D.Station module does not require external power supply since it separately feeds necessary power (self-feeding). In addition, the power lines can be connected like a diagram shown above.
  • Page 44 6 CABLING ②③ Main line and drop line Communication cables connected to the network can be classified into two types. A main line is a bundle of cable having terminating resistor attached at both ends. A cable splitting out from the main lines as well as cables splitting from the drop line is also a drop line.

Particularly, communication lines must be isolated at least 300 mm from power lines for inverters, motors, and power regulators.
  • Page 48: Figure 6-5 Connector Wiring

    6 CABLING (2) Connector Removable connectors are used to connect communication cables to nodes and to branch taps. There are two types of connectors: open and closed. The open-type connectors, particularly plug-type screw connectors, are recommended to connect cables to the D.Station modules and T-branch taps. The plug-type screw connector enables removal of a node without parting the network.
  • Page 49: Figure 6-6 Branch With Branch Taps

    6 CABLING (3) T-branch taps T-branch taps are used to branch a cable from main line and to split drop lines. Two types of T-branch taps are available for the DeviceNet network. The open-type tap is preferably used. In addition, the T-branch taps can be classified into two types: 1-branch and 3-branches.
  • Page 50: Figure 6-7 Branch With Tb

    6 CABLING The communication cables can also be branched by terminal blocks (TBs). Connect each cable wire to the terminal block with an appropriate solderless terminal. See the TB connection example below. V+ (red) Solderless terminal CAN-H (white) Main or Main or drop line drop line V+ (red)
  • Page 51: Figure 6-9 Connection Of Terminating Resistor

    6 CABLING (4) Terminal resistor Both ends of the main lines must always be terminated with a terminating resistor. The physical characteristics of the terminating resistor are as follows: Physical characteristics Resistance: 121 Ω Tolerance: ±1% Permissible loss: 1/4 W Type: Metal film There are many ways to connect terminating resistors but it is recommended to use a terminal block to connect a terminating resistor.
  • Page 52: Figure 6-10 Connection By A Power Tap

    6 CABLING (5) Power supply tap and communication power supply The DiviceNet does not require communication power supply for each nodes because it feeds power directly from cables. Instead, connect a communication power supply rated at 24 V to the main line. LQS070, however, does not use power supply from the network because it has a internal communication power supply except when another node without power supply is connected to it.

  • Page 55: Figure 6-13 Network Grounding

    6 CABLING (6) Network grounding If not grounded, the network may be affected by emission of static electricity and external power noise, resulting in malfunction or, in the worst case, failure of the device. To prevent this, DeviceNet is grounded at a single point. If DeviceNet is grounded at more than one point, a grounding loop may occur.
  • Page 56: Figure 6-14 Uncovering Of Braided Shield

    6 CABLING Another way of grounding is from the D.Station module connected near the center of the network. As the drain terminal of the D.Station module is not grounded, this grounding is done as follows: (1) uncover the braided shield of the communication cable, (2) solder a ground wire to it, (3) attach an M3 solderless terminal to the free end of the ground wire, and (4) connect the solderless terminal to the cable shield connection terminal on the mount base of the D.Station module.
  • Page 57: Restriction Of Cable Lengths

    6 CABLING 6.1.4 Restriction of cable lengths The lengths of cables in DeviceNet are restricted. Satisfy the following restrictions when cunstrucing a DeviceNet. (1) Maximum network length The maximum network length means a distance between two nodes or terminating resistors which are located furthest from each other. It is dependent of the type of the main line cable and the transfer rate of the network, See the figure below.
  • Page 58: Figure 6-17 Example Of Branch Length

    6 CABLING (2) Branch length The branch length means a distance between a point at which a drop line branches out from the main line to a point at which the end of a drop line. The maximum branch length is 6 meters. The maximum length of a power cable from the main line is 3 meters.
  • Page 59: Figure 6-18 Example Of Total Branch Length

    6 CABLING (3) Total branch length The total branch length represents the sum of lengths of all branch cables in the network. It does not represent total lengths between each node and the branch tap of the main line. Maximum likelihood of total branch length differs depending on transfer rate of the network.

  • Page 61: Consideration On Disposition Of A Communication Power Supply

    6 CABLING 6.1.5 Consideration on disposition of a communication power supply In the DeviceNet network, each node is supplied power from a 5-wire communication cable through a communication connector. Therefore, check whether each node can be supplied power from a planned power supply disposition independently of the cable length restriction (see Section 6.1.4) when constructing the network.
  • Page 62 6 CABLING Furthermore, the maximum current capacity of a drop line becomes smaller as the drop line becomes longer, which is true to both thick and thin cables. The maximum current capacity I (a total amount of currents consumed in the branch) of a branch can be calculated by equation below.
  • Page 63: Table 6-5 Maximum Length Of Main Line (Thick) And Maximum Current

    6 CABLING ● Replace the thin cable (when it is used) with a thick cable and achieve the higher maximum current capacity of the cable. ● Move communication power supply towards the center of the main line so that the nodes are located at both sides of the power supply.

  • Page 69: Grounding Specifications

    6 CABLING 6.1.6 Grounding specifications The transmission path must be grounded at a single point. Therefore, always insulate the communication section of a node which is connected to the transmission path and ground the node at one point only. When two or more power supplies (individual power supply or network power supply) are used, select one of the power supplies in the network, and ground the drain and the V-power line of the transmission line through it as shown below.

    7 COMMUNICATION FUNCTION 7.1 Function Overview As a process communication (I/O communication) function, the D.Station supports slave-style polling communication only. It does not support bit-strobe/change-of-state/cyclic communication or peer communication. The term "process communication" refers to a communication method for transmitting/receiving control data. Table 7-1 shows the polling communication specifications.

    7 COMMUNICATION FUNCTION 7.2 Service Communication Function The D.Station use explicit communications to receive service requests from another node. When a requested service is addressed to an object within the D.Station, the it executes the service and transmits a response. Other nodes (master) are able to receive the results by requesting required services using this explicit communication.
