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.
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).
