A Control System is the electronic equipment needed to control a particular pro-
cess. It may include everything from a process control computer, if one is used,
to the factory computer, down through the PCs (and there may be many of them
networked together) and then on down through the network to the control com-
ponents: the switches, stepping motors, solenoids, and sensors which monitor
and control the mechanical operations.
