Network Configuration
In order to configure the DeviceNet plug-in and scan the network, you need to 
import user-defined function blocks (UDFBs) in your Micro800 project in 
Connected Components Workbench. Autoscan is used to add nodes into the 
scan list.
Network Wiring
The DeviceNet specifications provide for maximum network distances for the 
main trunk line and drop lines, depending upon the baud rate used on the 
network. 
Module Status Indicator
LED state Module status Description
OFF No power There is no power present.
Flashing Green Operational Unit is starting up.
Green Unit operational Device is operating normally.
Flashing Red Minor fault. A recoverable fault is present or the module is 
undergoing firmware update.
Red Unrecoverable fault. A non-recoverable fault is detected.
Network Status Indicator
LED state Module Status Description
OFF No power or offline There is no network power or device is not operating.
Flashing Green Idle No valid network connection has been made.
Green Online The plug-in module is operating normally and receiving 
messages.
Flashing Red Connection time out One or more network connections has timed out.
Red Critical link failure The plug-in module has detected an error that makes it 
incapable of communicating on the link (Bus Off or 
duplicate MAC_ID). 
It is recommended that when Autoscan is running for the nodes in 
range, or for the connection to be established, the nodes should be idle 
without any pre-occupied connections requests.
