The machine is running, the mode suddenly switches to "manual" or "homing".

It's a very weird situation

No program was written to switch modes

OES:4.11.1

In order to verify, I unplugged the power supply and communication of the screen, and used remote software to do the control. There was no problem and everything was normal

It was concluded that the problem was in the hardware, the HMI Device, and needed to be replaced

This is also an important point, now through the troubleshooting is the HMI hardware problem
