Precautions for the selection of low-temperature HMI

The light transmittance and clarity of the capacitive contact screen are better than those of the four-wire resistive screen, and of course, it cannot be compared with the external acoustic wave screen and the five-wire resistive screen**. The reflection of the capacitive screen is severe, and the transmittance of the four-layer composite contact screen of the capacitive skill to each wavelength of light is uneven, and there is a problem of color distortion, ...

The interior of the touch screen can be roughly divided into: communication interface unit, driver unit, memory variable unit, and display unit. In addition to the display unit, the other 3 units are invisible to us inside the touch screen. 1. Communication interface ...

1. The difference between human-machine interface and configuration software Human-machine interface products, often referred to as "touch screen", include HMI hardware and corresponding special screen configuration software.

Human-computer interface (HMI), also known as user interface or user interface, is a preface and dialogue interface for transmitting and communicating information between humans and computers, and is an important part of the computer system. It is the preface to the interaction and information communication between the system and the user, and it realizes the internal aspects of the information.

When the contact screen is connected with the PLC, in fact, the memory of the PLC is used, (the contact screen also has a small amount of memory, which is only used to store system data, that is, the screen, controls, etc.), the contact screen and the PLC communication is generally a master/slave connection, that is, the contact screen reads the data from the PLC, and after making a judgment, it is displayed in the display ...

1. Use the big buttons as a simple click-through interface Dragging, double-clicking, scrollbars, drop-down menus, various windows, or other elements will confuse some unskilled users, and will also reduce the user's affinity for the product and reduce its efficiency. 2. Full screen ...

1. Resistive contact screen Analog resistive screen The analog resistive contact screen is what we generally call the "resistive screen", which is a kind of contact screen that uses pressure sensing to operate. It uses two layers of ITO (indium tin oxide) plastic film coated with conductive function, two pieces of IT...

1. Observe the signal indicator of Hitec touch screen, the light flashes regularly under normal circumstances, about once per second, when touching the screen, the signal light is always on, and after stopping the touch, the signal light resumes flashing. 2. If the signal light is not touched, it is still at ...

1: Main interface: interface 1, interface 2, interface 3, interface 4 on the interface separately call out interface 1, interface 2, interface 3, interface 4. 2: Interface 1: Click the left button pointer to configure the control decrement, click the right button pointer to configure the control increment. The number key can be displayed to the value of the numerical configuration control ...

1. Projective capacitive contacts Although the basic structure and working principle of a projected capacitive contact screen is the same as that of a four-wire impedance film, the projected capacitive impedance film does not go through the contact field, but captures the change in capacitance between the electrodes. Generally speaking, when using the form of a capacitive sensor, it can be ...

1. Run your app in full screen Remove the file name bar and menu bar, so you can enjoy the benefits of running the entire screen. 2. Choose bright colors (don't use black) The bright color of the set can hide the finger prints and reduce the dazzling light ...

As an input device, the touch screen has the advantages of easy to use, ruggedness, fast response time, and space saving, and the user can use it directly through the contact screen to complete the operation, without the need for a keyboard or mouse, and is very practical and widely used. ...

1. If it is the first time for the user to use the capacitive contact screen, it is recommended to first follow the detailed device driver in the manual, and then calibrate the screen according to the on-screen prompts. 2. In addition to ensuring the correct device of the system software, remember not to install two or more connections on a host.

Fault phenomenon: A touch screen, its click accuracy decreases, and the cursor is difficult to locate. Fault analysis and processing 1) Run the touch screen calibration program. (Start - Settings - Control Panel - Acoustic Screen ---Capberate Button). ...

Industrial control automation skills are a kind of comprehensive use of control theory, instrumentation, computer and other information skills to complete detection, control, optimization, scheduling, management and resolution planning of the industrial production process, so as to increase output, improve quality, reduce consumption and ensure safety.

Outsiders often misunderstand this kind of term, taking the common computer display screen as an example, it is only a kind of display screen, and its structure is fundamentally the same compared with the mobile phone screen, except for special models Most computer graphics use a display screen structure that does not include a contact screen, and does not have a ...

(1) After the terminal is turned on, find out whether each calibration teaching file is not clicked in the execution step (2) If it exists, perform the step (4); (2) After the boot is finished, the active high-motion is the quasi-program, prompting the user to calibrate the touch screen, after the calibration is completed, the touch screen driver ...

The touch screen senses the contact of our fingers because when the finger touches a specific direction on the screen, it is equivalent to sending a precise electronic signal to the screen. There are many types of contact screens, which are broadly divided into resistive contact screens and capacitive contact screens. Now the most widely used is "electricity...

The touch screen interface is the same as the general interface, in addition to the touch screen interface, other user interfaces include web interface, software interface, game interface and mobile phone interface. Touchscreen interfaces have many similarities with them: Fundamentally, they are all interactive systems, and they are all ...

The four ends of the touch screen RT, RB, LT, LB four poles, all participate in a uniform electric field, so that the lower layer (indium oxide) ITO GLASS is covered with a uniform voltage, the upper layer is the receiving signal device, when the pen or finger presses any point on the surface, at the finger press, the controller ...
