Benefits for Combining Control and Operator Interface

Operator interface and controller display provide many benefits to the industrial computers and systems. They come in two main features. One is to combine PLC with and operator interface terminal to build a unit designed for basic machines. Another one is to marry a PC-based controller to a full featured HMI. By making the PC-based controller to a HMI offering control and operator interface for the most complex machines. For these features, people most likely can find in panel PCs.

O/I (Operator Interface)

First of all, O/I, HMI (Human Machine Interface), and MMI (Man Machine Interface) allow an operator to manipulate or command a machine or process. Nowadays, there are more complex  manufacturing environments than before. With faster machines, stronger power, higher demands with fewer problems, less downtime with increased efficiency. Operator interface might be the good choice for users to use. In other words, operator interfaces are easy to understand and use.

Furthermore, what exactly is operator interface? If one has operated an ATM then she/he is already familiar with the form of O/I. However, in the industrial world, O/I ranges from user-friendly simple keypads with text displays to complicated graphical interfaces. By graphical interfaces, meaning one can draw draw pictures for visualization presentations. Overall, O/I basically represents a graphical interface to a specialized computer. However, an O/I does not offer the rich graphics and flexibility like Windows and Mac-based interfaces. In additions, O/I is typically built into a ruggedized terminal. O/I provides a remote interface through the buttons or switched from the equipment.


People might ask, what is a display controller? When devices generating a video signal, a display controller is the main part of it. In other words, the display controller produce a TV video signal in a video display system. The video display controllers create the timing of the video signals and the blanking period signal. Moreover, display controllers locate in many applications. For example, such as appliances, industrial controls, medical equipments, mobile communication devices or touch screen monitors.

Types of Display Controllers

Speaking of display controllers, there are several different kinds of display controllers. There are video shifters, CRTC, video interface controllers and video coprocessors. First, the most simple type of video controllers, video shifters.

Next, video shifters are either directly or indirectly responsible for the video timing signals. However, they normally do not access the video RAM directly. By gathering the video data from the main CPU and convert the data into video shifter. Second, video interface controllers needs a CRTC embedded in the video controller chip. Moreover, video interface controllers are much complicated compared to other controllers.

Next, CRTC, also known as Cathode Ray Tube Controller, helps to generate and read the video data. Furthermore, generator based on a CRTC chip have a broad area of capabilities. For example, from text-mode to high-resolution mode which supports lots of colours. On the other hand, video coprocessors offer internal CPU for reading and writing the video RAM. Furthermore, video coprocessors also provide the converting the RAM to video signal.


First of all, the term I/O is short for input/output. I/O describes as any program, operation or device transfers data through computer device. Output is for every transfer from one device to another device as input. Furthermore, there are also multiple I/O terminals can be built on the communication devices. In addition, I/O units can be easily added to or removed, which provides the easiest way to maintain. When in computer storage, multipath I/O provides enhanced performance between the CPU in a computer system. By connecting devices and computer system together for a massive storage devices through controller.

Panel PC

With the power of a modern industrial PC and the convenience of a LCD touch screen. The rugged and slim panel PCs provide IP rated, EMI shield and other environmental protection. all-in-one embedded computer, panel PC with reliable, high-performance solutions for various industry. For example, industrials Industries, such as the food industry, automation control, HMI, digital system, military and industry intent of things (IOT) devices.
