The basic units have a CPU a computer processor that is dedicated to run one program that monitors a series of different inputs and logically manipulates the outputs for the desired control. They are meant to be very flexible in how they can be programmed while also providing the advantages of high reliability no program crashes or mechanical failures , compact and economical over traditional control systems.
Consider something as simple as a switch that turns on a light. In this system with a flick of the switch the light would turn on or off. Beyond that though there is no more control. If your boss came along and said I want that light to turn on thirty seconds after the switch has been flipped, then you would need to buy a timer and do some rewiring.
So it is time, labor and money for any little change. This is a rather simple example but in a larger system with many switchs and lights and a host of other devices all interacting with each other this kind of flexibility is not only nice but imperitive.
