Generally speaking, after the external alarm information is connected in series, the esp signal is connected to the input port (ESP) of the system, and the peripherals are normally closed point switches, buttons and relay contacts. Usually include: hard limit contact switch, inverter alarm contact, emergency stop button, etc.

If you want to completely shield, you can jump a line to +24V at the esp port. So there will never be an external emergency stop alarm. Of course, some systems can be directly shielded in the machine parameters.
