Telemecanique Tsx 17 Programming Software Patched

The Telemecanique TSX 17 is a legendary piece of industrial history. Though it was eventually succeeded by the Modicon and Magelis lines after Schneider Electric acquired Telemecanique, thousands of these micro-PLCs are still humming away in factories globally.

If you are tasked with maintaining, troubleshooting, or upgrading one of these systems, the biggest hurdle is usually the software. Here is a comprehensive guide to the Telemecanique TSX 17 programming software landscape. 1. The Primary Software: PL7-1 and PL7-2

The TSX 17 series primarily runs on the PL7 family of software. Depending on the complexity of your unit (TSX 17-10 or TSX 17-20), you will likely encounter two versions:

PL7-1: Designed for the TSX 17-10 (the basic micro-PLC). It uses a simplified instruction set, often focused on boolean logic and basic timing/counting.

PL7-2: Required for the TSX 17-20. This version supports more complex operations, including analog processing and advanced data manipulation.

The Catch: This software was designed for MS-DOS. It is not a modern "point-and-click" Windows application. To run it on a modern PC, you will typically need a DOS emulator like DOSBox or a virtual machine running a legacy OS like Windows 95/98. 2. Alternative: The FTX 117 Dedicated Terminal

Before PCs were standard on the factory floor, programming was often done via the FTX 117 handheld terminal.

It features a small liquid crystal display and a membrane keypad.

It is incredibly durable and doesn't require "booting up" a computer. telemecanique tsx 17 programming software

If you find one on the used market, it is often the most reliable way to make quick logic changes without worrying about software driver compatibility. 3. Connection Requirements: Cables and Converters

You cannot simply plug a standard USB or Serial cable into a TSX 17. The PLC uses a proprietary 8-pin mini-DIN port (often labeled "AUX" or "Terminal").

Original Hardware: You would traditionally use the TSX PCX 1031 (RS232 to RS485) cable.

Modern Workaround: Many engineers now use USB-to-RS485 converters specifically pinned for Telemecanique. Be aware that the TSX 17 uses a specific communication protocol (Uni-Telway), and getting a generic USB adapter to "talk" to the PL7 software through a virtual COM port can be finicky. 4. Programming Languages Supported

The TSX 17 software generally supports two main methods of programming:

Ladder Diagram (LD): The most common graphical language, mimicking electrical relay circuits.

Instruction List (IL/Statement List): A text-based, low-level language similar to Assembly. This was often used on the handheld terminals because it didn't require a large screen to visualize rungs. 5. Challenges in the Modern Era

If you are looking to download the software today, you should keep the following in mind: The Telemecanique TSX 17 is a legendary piece

Availability: Schneider Electric has long since moved the TSX 17 to "End of Life" status. Official support is minimal, and the software is often found in legacy archives or through specialized industrial automation forums.

Data Backups: The TSX 17 uses internal RAM backed by a battery. If that battery dies and you don't have a backup of the program saved via the PL7 software, the PLC becomes an expensive paperweight. Always upload and save the program before attempting any hardware maintenance.

Hardware Expansion: The TSX 17-20 allows for cartridge expansions (EEPROM or EPROM). If your system uses these, you may need a specific burner or the PL7 software to "burn" the logic onto the chip for permanent storage. Summary: Should You Upgrade?

While the Telemecanique TSX 17 programming software is functional, it is a "legacy" experience. If your TSX 17 is part of a critical production line, most experts recommend using the software to perform a final upload/documentation of the logic and then migrating to a modern PLC, such as the Schneider Modicon M221. This allows you to use the modern, free EcoStruxure Machine Expert - Basic software, which is Windows-native and significantly easier to manage.

Option 3: Virtual Machines (VMware or VirtualBox)

Running Windows 98 or Windows XP as a VM on modern hardware.

• Pro: Excellent file management (share folders with the host).
• Con: USB-to-serial passthrough is notoriously unreliable. A VM often drops bytes, corrupting the PLC program transfer.
• Best for: Offline editing and printing documentation, not online changes.

