Embodiment Construction
[0029] The RS485 layout network controls the normal operation of each 485 device, and the RS485 bus / node protector provides an independent protection mechanism at the node of each 485 device to prevent any device in the network from failing. Respond to protect other devices in the network from being affected.
[0030] Each device in the RS485 network is equipped with an RS485 bus / node protector to monitor the working status of the 485 device in real time, using millisecond-level bus detection and quick response. When the 485 equipment is abnormal, check the abnormality for 5 times in a row, immediately and automatically cut off the connection between the current equipment and the bus, and protect the 485 bus from short circuit due to equipment abnormality. When the fault is eliminated, the connection of the device will be automatically restored.
[0031] The RS485 bus / node protector adopts industrial-grade design inside, the maximum power consumption is less than 60mW, suppor...
