Unitronics’ profound belief in the importance of usability led us to create an industry first: a PLC provided with an integrated operator interface.

The result is a new generation of PLCs :
the OPLC™. Our OPLC™ controller series combine Operating Panels & Programmable Logic Controllers into a single unified device, easy to program and easy to operate.

The M90/M91 and Vision OPLC™ Series are prime examples of the OPLC™ philosophy. Our most recent Vision OPLC™ feature is Ethernet connectivity. Ethernet enables data exchange--PLC-to-PLC, and PC-to-PLC--over an enterprise's existing LAN wiring.

The OPLC™ operating panels contain a display screen & keyboard. The display screen is used to display messages, so that the PLC can communicate with the operator overseeing the automated process. The keyboard is used to enter information into the system & to initiate functions, so that the operator can communicate with the PLC running the automated process. Unitronics’ offers a full line of OPLC™ devices, devices that can handle any automated process. Great ideas always seem so simple...after the fact.