Option 2: DOSBox (The Hacker's Choice)

Open-source emulators like DOSBox and DOSBox-X can run PL707 remarkably well on Windows 10/11. Option 3: Virtual Machines (VMware or VirtualBox) Running

• Steps: Install DOSBox, mount a folder as your C:\ drive, copy the PL707 files, and map a virtual COM port to a physical USB-to-serial adapter.
• Caveat: Timing is critical. The TSX 17 expects precise serial timing. Many users report "Checksum Error" when downloading. You may need to tweak core=dynamic or adjust cycles.

XTEL’s Compatibility Issues with TSX 17

• Limited Language Support: XTEL translated TSX 17 programs poorly. Grafcet sequences (SFC) often broke during import.
• No Live Debugging for TSX 17: You could transfer a program, but online monitoring was unstable.
• Complex Setup: XTEL required a "Unitelway" driver (a proprietary communication protocol from Telemecanique) that was notoriously difficult to configure on modern COM ports.

Verdict: While some engineers successfully used XTEL as a file converter (to migrate TSX 17 projects to TSX 37 or Premium), it was never a reliable runtime programming solution for the TSX 17. For true programming and debugging of a TSX 17, you needed PL707.

Part 4: How to Connect to the TSX 17 PLC

The software is useless without a physical connection. Here is the anatomy of a working connection.

Hardware Required:

1. TSX PCX 1131: The classic programming cable (RS-232 to 8-pin mini-DIN).
2. TSX SCA 115: An adapter for the older 25-pin SUB-D connectors on very old PLCs.
3. Homemade alternative: A null-modem cable wired specifically for Pin 2 to Pin 3, Pin 3 to Pin 2, Pin 5 to Pin 5, plus a loopback on the PLC side (pins 4 & 6 jumpered, pins 7 & 8 jumpered).

Connection Protocol (PL7-17 for Windows):

1. Power down the TSX 17 PLC.
2. Connect the cable to the "TER" (Terminal) port on the PLC. Do not use the AUX port.
3. Power up the PLC. Ensure the green "RUN" LED is either on or off (not flashing red).
4. Open PL7-17. Click "Online" > "Connect" .
5. The software will ping the PLC. If successful, you will see a dialog box showing the Firmware version, RAM size, and I/O configuration.
6. You can now:
   • Upload: Transfer PLC program to PC (File > Transfer > PLC to PC).
   • Download: Transfer PC program to PLC (Caution: This overwrites the machine logic).
   • Monitor: Watch ladder logic execute in real-time.

Troubleshooting "No Response" errors:

• Issue: Timeout error. Fix: Lower your PC's CPU speed (use MOSLO or disable cache in BIOS).
• Issue: Checksum error. Fix: Your cable is too long (keep under 15 meters) or you have a ground loop.
• Issue: Dongle not found. Fix: The parallel port must be set to ECP or Bi-directional in BIOS.

3. System Requirements (Historical Context)

To run the native programming software for a TSX 17 today, the following legacy environment is typically required:

• Operating System: MS-DOS 6.22 or Windows 95/98 (Running in "Real Mode" or MS-DOS prompt). Running PL7-2/3 on modern Windows (10/11) 64-bit systems usually requires a Virtual Machine (e.g., VirtualBox or DOSBox).
• Hardware Interface: A standard RS-232 Serial port (DB9) or a high-quality USB-to-Serial adapter.
• Connection Cables:
  • The TSX 17 CPU usually features a round, 8-pin DIN connector (labeled "TER" or "AUX").
  • Required Cable: TSX SCP 111 (RS-232 / Current Loop adapter) or a custom-wired pinout converting the DIN port to a PC Serial port.

1. Executive Summary

The Telemecanique TSX 17 series is a range of compact programmable logic controllers (PLCs) manufactured by Telemecanique (now part of Schneider Electric). The programming software for this platform, primarily known as PL707 (or PL707 Junior), was a DOS-based integrated development environment (IDE) used to write, edit, compile, and transfer ladder logic and instruction list programs to TSX 17 PLCs. This software is now obsolete, and its operation requires legacy hardware (e.g., a PC with a real serial port and DOS environment, or an older terminal like the XBT‑K).
