A-2 Publication DNET-UM004A-EN-P - March 2004 Table of Contents 8 Publication DNET-UM004A-EN-P - March 2004 Chapter 1 Before You Begin What This Manual Covers This manual guides the development of a control system that uses a Logix5000TM controller and a DeviceNetTM network. This manual shows how to: · · · · · connect the controller to the network establish control of the devices interlock and share input data access the network via an operator or HMI terminal interpret status and diagnostic information To control the devices on a DeviceNet network, a Logix5000 controller uses one of the following scanners: CompactLogixTM Scanner 1769-SDN ControlLogix® Scanner 1756-DNB ControlNet to DeviceNet Linking Device 1788-CN2DN DriveLogixTM and FlexLogixTM Communication Card 1788-DNBO EtherNet/IP to DeviceNet Linking Device 1788-EN2DN SoftLogixTM 5800 Scanner 1784-PCIDS S Allen-Bradley 1784-PCIDS Scanner I/O N MOD NET 31288-M 1 Publication DNET-UM004A-EN-P - March 2004 1-2 Before You Begin This manual also provides a basic level of information to use the following devices on your DeviceNet network. POINTTM I/O Interface 1734-PDN POINTTM I/O Adapter 1734-ADN and 1734-ADNX POINTTMBlock I/O Module 1734D FLEXTM I/O Adapter 1794-ADN Adapter Status DeviceNet Status PointBus Status 1734-ADN System Power DeviceNet Power Publication DNET-UM004A-EN-P - March 2004 Before You Begin 1-3 Preliminary Actions Before you configure and program your DeviceNet network, complete the following actions: 1. Choose whether to use a single network or several distributed networks. (For more information, see page 1-5.) single network controller scanner device device device device device several smaller distributed networks (subnets) linking device linking device controller device device device device device device 2. Choose a scanner. (For more information, see page 1-5.) If you are using: single network subnets EtherNet/IP ControlNetTM And the main network is: Use this scanner: Corresponding scanner for your controller EtherNet/IP to DeviceNet Linking Device 1788-EN2DN ControlNet to DeviceNet Linking Device 1788-CN2DN 3 Choose how to connect your computer to the DeviceNet network. (For more information, see page 1-6.) . Connect to another network and bridge to the DeviceNet network. Requires a bridge device. Connect directly to the DeviceNet network. Requires a DeviceNet interface device. 4. Choose a baud rate. (For more information, see page 1-9.) 125K bit/s (default-- good starting point) 250K bit/s 500K bit/s bridge device device device device device Publication DNET-UM004A-EN-P - March 2004 1-4 Before You Begin 5. Calculate how much scanner memory you need. (For more information, see page 1-11.) A. List the devices on your network. B. Record how many bytes each device sends to your control system (input data) and gets from your control system (output data). Device Address Input Size of Device (bytes) 1 9 Input Memory in Scanner (DINTs) 1 2 3 2 8 Output Size of Device (bytes) 1 5 Output Memory in Scanner (DINTs) 1 2 2 2 7 start/stop buttons I/O adapter w/ modules Total E. Total memory that you need in the scanner. C. Convert the input and outputs sizes to DINTs, where: DINTs = (bytes/4) rounded up to an integer. D. Add several DINTs between each device in case you want to make changes later. 6. Assign an address to each device. The following addresses are recommended but not required. (For more information, see page 1-13.) Tip: For flexibility as you develop your system, leave gaps between addresses. Gaps have no effect on system performance. Give this address: 0 1 to 61 62 63 To this device: Scanner Your devices Give the lower addresses to devices with 15 bytes or more of input or output data. Computer interface, such as a 1770-KFD or 1784-PCD device Leave open for new or replacement devices. 7. Make sure you have the required software. To configure the network: If: every device on your network (except the scanner) uses 4 or less bytes of input and output data some devices use more than 4 bytes of input or output data To program the controller, use RSLogixTM 5000 software. To connect your computer to the network, use RSLinx® software. And your scanner is: · ControlLogix® 1756-DNB · FlexLogixTM 1788-DNBO any Configure the network with: RSLogixTM 5000 software (For more information, see chapter 4.) RSNetWorxTM for DeviceNet software (For more information, see chapters 2 and 6.)

DINT The scanner collects output data from the controller... To organize your devices into a DeviceNet network, either: Place all your devices on a single network and connect the controller directly to the network via the scanner. controller scanner device device device device device main network Break up your devices into several smaller distributed networks (subnets). Place a scanner (linking device) on each network. Connect the scanners to the controller via an EtherNet/IP or ControlNet network (backbone). controller linking device subnets device device linking device device device device device This option: single network Has these advantages: · lower cost · 1 network to manage · scanner is local to the controller And these disadvantages: · shorter distances · more devices on the network = slower performance on that network · more power supply requirements · higher cost · multiple networks to manage · scanner is remote from the controller subnets · shorter runs on subnets, more total distance · fewer devices on the subnet = faster performance on the subnet · simpler power supply requirements Publication DNET-UM004A-EN-P - March 2004 1-6 Before You Begin To choose a scanner, use the following table: If you are using: single network And: CompactLogixTM controller ControlLogix® controller DriveLogixTM controller FlexLogixTM controller SoftLogixTM 5800 controller subnets EtherNet/IP main network ControlNet main network SoftLogix5800 1784-PCIDS EtherNet/IP to DeviceNet Linking Device 1788-EN2DN ControlNet to DeviceNet Linking Device 1788-CN2DN Use this scanner: CompactLogix 1769-SDN ControlLogix 1756-DNB DriveLogix and FlexLogix 1788-DNBO Bridging Across Networks Logix5000TM devices can usually communicate with devices on other networks with no additional configuration or programming. · A bridge connects two different networks. The bridge is either: ­ single device with communication ports for two different networks ­ separate communication devices in the same chassis · For example, the bridge device shown below is connected to both EtherNet/IP and DeviceNet networks. Device 1 on EtherNet/IP can communicate with Device 2 on DeviceNet through the bridge. EtherNet/IP network switch Device 1 bridge DeviceNet network Device 2 Publication DNET-UM004A-EN-P - March 2004 Before You Begin 1-7 Communication can bridge these networks:. A device on this network Can access a device on this network: EtherNet/IP EtherNet/IP ControlNet DeviceNet RS-232 (1) ControlNet: yes yes no yes(1) DeviceNet: yes yes yes yes RS-232(2): yes yes no yes yes yes no yes To use RSNetWorx software to configure and schedule a ControlNet network, we recommend that you either: · connect to an EtherNet/IP network and bridge to the ControlNet network · use a 1784-PCC interface device to connect directly to the ControlNet network Typically, this is a point-to-point connection between a Logix5000 controller and another device, such as a PanelViewTM Plus operator terminal. (2) In this example, a workstation configures a drive on a DeviceNet network. The workstation bridges EtherNet/IP to reach the drive.
