FAQ

What programming software and cable are required for the TI 140?

The TI 140 series uses proprietary programming software from that era, typically running on MS-DOS. Finding the software and the specific programming cable can be challenging. Please ensure you have the necessary legacy tools before purchase.

Is the memory backup battery still functional?

Given the age (the label indicates a battery date of 1988), the internal battery for program retention will likely need to be replaced. We recommend replacing it upon installation to ensure program integrity.

Can this unit directly replace a newer PLC like a Siemens S7-200?

No, this is not a direct replacement for modern PLCs. The TI 140 has a different programming environment, instruction set, and form factor. Replacing it with a modern PLC would require a complete system migration, including reprogramming and potentially re-wiring.
