Figure 2.3 Linear topology of the CAN-bus network
In the CAN-bus network, shielded wires are often used for interconnection, so as to enhance the
anti-interference ability. However, there are many types of shielded wires and field wiring is complicated.
Therefore, the wiring diagrams of different types of cables in application are shown below, including the
connection diagrams of double-core single-layer shielded wire, double-core double-layer shielded wire, and
three-core single-layer shielded wire (The "equipment iron shell" in the pictures refers to the outer shell of the
device, which is grounded by default). Regardless of the type of cable, reasonable changes must be made
according to the complexity of the field wiring. Ensure the reliable grounding of the single point of the shielded
wire or ground wire at any time, and carry out on-site wiring in strict accordance with the wiring specifications to
minimize communication errors and abnormalities, and improve the communication quality and service life of the
bus.
