Chapter 7 Configure your Digital Module on an EtherNet/IP Network How to Use This Chapter This chapter describes how a controller controls distributed I/O over an EtherNet/IP network. The controller requires a communication module to connect to the network. Distributed I/O modules require an adapter to connect to the network.
82 Configure your Digital Module on an EtherNet/IP Network are not working but is not required, especially when all connections appear to work normally. When you first install a Rockwell Automation EtherNet/IP module (right out of the box), the module is BOOTP/DHCP enabled. Set Up the Hardware In this example, the Logix5000 controller has an EtherNet/IP communication module to connect to the EtherNet/IP network.
Configure your Digital Module on an EtherNet/IP Network 83 RPIs are only used for modules that produce data. For example a local EtherNet/IP communication module does not require an RPI because it is not a data-producing member of the system; it is used only as a bridge. In Logix5000 controllers, I/O values update at a period that you configure via the I/O configuration folder of the project. The values update asynchronous to the execution of logic.
84 Configure your Digital Module on an EtherNet/IP Network Choose Direct or Rack-optimized Connection The Logix5000 controller uses connections to transmit I/O data. These connections can be direct connections or rack-optimized connections. Term Definition Direct Connection A direct connection is a real-time, data transfer link between the controller and an I/O module. The controller maintains and monitors the connection with the I/O module.
Configure your Digital Module on an EtherNet/IP Network 85 Direct Connections For I/O Modules In this example, assume that each distributed I/O module is configured for a direct connection to the controller. Controller With EtherNet/IP Communication Module Switch EtherNet/IP Network EtherNet/IP Adapters With I/O Modules Digital I/O Modules Analog I/O Modules Digital I/O Modules The following table calculates the connections in this example.
86 Configure your Digital Module on an EtherNet/IP Network Rack-optimized Connections For I/O Modules In this example, assume that each digital I/O module is configured for a rack-optimized connection to the controller. Analog modules must be configured for direct connections.
Configure your Digital Module on an EtherNet/IP Network 87 Ownership In a Logix5000 system, modules multicast data. This means that multiple modules can receive the same data at the same time from a single module. When you choose a communication format, you have to choose whether to establish an owner or listen-only relationship with the module Owner controller The controller that creates the primary configuration and communication connection to a module.
88 Configure your Digital Module on an EtherNet/IP Network Add Distributed I/O To communicate with the I/O modules in your system, you add bridge, adapter, and I/O modules to the I/O Configuration folder of the controller. Within the I/O Configuration folder, you organize the modules into a hierarchy (tree/branch, parent/child). For a typical distributed I/O network you build the I/O configuration in this order.
Configure your Digital Module on an EtherNet/IP Network 89 Add a Module 1. Right-click the level (branch) to which you want to add the module and choose New Module. 2. Choose the module. 3.Configure the module. To Do this Use the default configuration Specify the general information about the module (name, comm format, etc.) and click Finish.

Configure your Digital Module on an EtherNet/IP Network Access Distributed I/O 91 I/O information is presented as a structure of multiple fields, which depend on the specific features of the I/O module. The name of the structure is based on the location of the I/O module in the system. Each I/O tag is automatically created when you configure the I/O module through the programming software. Each tag name follows this format: Location:SlotNumber:Type.MemberName.SubMemberName.
92 Configure your Digital Module on an EtherNet/IP Network Example 1 Example 2 When you choose rack optimization for an I/O module, its tags are created as aliases for the tags of the adapter module. In your logic, you see the tag of the device as aliases for a tag of the adapter module. (The tag name of the adapter is in angle brackets). tag name of the I/O device conveyor:2:I.0
