Hitec touch screen boot test

Storage humidity between 10%-90% Temperature -20°C-60°C If the ambient conditions exceed or approach the critical value, condensation will occur inside the display. The power transformer and other coils inside are also prone to leakage when wet, and may even cause a short circuit in the wiring. If you find that the obvious ...

There are two recommended ways to set up the alarm display on the touch screen: 1. Place the alarm window in the template, so that when the alarm occurs, no matter which screen the alarm window is on, it will automatically pop up, so that the operator can obtain the alarm information. ...

The two-layer transparent metal layer of the four-wire resistance analogue technology operates with a constant voltage of 5V on each layer: one vertically and one horizontally. A total of four cables are required. High-resolution, high-speed transmission response. Surface hardness treatment to reduce abrasions, scratches and chemical resistance. With 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) The general requirements of the lightning impulse control system for the industrial touch film screen 1.1. Use the big button as a brief click interface; 1.2. Run your application in full screen; 1.3. Use bright scenery colors (don't use black); 1.4. Make the user touch ...

Shortcoming: 1. Ambient light factor, infrared acceptance tube has the scale of operation between small sensitivity and large illumination, but the contact screen product can not limit the scale of use, from the dark song hall private room to the outdoor use under the high-intensity sunlight on Hainan Island, as a product, it must adapt. ...

Programmable manipulators (PLCs) have always played an important role in the field of industrial field control. With the increase of the country's investment in the water supply profession, the level of automation of water plant operation has been continuously improved, and the use of PLC in the water supply profession has gradually increased. The touch screen is used with the PLC, which makes the PLC ...

1. What is the difference between the human-machine interface and the "touch screen" that people often say? Strictly speaking, the two are fundamentally different. Since the "touch screen" is only a hardware part that may be used in human-machine interface products, it is a replacement for the mouse and keyboard part of the function, the installation ...

The visual system is a rising star in industrial automation, and the demand for work efficiency in modern industrial automation is constantly improving, and the traditional manual detection mode can no longer meet the needs of production. The emergence of machine vision system is a good replacement for cumbersome traditional manual labor.

Touch screen can be divided into resistive touch screen, capacitive touch screen, surface acoustic wave touch screen, infrared touch screen, optical touch screen according to the type of skill, why do large-size touch all-in-one machines use infrared touch screen? Let's take a look at these different touches one by one. ...

Industrial-grade displays are displays that are used in industrial control links or equipment. The key difference between it and civilian or commercial displays is that the chassis planning is generally made of all-steel planning concepts, and the panel is divided into different materials such as iron plates, stainless iron, stainless steel, and aluminum panels. Industrial-grade display ...

1. Whether to select the correct communication protocol (Modbus, PROFIBUS, CANopen, EtherCAT) 2. Whether the communication cable is OK (RS232 RXD TXD GND RS485 A+ B- CANopen CAN_L CAN_H CAN_GND EtherCAT cable) 3. Is the communication parameter correct ...

Due to the large number of noise sources, the contact screen controller needs to be adapted to the different noise sizes and types that exist in the system for a given time. To ensure the highest robustness in noise immunity, the first factor to focus on is the signal-to-noise ratio (SNR). There are a few different features that we can progress through...

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 ...

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). ...

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. 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.

Problem phenomenon: A contact screen has no response after normal use for a period of time after being turned on. Problem profiling and processing 1. Check to see if the hard drive is turned off in the "Display Energy Saving Settings" of Wlndows9x. The way to do this is to right-click on the desktop and select the "Properties" ...

1. In the daily use of the equipment, try to prevent frequent power off and off, and sudden power failure during operation will cause certain damage to electronic components and hard disk errors; In terms of power supply, keep operating in a stable voltage environment, too low voltage, too high voltage will affect the function of the equipment, and will also ...

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 basically the same as that of the mobile phone screen except for special models. Most computer monitors do not contain a touch screen in the display structure.
