Final answer:
A programmable controller can directly monitor and display motor parameters such as speed, temperature, and current draw.
Step-by-step explanation:
A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes.
It can directly monitor and display motor parameters such as speed, torque, current, voltage, power factor, and temperature.
These controllers are an integral part of industrial automation systems and are used to control machinery by monitoring inputs and outputs.
In the most basic terms, a programmable logic controller (PLC) is a computer with a microprocessor but has no keyboard, mouse or monitor. It is essentially built to withstand very harsh industrial environments. It is a distinctive form of computer device designed for use in industrial control systems.
PLCs can also help in diagnosing issues by tracking and recording data over time, which can be crucial for preventive maintenance and troubleshooting.
