Introducing the Vision OPLC

Vision OPLCs are programmable logic controllers that comprise an integral operating panel.
Compactly designed, these controllers are compatible with different types of Unitronics' I/O
modules. This allows you to build Vision-controlled systems capable of automating a broad
range of analog and digital applications. All Vision OPLCs offer RS232 communications,
CANbus networking options, and a real-time clock (RTC).
Vision OPLC operating panels contain a graphic LCD screen and a keyboard. Certain models
offer graphic touchscreens. The LCD screen displays operator instructions, alarms, and real-
time variable system information via text and graphic images. The operator uses the
programmable keyboard to enter or modify data within the Vision-controlled system. This
communication interface between the controller and operator is referred to as the HMI, or
Human Machine Interface, throughout this manual.
