WI-GTWY-9-xxx Wireless Gateway
4.13 Fieldbus Configuration – DeviceNet
4.13.1 DeviceNet Introduction
DeviceNet is a broadcast-oriented communications protocol based on the Controller Area
Network (CAN). The physical fieldbus is a shielded copper cable composed of one twisted pair
and two cables for the external power supply. The baud rate can be changed between 125k, 250k,
and 500kbit/s via Configuration Software or DIP-switch.
DeviceNet has a user organization, the Open DeviceNet Vendor Association - for further
information see www.ODVA.org
4.13.2 DeviceNet Address Setting
On a DeviceNet network, each node must be assigned its own unique Mac ID (Node Address).
The Mac ID is a value between 0 and 63 used to identify each node. On the WI-GTWY-9-xxx
DeviceNet module, the Mac ID and Baud rate settings can be set either using a physical DIP-
switch or via the Configuration Software (Fieldbus Configuration page). To use the switch
address settings, the "Enable Switch Address" option in configuration software must be selected,
otherwise switch settings are ignored. We recommend that you do NOT use the DIP switch to
set address/baud rate as switches can be accidentally changed during operation
The DIP-switches are numbered 1 through 8. Switch 1 and 2 are used to configure the Baud rate,
and switches 3 through 8 are used to configure the Mac ID using binary format (see tables below)
