1. Determine the Baud Rate Required for the Application
Refer to the section on communications timing in the Master Unit Manual
(see below) to determine the appropriate responsiveness and baud rate for
your application.
• CS/CJ Series DeviceNet Operation Manual (W380)
• CVM1/CV DeviceNet Master Unit,
C200HX/HG/HE DeviceNet Master Unit Operation Manual (W379)
• DeviceNet PCI Board Operation Manual (W381)
2. Determine the Cable Layout and Cable Lengths to All Nodes
Verify that the planned configuration is within the network configuration
specifications.
• Refer to 2-1 Network Configuration Overview for details on the network
configuration.
• Refer to 2-2 Network Configuration for configuration precautions.
3. Determine the Communications Power Supply Method
When planning the communications power supply layout, verify that the
voltage drop over the communications cables is within specifications.
• Refer to SECTION 3 Communications Power Supply Methods for de-
tails.
• In particular, refer to 3-2-1 Communications Power Supply for a flow-
chart that will guide you through the selection process.
4. Select the Required Devices

ters, Slaves, and the Configurator.
• Refer to 2-3 Cables, Connectors, and Related Devices for details on
other related devices.
5. Purchase the Required Equipment
6. Construct the Network
Construct the network using recommended wiring and noise-control tech-
niques.
• Refer to 2-4 Wiring Methods for details on wiring.
• Refer to 2-5 Minimizing Noise in the Network for details on noise-con-
trol techniques.
• Refer to 2-2 Network Configuration the Network Configuration for other
precautions.
