After you have installed your adapter into a H Series Fieldbus I/O
system, you must perform the following tasks:
1. Set Subnet/Backplane Baudrate
2. Set Subnet/Backplane I/O Module Addresses
3. Confi gure the Subnet I/O
4. Confi gure the Primary DeviceNet Network
The steps mentioned above are explained briefl y here, and then
in greater detail throughout this manual. You must complete the
steps for the adapter to work with DeviceNet masters (e.g. Rockwell
Automation 1756-DNB) on the primary network and Subnet modules.
