For Baum bus (If there is a short circuit between the control signal J and power supply terminal of the Baum bus, the module error connector for that Baum bus will be disconnected from the home bus under the interruption action of the overcurrent protection element. This has the advantage that it does not affect the terminal device connected to the 7-wire connector and does not cause the entire system to stop.
