Weiluntong touch screen - the reason for the black screen of the industrial touch screen

1. Dispose of dirt and grease on the touch screen The accuracy of the screen is a characteristic of grease build-up on the surface, which can make it cumbersome to type the correct commands. In addition, due to the accumulation of dust caused by overheating, the internal components of industrial computers may not work properly. The use of microfiber ...

The five-wire resistive touch screen and the four-wire resistive touch screen both adopt the principle of analog resistance, and their conventional fault characteristics are exactly the same as those of the four-wire resistor. If you are using a five-wire resistive touch screen, when there is an installation and maintenance problem, please determine and solve the problem in the following order. ...

Try pressing other buttons or areas on the touchscreen to see if you can enter the menu settings interface. 3. If you are using third-party software or ...

1. Check that the power cord is plugged in and if there is electricity. If there is no electricity, you can replace the cord or plug. 2. Check if the power switch is on. If it doesn't turn on, you can try turning on the power switch. 3. Check if the battery is charged. If the battery is low ...

cMT3151 can be stored in the form of data streaming, avoiding the SD card or USB when storing data due to falling off and unable to produce a complete storage record; At the same time, the abnormal operation of the machine is recorded, and the user is assisted in tracking and analyzing the source of the problem. cMT-iPC15 Built-in Error Correction Code (ECC) ...

Touch screen mobile phone capacitive touch screen and resistive touch screen are mainly different in touch sensitivity, accuracy, cost, multi-touch feasibility, damage resistance, cleaning, and sunlight visual effect. Touch sensitivity, 1. Resistive touch screen: pressure is needed to make all layers of the screen ...

1. Generally, in the lower right corner of the touch screen, there is a small black arrow button, click and enter the correct password, you can enter the system settings. However, when configuring, you can disable this button in the software system settings. 2. Set the system bit LB-9020 in the touch screen to ON...

1. The infrared touch screen does not need touch pressure, it can be operated freely even if you wear gloves, and anything can be touched. 2. Compared with the display equipped with capacitive and resistive touch screen, the picture saturation is richer and the contrast ratio is better, which improves the user's visual comfort. ...

1. Check the hardware connections: Make sure the touchscreen is properly connected to the device and that all cables and connectors are in working order. Check if the connector is loose or damaged, and if so, reconnect or replace the connector. 2. Check the drivers: Make sure the device is properly installed.

1. Can the human-machine interface be connected to the PLC? That's not true. Human-computer interface products are produced to solve the human-computer interaction problem of PLC, but with the development of computer technology and digital circuit technology, many industrial control equipment have serial communication capabilities, so as long as there is ...

An overview of the principles To complete multi-touch on the capacitive screen, it relies on adding electrodes of mutual capacitance, in short, the screen is divided into blocks, and a group of mutual capacitance modules are set up in each area to work independently, so the capacitive screen can independently detect the touch status of each area.

Open the Veriton touch screen programming software, select [Common] in the main interface and open it In the Common drop-down menu, select System Parameters and click Open. Then select [HMI Attributes] in the pop-up system parameter setting menu and click OK. ...

1.1 How to delete the job button on the taskbar of the touch screen? Set "Modify/Set System Parameters/General/Job Buttons/Features" to "Closed". 1.2 What does RS485 Default/RS485 2W/RS485 4W Separation mean in the communication port type? r ...

1. Press the "Menu" button to enter the menu interface. 2. Select the "Picture" option to enter the screen settings interface. 3. In the screen settings interface, find the "Copy" option and press the "Enter" key to enter. 4. In the "Copy" option, select "Copy...

There are 2-4 hidden DIP switches on the back of the VIRONT touch screen, and each HMI backplate has a set of reset buttons and DIP switches that can be used to trigger the corresponding function when switching between different modes. The following is a list of categories: mTV series 　　cMT-SVR series 　　If cMT-SVR ...

1. First of all, open the created Weilun touch screen project, select Common in the menu bar and click Open. 2. Secondly, select the system parameter icon in the common drop-down menu and click to open. 3. Finally, click Change. ...

Since the launch of the cMT-SVR, the innovative body and screen separation architecture has subverted the market's imagination of HMI. With the continuous cultivation of Weiluntong, this unique detached HMI has gradually gained a foothold in the market and is now widely used in the market. 　　In order to meet the needs of the new generation of industrial Internet of Things ...

1. Surface acoustic waves are not interfering with other electronic devices. Because only the superficial surface of the screen has ultrasonic waves with a frequency of 5MHz, there will be no interference with other electronic devices. 2. The length of the serial port cable (touch screen to PC). The serial cable can theoretically reach a transmission distance of 15M, ...
