How to connect the 5 Pin DeviceNet wires


DeviceNet is an industrial automation network used to connect industrial equipment such as sensors, actuators and more complex equipment. DeviceNet uses Controller Area Network (CAN) as its underlying protocol. Its physical layer is usually a five-wire system, including two data lines, one power line, and two public lines


The following is a common DeviceNet five-wire wiring method:


1. Data Lines: DeviceNet has two data lines, usually labeled CAN_H (CAN High) and CAN_L (CAN Low). These two lines are used to transmit data. DeviceNet uses differential signaling, which means that the voltage difference on the CAN_H and CAN_L lines is used to represent the data bits. Generally speaking, CAN_H is connected to the red wire and CAN_L is connected to the black wire.


2. Power Line: This is the power supply line, usually labeled V+. This line provides 24V DC power to the devices on DeviceNet. Generally speaking, V+ is connected to the white wire.


3. Common Lines: DeviceNet has two common lines, usually labeled V- and Shield. V- is the common reference line of the power supply, usually connected to the blue wire. Shield is a ground wire used to shield electromagnetic interference, usually connected to the green wire.
