Teco PLCs can usually be programmed and monitored through RS-232 or USB ports. The specific cable requirements for Teco PLCs can vary depending on the PLC model, connection type, and programming software.

For programming cables, RS-232 cables or USB to RS-232 adapters are typically used for Teco PLCs. These cables provide a serial connection point to the Teco PLC and can be used for programming or monitoring.

Ethernet cables can also be used for some Teco PLC models. An Ethernet cable provides a network connection to the Teco PLC and can be used for remote programming and monitoring.

Choosing the right cable depends on the Teco PLC model, connection type, and programming software. Therefore, before programming Teco PLCs, it is important to review the PLC documentation and technical specifications to choose the correct cable.

Some examples of cables used for Teco PLCs include:

    Teco USB-RS232 programming cable
    Teco T-Box Ethernet programming cable

The specific cable models may vary depending on the Teco PLC model and programming software.
