1.What is Control Net? What's the difference from Ethernet?
A: You can think of it as a "special highway" for communication between PLC and HMI devices. It is fast and very stable, and won't get congested. Ethernet is like a "public internet", you can connect anything, but sometimes there is a delay.

2.Is this screen color? How is the effect?
A: It is color, 9 inches in size. However, it is an old model screen and uses STN technology. It can't compare with the current mobile phone screens. The colors are not as bright, the viewing angle is smaller, but it is definitely sufficient for displaying some buttons, data and simple graphics.

3.How to restore it to the factory settings?
A: This needs to be done during startup, through the software, or through specific jumper combinations. The specific steps are a bit complicated. It is best to refer to the manual and don't randomly press buttons.
