Rockwell Automation 2080 Micro800 Digital and Analog Plug-in Modules - Manual (Page 50)

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.
If two or more power supplies are connected to the Kwinklink lite media (trunk
cable) V+ should be broken between the two power supplies.
IMPORTANT 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).

TIP Grounding the network
If grounding at only one location, it is recommended that you ground at the
center of the network.
