(Operator Interface) A low-level graphical interface to a specialized computer on the plant floor such as a programmable automation controller (PAC), programmable logic controller (PLC) or distributed control system (DCS). Typically built into a ruggedized terminal for shop floor use, it provides a remote interface to the push buttons, switches and gauges found on the equipment itself. An OI does not offer the rich graphics and flexibility as do Windows and Mac-based interfaces. Contrast with HMI. See PAC, PLC and DCS.

Origin of oi

  • From the Ancient Greek -οι (-oi), the second-declension masculine nominative plural case ending — the plural form of -ος (-os); compare the equivalents of the Latin second declension (-us), with which the Grecian case endings are usually substituted in English words, especially in the plural.
