A PROGRAMMABLE
LOGIC CONTROLLER (PLC)
is an industrial computer control system that continuously monitors the state
of input devices and makes decisions based upon a custom program to control the
state of output devices.
Almost any production line, machine function, or
process can be greatly improved using this type of control system. However, the
biggest benefit in using a PLC is the ability to change and replicate the
operation or process while collecting and communicating vital information.
Another advantage of a PLC system is that it is
modular. That is, you can mix and match the types of Input and Output devices
to best suit your application.
While Ladder Logic is the most commonly used PLC
programming language, it is not the only one. The table lists of some of
languages that are used to program a PLC.
Ladder Diagram (LD) Traditional ladder logic is
graphical programming language. Initially programmed with simple contacts that virtual
the opening and closing of transmits, Ladder Logic programming has been
expanded to include such functions as counters, timers, shift registers, and
math operations.
