Telemecanique Tsx 17 Programming Software ~upd~ -

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 

Key technical notes

• Memory: many TSX 17 CPUs have limited RAM (example: 24 KB program RAM, ~2 KB data) with battery-backed retention; external cartridges for program backup are supported.
• I/O: typical micro-PLC configurations include 12 isolated 24 VDC inputs and a couple of relay outputs on compact models.
• Indicators: front-panel LEDs indicate I/O states, BATIBUS status (DEF, NET, DATA, ON) and can display contents of SW16 if configured.
• Power supply: variants exist with 110–240 VAC input or 24 VDC versions; check the specific model datasheet before wiring.

For critical infrastructure still running on TSX 17, your long-term strategy must be migration. But for short-term maintenance, emergency debugging, or simply recovering a lost program, mastering this legacy software is an invaluable skill. Keep a vintage laptop alive, treat your dongle like gold, and remember: the machine doesn't know it's obsolete. telemecanique tsx 17 programming software

Note on Compatibility:

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

1. Insert Disk 1 and run SETUP.EXE.
2. Choose Typical Installation (approx 15MB space).
3. When prompted, select your COM port (usually COM1).
4. The installer will ask for the dongle. Plug it into LPT1 before the next screen.
5. Enter the serial number (usually found on the CD sleeve—common master keys: TSX 17-20 or PL7-17-001).
6. Complete installation and restart Windows.

The TSX 17 programming software is a Windows-based application that allows users to create, edit, and execute PLC programs. The software is designed to work with the TSX 17 PLC range, including the TSX 171, TSX 172, and TSX 173 models. The software provides a user-friendly interface for programming, debugging, and testing PLC applications. For critical infrastructure still running on TSX 17,

• Processor: Intel 8086 / 286 / 386 (recommended 486 or higher for larger programs)
• RAM: 640 KB (conventional memory) + EMS/XMS for larger projects
• Storage: ~2 MB free (program itself), plus floppy drive for program transfer
• Operating System: MS‑DOS 3.3 – 6.22 (Windows 3.1 could launch a DOS box, but direct hardware access was unreliable)
• Communication: RS‑232 serial port (COM1 or COM2) with a TSX 17 programming cable (Telemecanique ref. TSX PCX 1031 or equivalent, often a null‑modem cable with specific pinout).

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