I have the TSX17-20 PLC from TELEMECANIQUE from 1989 year.
I have a problem with SOFTWARE KEY: it is damaged.
It's number is TSX SKC BC 2110 II:10 3982, W9.1291135 01.01.A.01
I can not run the program pl7-2 without this SOFTWARE KEY.
Can anyone help me where can I buy this SOFTWARE KEY or can I run the program without it ?

Best regards,
Kostadinov Nikola

Telemecanique is now part of Groupe Schnieider; you can go to "", and you can look there for the sales office in your country.
As you says this plc is very old, but here in Mexico they still got this part numbers in stock.

By the way; i don´t think you can run the program with out the key.

Are you sure the key is damaged? The key for this software will not work on all PCs, it is especially difficult to find notebooks that it works on. From what I've been told, this key basically sets up an oscillator connected to the parallel port and then the frequency is read from the port, if the port voltage varies due to energy saving techniques etc., or the port is not bi-directional, the key validation will fail. If you haven't already tested your key on a desktop PC, I would suggest you try this first. I also have an old copy of this software with its key. If you find you really do need a replacement software package, you can contact me off list at [email protected].

If I remember correctly, this software had two versions and one of them is without software key. Maybee the guys from Tele. could supply you with the version which does not require a key.
