11.7 Terminating circuit for Devicenet systems
When installing a DeviceNet system, ensure that the terminating circuit of the data lines is correct.
The circuit prevents the occurrence of interference caused by signals reflected onto the data lines.
The trunk line must be terminated at both ends with resistors of 120 Ω each and 1/4 W power loss
(see “Figure 40: Network topology, DeviceNet”).
