- 1756 ControlLogix controllers
- 1768 CompactLogix controllers
- 1769 CompactLogix controllers
- 1789 SoftLogix 5800 controllers
- PowerFlex 700S with DriveLogix controllers You should also understand the following:
- Networking concepts
- RSNetWorx for DeviceNet software

- RSLinx Classic communication software The following chapters describe how to set up a DeviceNet network:
- Chapter 2—Connect a Computer to the DeviceNet Network on page 23
- Chapter 3—Connect Devices to the Network on page 73
- Chapter 4—Configure the Network Offline on page 33
- Chapter 5—Configure the Network Online on page 33 You are not required to complete all tasks in each chapter in the exact order presented to set up your DeviceNet application. For example, you can configure your network offline before you connect a computer to the network. However, there are some requirements related to the order in which you complete tasks. For example, you must complete the tasks in chapters 2 and 3 before you can configure the network online. The following table describes optional and required conditions to consider when determining the order in which you plan to complete tasks in your DeviceNet application. Network Configuration Tasks Task Optional Conditions Required Conditions Connect a computer to the network • Can be completed before or after connecting devices to the network

Chapter 1 DeviceNet Overview
There are disadvantages to using a single network for your DeviceNet application:
- The network must use shorter distances from one end to another.
- The more devices on the network, the slower the overall performance of the network.
- Your network may have more power supply requirements than can be handled by one network
- A single network can contain only up to 64 nodes A subnet configuration is a main network that is connected to distributed subnets using a scanner, or linking device. In this option, you must install a ControlNet network or EtherNet/IP network, also known as a backbone, that connects to distributed subnets using a linking device. For example, if you choose an EtherNet/IP network backbone, you must use 1788-EN2DN linking devices to connect the subnets. The following graphic shows a subnet network.
There are advantages to using subnets for your DeviceNet application:
- Typically, there are shorter runs on subnets, which allow a faster communication rate for the DeviceNet network.
- With fewer devices on each subnet, the overall performance of the network is faster.
- There are simpler power requirements. There are disadvantages to using subnets for your DeviceNet application:
- The overall cost to install the network is higher than using a single network.
- You must manage multiple networks.
- The Logix5000 controller is remote from the linking device. For example, with subnets in a 1768 CompactLogix application, a 1768-L controller is remote from the 1788-CN2DN linking device. The DeviceNet scanner connects a Logix5000 controller to the devices on a DeviceNet network. The following graphic shows how a scanner exchanges data between a controller and devices on the DeviceNet network.

Logix5000 controllers can usually communicate with devices on other networks with no additional configuration or programming. A bridge connects two networks. IMPORTANT (^) You cannot bridge from a device on a DeviceNet network to a device on a ControlNet nor EtherNet/IP network. You can only bridge from devices on ControlNet or EtherNet/IP networks to devices on DeviceNet networks. Refer to table Bridging Across Networks on page 17 for more information. The bridge is one of the following:
- A single device with communication ports for two different networks, such as a 1788-EN2DN linking device
- A separate communication device in the same chassis For example, the bridge device shown in the following graphic is connected to both EtherNet/IP and DeviceNet networks. Device 1 on an EtherNet/IP
Bridge Across Networks
Chapter 1 DeviceNet Overview
You must choose a baud rate for the DeviceNet network. There are three rates available for the network:
- 125 kbps—This is the default baud rate for a DeviceNet network. It is the easiest baud rate to use and is usually sufficient.
- 250 kbps
- 500 kbps The following table describes the most common methods to set a baud rate.
Method Description Autobaud feature At powerup, the device automatically sets its baud rate to the baud rate of the first device it hears on the network. The baud rate remains set until the device powers up again. The network requires at least one device with a fixed baud rate so the autobaud devices have something against which to set. Typically, scanners and network interfaces have a fixed baud rate.
Choose a Baud Rate for the
Network
Chapter 1 DeviceNet Overview
Method Description Switches or push button on the device
Some devices have switches or push buttons that set the baud rate as follows:
- The device reads the switch setting at powerup.
- Typically, the switch lets you select either autobaud or a fixed baud rate, that is 125 Kbps, 250 Kbps, or 500 Kbps
- If you change the switch setting, you must cycle power to the device before the change takes effect. There are exceptions. For example, the 1756-DNB module has a push button that only lets you set the baud rate if the module is disconnected from the network or network power is off. Once you change the baud rate, the module automatically resets to the new baud rate. Software Some devices require a programming device to set its address. For example, you can use the computer and the DeviceNet node commissioning tool to set the baud rate of a device. The node commissioning tool is available in either of the following methods:
- Automatically when you install RSNetWorx for DeviceNet software
- As a separate application on the RSLogix 5000 programming software CD, revision 13.0 or later The length of the trunkline and type of cable determines which baud rates you can use.
Baud Rate Maximum Distance Cumulative Drop Line Length
Flat Cable Thick Cable Thin Cable 125K bit/s 420m (1378 ft) 500m (1640 ft) 100m (328 ft) 156 m (512 ft) 250K bit/s 200m (656 ft) 250m (820 ft) 100m (328 ft) 78m (256 ft) 500K bit/s 75m (246 ft) 100m (328 ft) 100m (328 ft) 39m (128 ft) If you change the baud rate of the network, make sure that all devices change to the new baud rate. Mixed baud rates produce communication errors. Complete the following steps to set the baud rate for the network.
- Connect the network interface to the network and set its baud rate.
- Connect the scanner to the network and set its baud rate.
- For each device that has only fixed baud rates ( no autobaud), set the baud rate and connect it to the network.
- Connect the remaining devices to the network and enable autobaud for each of them.
If a device Then has a switch to enable autobaud 1. Set the switch to autobaud.
- Connect the device to the network. does not have a switch to enable autobaud 1. Connect the device to the network.
- Use RSNetWorx for DeviceNet software to enable autobaud.
To communicate on the DeviceNet network, each device requires its own address. In general, a device can use any address in the range of 0…63. However, we recommend that you follow the guidelines in the following table.
