Appendix 5 DeviceNet Plug-in – 2080-DNET20
Power Supply
The plug-in module gets its power from the Micro800 backplane. However, the
DeviceNet interface is isolated from the Micro800 system. Therefore, network
power to operate the DeviceNet transceiver on the plug-in module is supplied by
an external DeviceNet power supply.
If using a single power supply in the network, calculate the total current
requirement of all devices in the network and add +10% for current surge.
Recommended power supply is 1606-XLSDNET4.
DeviceNet Baud Rate Switch Definitions
Baud Rate DR (Data Rate) SW1 Switch Position
12
125k OFF OFF
250k OFF ON
500k (default) ON OFF
Autobaud ON ON
For most applications, Rockwell Automation recommends that you use
default node and baud rate settings. The DeviceNet scanner plug-in will
be at node 0 and the devices will be at nodes 1...20. The baud rate will
be at 500k baud and the maximum trunkline length will be 75 m
(KwikLink Lite).
