NetLinx Open Network Architecture uses DeviceNet, ControlNet, and EtherNet/IP networks which all speak a common language called CIP. This integrated architecture seamlessly connects devices, machines, and business systems. DH-485 is a local area network for factory devices with a maximum length of 4000 feet and transmission rate of 19.2 kbit/s. DeviceNet provides connections between simple devices like sensors and controllers using CIP. Common Industrial Protocol is the common language that provides control, configuration and data collection across the different networks.

1. NetLinx What Networks are Driving Your Plant? NetLinx Open Network Architecture uses open networking technology for seamless, top-floor to shop-floor integration. The networks in the NetLinx architecture — DeviceNet™, ControlNet™, and EtherNet/IP™ — speak a common language called the Common Industrial Protocol™(CIP) and share a universal set of communication services. NetLinx architecture, part of the Integrated Architecture, seamlessly integrates all the components in an automation system from the simplest device to the Internet — helping you to improve flexibility, reduce installation costs, and increase productivity. NetLinx Open Network Architecture enables you to simultaneously control, configure, and collect information at any point.

2. DH-485 Industrial Local Area Network Overview DH-485 is a local area network (LAN) designed for factory-floor applications. DH-485 allows for connection up to 32 devices, including SLC 500 and MicroLogix 1000 controllers, color graphics systems, and personal computers. The DH-485 link together with auxiliary RS-232-C (DF1 protocol) links make up the DH-485 network. With RSLinx software installed on a PC, communication with other nodes on the network is possible. Using SLC 500 Programming Software, program SLC 500 controllers over the DH-485 network. This means that a single PC connected to the network can be used to program all the SLC 500 controllers on the network.

4. DeviceNet™ Providing Users with the Ability to Distribute and Troubleshoot Simple Devices Throughout Their Architectures DeviceNet network is an open device level network that provides connections between simple industrial devices (such as sensors and actuators) and higher-level devices (such as programmable controllers and computers). Uses the proven Common Industrial Protocol (CIP) to provide the control, configure, and data collection capabilities for industrial devices. DeviceNet is a flexible network that works with devices from multiple vendors offering a wide variety of both Rockwell Automation and third party vendor products.

5. DeviceNet features Cost-effective networking solution to simple devices Easily access data in intelligent sensors/actuators from multiple third party vendors Provides master/slave, Change-of-State, and peer-to-peer capabilities Producer/Consumer services let you configure devices, control, and collect information over a single network Improves system integration for both safety and standard applications Reduces downtime with early detection of system performance problems Reduces maintenance costs with diagnostics and automatic device replacement

6. Common Industrial Protocol (CIP) Common Industrial Protocol (CIP) is a major component within the NetLinx Open Network Architecture, and it provides you with four common features: common control services — provides you with a standard set of messaging services for all three networks within the NetLinx architecture common communication services — lets you connect to any network and configure and collect data from any network common routing capabilities — saves time and effort during system configuration because no routing tables or added logic are necessary to move data between networks common base knowledge — reduces the amount of training needed when moving to different networks within the NetLinx architecture by providing similar configuration tools and features

7. ControlNet™ Providing Users with a Robust, Deterministic, and Secure I/O Network for Their Most Challenging Applications The ControlNet network is an open, state-of-the-art control network that meets the demands of real-time, high-throughput applications. The ControlNet network uses the proven Common Industrial Protocol (CIP) to combine the functionality of an I/O network and a peer-to-peer network providing high-speed performance for both functions. The ControlNet network gives you deterministic, repeatable transfers of all mission-critical control data in addition to supporting transfers of non-time-critical data. I/O updates and controller-to-controller interlocking always take precedence over program uploads and downloads and messaging.

8. ControlNet Features Programming, processor-to processor interlocking, and I/O control on the same link without impacting time-critical I/O Media options to fit your application needs including copper, fiber, fiber ring, media redundancy, and intrinsically-safe Improves I/O performance and controller-to-controller interlocking with high-speed data throughput Supports a maximum of 99 nodes, with no minimum distance between nodes Simple and flexible installation options available Access the network from any node for PLC processor programming and troubleshooting Improved network efficiency with Multicast of inputs and peer-to-peer data Deterministic, repeatable transfers of data to/from digital and analog I/O Producer / Consumer services let you configure devices, control, and collect information over a single network

9. EtherNet/IP™ Frustrated with different networks for business, office, plant floor and everything in-between? Want to control your machinery, supervise your factory, manage your enterprise and surf the Web with just one network? Take the next step in achieving your goals with EtherNet/IP. EtherNet/IP (Ethernet Industrial Protocol) is an open industrial networking standard that supports both real-time I/O messaging and message exchange.

10. EtherNet/IP Features Widely available Rockwell Automation and 3rd party products and services worldwide Flexible speeds to support both 10 and 100M bit/s products View control information from anywhere, anytime from a standard Web browser using products with built-in Web server capability Wide variety of media options (copper, fiber, fiber ring, wireless) available Producer/Consumer services let you configure devices, control, and collect information over a single network Low integration and maintenance costs with one network from device to business system Provides the tools to use Ethernet technology in industrial control applications
