Telemecanique Tsx 17 Programming Software |link| May 2026

To program the legacy Telemecanique TSX 17 micro-PLC, you primarily need PL7-1 (for Boolean/Ladder) or PL7-2 (for Grafcet/List) software. These are DOS-based applications designed for hardware that is now considered "vintage" in the industrial world. 1. Required Software Versions

The TSX 17 range relies on the PL7 family of software. Because these are 16-bit DOS programs, they will not run directly on modern 64-bit Windows systems without emulation.

PL7-1: Used for basic programming using Ladder Logic or Boolean instructions.

PL7-2: Required for more complex applications involving Grafcet (SFC) and advanced data handling.

TSX 17-10/20: These specific hardware models are compatible with the software mentioned above. 2. Connectivity & Cables

Connecting a modern PC to a TSX 17 requires specific hardware conversion:

Cabling: The standard cable is the TSX17ACC8, which connects the PLC's "Console" port (RS-485) to a PC.

Signal Conversion: You typically need an RS-232 to RS-485 converter or a specialized USB-to-TTY/RS-485 adapter compatible with Schneider Electric/Telemecanique pinouts. 3. Running Software on Modern PCs

Since PL7-1 and PL7-2 are DOS-based, you have two main options for deployment:

DOSBox: An emulator that allows you to run DOS software within Windows. You must "mount" your serial port (COM port) within DOSBox to allow the software to communicate with the PLC.

Virtual Machines: Running a 32-bit version of Windows XP or a pure MS-DOS VM can sometimes be more stable for timing-sensitive serial communications. 4. Alternative: The TSX T317 Handheld Terminal

If software is unavailable, the TSX T317 is a dedicated handheld programming terminal. It allows for: Direct entry of Boolean instructions. Monitoring of I/O and internal bits. Simple program modifications without a PC. 5. Transition to Modern Hardware telemecanique tsx 17 programming software

The TSX 17 is obsolete. For long-term reliability, it is highly recommended to migrate to current Schneider Electric ranges:

Modicon M221: Often used as a modern replacement for micro-PLCs.

EcoStruxure Machine Expert - Basic: The free, modern software used to program current micro-controllers, which is much more user-friendly than the legacy PL7 environment.

The Telemecanique TSX 17 is a legacy micro-PLC range originally developed by Square D/Telemecanique (now Schneider Electric). Programming this hardware requires specific legacy software packages and hardware interfaces that are no longer in commercial production . Primary Programming Software

The software required depends on the specific processor module and desired programming language :

PL7-1 (TSXLPL71V5E): Used for basic TSX 17-10 and TSX 17-20 units . It supports Instruction List (IL) language (boolean operations on bits) .

PL7-2 (TSXLPL72V5E): Required for TSX 17-20 units equipped with a standard language cartridge . It supports more advanced programming in Ladder Diagram (LD) and Grafcet (SFC) .

PL7-12 (TSXLPL712V5E): A combined package that supports both PL7-1 and PL7-2 versions .

Handheld Programmers: Devices like the T317, T407, or T607 can be used for direct keyboard entry of code, primarily for PL7-1 modules . Critical System Requirements

Because this software is legacy technology, it has strict compatibility limitations:

Operating System: The software is DOS-based and designed for DOS versions 4.0 or 5.0 . It is not supported on Windows 2000, XP, or newer operating systems . To program the legacy Telemecanique TSX 17 micro-PLC,

Processor Speed: It must not be run on computers with CPUs faster than 500 MHz . Running it on modern high-speed hardware often causes communication timing errors. Hardware Interface & Accessories TSX 17 Micro-PLC Installation Manual - MRO Electric

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

) 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.

Part 7: Migrating Away from TSX 17

If you are reading this article because you cannot find the programming software or the hardware is failing, it is time to consider modernization.

Schneider Electric’s official replacement path is: TSX 17 → Twido (discontinued) → Modicon M221 / M241

Overview

The TSX 17 (TSX T4xx series) is a family of Telemecanique/Schneider Electric micro-PLCs from the 1980s–1990s (examples: TSX T407 / TSX 17B 1428). They include a built-in CPU, discrete I/O, BATIBUS networking on some models, and limited onboard RAM with optional memory cartridges. Programming was historically performed with Schneider’s PL7 family tools (PL7-2 / PL7-2 for TSX/TSX17 series) using proprietary serial programming cables.

Challenge 1: Where to find the software?

Schneider Electric no longer supports or distributes PL7-17. Legitimate copies are gone. Your options:

• eBay / Surplus sellers: Look for "TSX 17 Software Kit" on floppy disks.
• Industrial salvage auctions: Sometimes consultants sell their old laptop with the software pre-installed.
• User groups: PLCs.net, MrPLC.com, or specialized German forums (Telemecanique is huge in DACH region).

Key Features of PL707

• Two Programming Languages: The TSX 17 primarily supported Grafcet (the French standard for sequential function charts, later known as IEC 61131-3 SFC) and Ladder Logic (Contact plan).
• Direct Addressing: Unlike modern tag-based databases, PL707 used direct memory addresses (e.g., %I0.1 for input, %Q2.3 for output).
• Offline Simulation: A rudimentary simulation mode allowed logic testing without a physical PLC.
• Documentation Printing: It could generate printed circuit diagrams and cross-reference lists—critical for pre-digital era maintenance.

Supported software and tools

• PL7-2: Main legacy programming environment used for TSX-series micro-PLCs. Provides ladder and instruction-list style programming and utilities for download/upload, monitoring, and setting system parameters.
• PL7 components: device configuration tools, communication drivers for serial/BATIBUS, and memory cartridge utilities.
• Third-party tools and community resources: scattered manuals, scanned datasheets, and forum posts—useful for pinouts, protocol details, and troubleshooting.

1. PL7-17 (The DOS Standard)

Era: Late 1980s to Mid 1990s Operating System: MS-DOS (5.0 to 6.22) or Windows 95 DOS Box Language: Ladder Logic (Grafect - SFC not fully native)

Key Features:

• Text-based menu system (no mouse support initially).
• Required a physical "dongle" (parallel port key) for full functionality.
• File extension: .PRO or .SEQ.
• Programming via serial COM port (usually COM1 or COM2 at 9600 baud).

Why you might need PL7-17: You have a very old TSX 17-10 with original firmware (pre-1994). PL7-17 is notoriously finicky about CPU speed (needs a slow PC, sub 100MHz).
