FAQ

Question?

What programming software and cable are required for the TI 164?

Answer: This PLC series predates modern software and typically requires specialized, DOS-based programming software and a proprietary serial communication cable. These are not included and would need to be sourced separately from legacy automation suppliers.

The battery change date is from 1988. Does the internal battery still hold a charge for program retention?

Answer: It is highly unlikely that the original battery is still functional. For reliable program retention during power loss, the internal battery should be replaced with a new, compatible type before being put into service.

Can this PLC's I/O be expanded, or is it a fixed-I/O unit?

Answer: The TI 164 is a fixed, block-style PLC. It does not support external I/O expansion modules. The 44 inputs and 26 outputs are the total capacity of this specific controller.
