Configuring the DeviceNet Network
DeviceNet Online Tab
The DeviceNet Online Tab is available to the user when PowerTools FM is online with the
Ei-DN. This tab displays DeviceNet specific diagnostics and allows the user to view the
status of the DeviceNet network.

Information
Master MacID
The Master MacID is the MacID of the DeviceNet master to the Ei-DN.
Counters
Transmit/Receive Counter
The Transmit and Receive Counters note the successful data packet exchanges between the
Ei-DN and its DeviceNet master.
Bus-Off Counter
The Bus-Off counter counts the number of bus failures in order to safeguard against a network
that goes down. A Buss Off may occur due to errors in wiring, baud rate settings, or MacID
errors on the network. Ten bus-offs in a row initiate the bus-off interrupt (major fault). This
information is used for troubleshooting the Ei-DN
.
