DeviceNet Network Installation Checklist
If you are setting up your DeviceNet network or it is not working properly go through the following checklist. It will fix your problem 95% of the time.
- Termination resistors. ( 1 at each end of trunk ).
- Grounding of Network. ( One location only ).
- Cumulative drop line budget in spec. for selected baud rate.
- Trunk as linear topology. No Star off of trunk > 20 feet ( 6 m ).
- Spacing guidelines from AC cables.
- No Drops > 20 feet (6 m).
- Trunkline budget in spec. for baud rate.
- Total Network Current Check ( DeviceNet Assistant )
- Common Mode Voltage Check at network ends, with full load.
- Voltage and Ohm readings of CAN wires within spec.
