PLC can be ___________ in plant to change the sequence of operation.only programmedonly reprogrammedprogrammed and reprogrammedable to give a set point

The correct option to fill in the blank is: programmed and reprogrammed.

Explanation

A Programmable Logic Controller (PLC) is an industrial digital computer designed for the control of manufacturing processes, such as assembly lines, or robotic devices. One of the key features of PLCs is their versatility. They can be programmed to create specific control sequences to operate machinery and processes based on input signals and predefined conditions.

However, as processes evolve or change, it is also essential to be able to reprogram the PLC to adapt to new operational requirements or to optimize performance. The ability to change the sequence of operation through programming and reprogramming grants operators flexibility and control over the production processes, enhancing efficiency and accommodating various operational needs without the need for physical alterations to the control hardware.

Thus, the best choice reflects the full capacity of a PLC in adapting to different requirements: it can be programmed and reprogrammed.
