Use the methods shown below to connect the Terminating Resistors to the
trunk line. Refer to 2-4-8 Connecting the Terminating Resistors (Terminators)
for wiring details.
1. Connect a Terminating Resistor to the Tap when there is a T-branch Tap or
2. The Terminal-block Terminating Resistor method can be used when a
3. Use this method when there is an Environment-resistive Slave at the end
4. Use this method when using Flat Cable.
Use any one of the methods shown below to ground the network by connect-
ing the cable’s shielding to an acceptable ground (100 Ω or less.) Ground the
network at one point only.
Refer to 2-4-9 Grounding the Network for wiring details.
Always use DeviceNet cables that meet all DeviceNet specifications. The Net-
work may not operate properly if other cable is used.
Refer to the home page of the ODVA for information on DeviceNet cables
other than the ones listed above.
