Usage Recommendations (continued)
•
Network power configuration
Usage Recommendation
1. Consider not only current capacity of the trunk line but also current capacity of drop
lines when you install a node on a drop line.
2. In particular, when you are connecting nodes in daisy chain on a drop line, be careful
not to have insufficient current capacity.
3. Use a network power whose capacity is much larger than the total current
consumption necessary for the network.

Registering your DN211 module
Usage Recommendation
1. When your DN211 is going to be I/O registered in the T2/T2E/T2N, leave blank for
the slot where the DN211 is installed.
After automatic allocation is performed, the DN211-installed slot is left blank.
4. How to Handle Your DN211 (software)
•
Node address of your DN211
Usage Recommendation
1. Set the node address of your DN211 to a value smaller than the node addresses of
slave devices(because of the feature of CAN currently used in the DeviceNet).

How to solve overrun errors
Usage Recommendation
1. Reduce the network communication speed when an overrun error occurs (500 kbps
-> 250 kbps -> 125 kbps).
