||Maybe you stumbled upon our page, or
maybe you don't know all the acronyms. This could be the
page you need to help you better understand what a PLC is
and what we do.
- PLC - Programmable Logic Controller. An
industrial computer that has inputs and outputs
wired to it, for example switches, valves, pumps,
analog probes, etc. Some of the more common
manufactures of PLCs are Allen Bradley, General
Electric, Modicon, and Siemens.
- MMI - Man Machine Interface. Graphical interface
that communicates with a PLC allowing users to
access PLC functions. A touch screen is one type
of MMI. Another type is a PC running software
such as Intellution, Wonderware, Citect, and
- HMI - Human Machine Interface. This is a more
politically correct substitue for MMI.
