must set a different address.If the devices are with the same address, it may not be found by communicator,then a separate connection is required to modify the polling address of the device.HART protocol defines the communication mode of multiple devices connected in the same loop as multi-point communication mode. The current of the loop is no longer 4-20ma, but the sum of the output current of these devices. -
