In the typical Control System example shown above, a PC controls the move-
ment of the workpiece bed across two horizontal axes using Limit Switches
and Servomotors to monitor and control movement.
The PC is the part of the Control System that directly controls the manufac-
turing process. According to the program stored in its memory, the PC ac-
cepts data from the input devices connected to it, and uses this data to moni-
tor the controlled system. When the program calls for some action to take
place, the PC sends data to the output devices connected to it to cause that
action to take place. The PC may be used to control a simple, repetitive task,
or it may be connected to other PCs, or to a host computer in order to inte-
grate the control of a complex process.
