Rockwell Automation 1738-ADNX ArmorPoint I/O DeviceNet Adapters - Manual (Page 18)

Publication 1738-UM001A-EN-P - February 2005
2-2 What Is the ArmorPoint DeviceNet Adapter?
Use the Adapter The adapter resides on the primary DeviceNet network and the
Subnet simultaneously.
The adapter interfaces between DeviceNet devices and ArmorPoint
I/O modules. The graphic below shows the adapter on the DeviceNet
network and PointBus.
After you have installed your adapter into a ArmorPoint I/O system,
you must perform the following tasks:
1. Set Subnet/Backplane Baudrate
2. Set Subnet/Backplane I/O Module Addresses
3. Configure the Subnet I/O
4. Configure the Primary DeviceNet Network
The steps mentioned above are explained briefly here and then in
greater detail throughout this manual. You must complete the steps for
the adapter to work with DeviceNet masters (e.g., 1756-DNB) on the
primary network and Subnet modules.
IMPORTANT
The PointBus maintains all DeviceNet network
protocol but also offers configuration capabilities.
