stories of rolling out dusty PCs with dot matrix printers
still attached just to pull a backup from a machine that hasn't been touched in 30 years.

The primary programming software for the legacy Telemecanique TSX 17 PLC series is PL7-17 (or PL7-07 for micro versions), a DOS-based application. Depending on the specific hardware and language requirements, users typically require PL7-1 or PL7-2. Core Programming Software Options Don’ts:
Selecting the correct software version depends on your TSX 17 model and the programming languages you intend to use.
PL7-1 (Part No. TSXLPL71V5E): Used for the TSX 17-10 and base TSX 17-20 models. It supports Instruction List (IL) and, in some cases, limited Ladder Diagram (LD) logic. It is designed for single-task software structures.
PL7-2 (Part No. TSXLPL72V5E): Required for the TSX 17-20 when a TSX P1720FA software cartridge is installed. This version unlocks more advanced capabilities, including Grafcet (sequential function charts) and expanded Ladder Diagram support.
PL7-4: A Windows-based version (often compatible with Windows NT/98/XP) sometimes used for later TSX 171 models. Hardware and Communication Requirements
Programming a TSX 17 requires specific physical interfaces to bridge the gap between a PC and the PLC's proprietary port. What is the pinout for the TSX 17 plc programming cable?
