DC/DC converters and optocouplers in the fieldbus interface provide electrical
isolation between the CANopen bus system and the electronics.
The cable shield must be applied to the CAN shield. This is terminated to ground
in devices with 1 MΩ (DIN rail contact). A low-impedance connection of the
shielding to ground is possible only from the outside (e.g., by a supply module).
We recommend using central ground contacts for the entire CANopen bus line
shielding.
To minimize reflection at the end of the line, the CANopen line must be
terminated at both ends by a cable termination.
Attention - bus termination!
The CANopen bus segment must be terminated at both ends!
No more than 2 terminations per bus segment may be used!
Terminations may not be used in stub and branch lines!
Operation without proper termination of the CANopen network may result in
transmission errors.
