Accuracy: Accuracy can be defined as the maximum positioning error in a predefined touchscreen area, measured in the straight-line distance between the actual position of the finger and the measured position. When measuring accuracy, a simulated or mechanical finger is used. Place your finger in an exact position on the panel and compare your actual position with the measured position. Accuracy is very important, and users expect the system to accurately find the position of their fingers. One of the most criticized drawbacks of resistive touchscreens is their low accuracy, which diminishes over time. The precision of capacitive touchscreens has created many new applications, such as virtual keyboards and handwriting recognition without a stylus. Figure 1 shows a structurally incomplete touch panel that shows a wandering finger position, when in fact the finger is moving in a straight line.
Finger spacing: Finger spacing is defined as the shortest distance on the screen between the center points of the two fingers as the touchscreen controller measures the position of the two fingers. Finger spacing is measured (Figure 2) by placing two analog or mechanical fingers on a panel and gradually closing the two fingers closer together until the system detects that both fingers are one finger. Some touchscreen vendors refer to the distance between the edges and the center point. The 10 mm finger spacing of a 10 mm mechanical finger indicates that multiple fingers are touching the screen, or that the distance between the fingers is 10 mm, depending on the specification of the touch controller. Without good finger spacing, you can't design a multi-touch solution. Finger spacing is especially important for emulated keyboards, as finger spacing on the screen is usually very short when using emulated keyboards.
Response time: Response time is defined as the time between a finger touch event on the touchscreen and an interrupt signal generated by the touchscreen controller. The measurement method is to electronically touch an environment that simulates a finger touchscreen, or to move an analog finger over a panel. Response time is especially important because it directly affects how quickly a user can move their finger across the screen; pan or flick the action; Write on the screen with your finger or pen. Touch panels with slow response times may have short pauses and no movement detection.

How to correlate the variable in the Kunlun through state with the input port x in the Mitsubishi PLC
1. Offline programming mode: the programmable logic controller and the programmer share a CPU, and when the programmer is in programming mode, the CPU only provides services for the programmer and does not control the field equipment. After completing the programming, the programmer switches to the running mode, and the CPU controls the field device.
