1. The motherboard cannot recognize/display the peripheral devices. 2. The peripherals will stop working for a few seconds or more. 3. A slow boot may indicate that your motherboard is broken, although it could also be other components. 4. The touch screen does not recognize the flash drive, or ...

1. Observational method As the name suggests, it is to use the eyes to visually check whether the components are burned, damaged, deformed, discolored, cracked, and whether the CRT filament is lit after the current is turned on.

1. The touch all-in-one machine can carry out the dynamic display of the three-dimensional model of the object, and has a good interactive experience function. The audience can operate by themselves through the touch all-in-one machine, and "touch" the object at zero distance on the screen, and the audience can also rotate and zoom in arbitrarily on the touch all-in-one screen.

1) Check if the hard drive is turned off in the "Display Energy Saving Settings" of Wlndows 9x. The way to do this is to right-click on the desktop, select the "Properties" command, then select the "Screen Saver" tab from the dialog box, click the "Settings" button, and set the parameter to "...

The man-machine interface is connected to programmable controllers (PLCs), frequency converters, DC governors, instruments and other industrial control equipment, and the display screen is used to display and write working parameters or input operation commands through input units (such as touch screens, keyboards, mice, etc.) to realize the interaction of human and machine information.

30. Button control indicator (same address) Set the multi-state transfer switch element/bit state transfer switch element and the multi-state indicator element/bit status indicator element to the same address, click the multi-state transfer switch element/bit state transfer switch element, and the corresponding indicator ...

When the HMI communication failure is caused by on-site interference, the following methods can be used to troubleshoot the fault: The communication line adopts shielded twisted pair cable, and the shielding layer needs to be grounded at one end, that is, only one end of the PLC and the touch screen can connect the shielding layer to the ground horn (it is recommended to connect it to the HMI end of the 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 ...
