DeviceNet System Quick Reference
DeviceNet System Quick Reference Important User Information Solid state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for Application, Installation, and Maintenance of Solid State Controls (publication SGI-1.1 available from your local Rockwell Automation sales office or online at http://literature.rockwellautomation.com) describes some important differences between solid state equipment and hard-wired electromechanical devices.

DeviceNet System Quick Reference Select Use this table to select the appropriate media for your system. For other media choices, refer to Chapter 6 in the On-Machine Connectivity Catalog, publication M116-CA001. Description Cat. No.
DeviceNet System Quick Reference Install Locate and mount the modules. Follow these steps to crimp the connectors. For thin round media, refer to the DeviceNet Media Design Installation Guide, publication DNET-UM072. Important: • • • Do not crimp the edge of the connector cover. Do not crimp at the back of the crimp block. Be sure to set the connector in the correct orientation. 1. Set the center of the connector cover (see arrows) in the center of the crimp block of the crimp tool. 2.
DeviceNet System Quick Reference Configure 193-DNCT Handheld Configuration Device, Revision 2.1 or Later The 193-DNCT DeviceNet configuration terminal is a handheld device that can configure, program, retrieve historical data, and monitor DeviceNet components, while directly connected to the network. Commissioning is made simple with the capability to upload, store, and download complete device configurations, while online with the network.
DeviceNet System Quick Reference Starting the 193-DNCT Terminal Attach and connect the 193-DNCT terminal to the DeviceNet network. This display appears for 10 seconds.
DeviceNet System Quick Reference Follow these steps to set the communication rate to 125 Kbps. 1. Press SEL to advance to BaudRate. 2. Select BaudRate and press the Up Arrow 3. Press ESC to choose 125 Kbps. to exit Setup. Change Node Number 63 to Node Number 1 No entry exists for node 1 in the Network Who dialog box because the device is currently at node 63. Follow these steps to change to node number from 63 to 1. 1. On the 193-DNCT keypad, press the Down Arrow Product Name’. 2.
DeviceNet System Quick Reference Create the 1756-DNB and 1769-SDN Scanlist by Using AutoScan The DeviceNet network AutoScan feature allows a scanner to automatically map a network of slave devices into its scanlist without the use of RSNetWorx for DeviceNet software. This greatly improves the ease of setting up a DeviceNet network, especially networks comprised of simple devices. When you enable AutoScan, the 1756-DNB or 1769-SDN scanner module searches for devices on the network that are not yet mapped.
DeviceNet System Quick Reference 6. If AutoScan is selected and set to Disable, press the Up Arrow 7. Press SEL to select Mapping and press 3, 2, and then Enter 8. Press SEL and then Enter to change to Enable. . to save your changes. AutoScan begins and the Active Nodes value increments. When the value reaches a node count of 6, AutoScan is finished and found all 6 nodes on the network. 9. Select AutoScan and press the Up Arrow 10. Press SEL twice and then press Enter to change to Disable.
DeviceNet System Quick Reference 5. Press the Down Arrow to navigate to and select 5 – E1 Plus and press Enter . A dialog box appears with the mapping details of the E1 Plus devices scanlist entry. You can temporarily disable the 1756-DNB scanner scanlist entry. 6. Press SEL to select Mapping. This entry lets you modify the size of the native data location for the controller you are using.
DeviceNet System Quick Reference Example: Configure the E1 Overload With your fully wired and operational network, there is usually some configuration required for one or more of the devices, including how the device will behave on the DeviceNet network or how the device will act as its main function. The 193-DNCT terminal can configure and monitor parameters in the devices connected to the network.
DeviceNet System Quick Reference Maintain Diagnostics and Troubleshooting The 193-DNCT terminal has some diagnostics built in that can be used to troubleshoot a DeviceNet network. These diagnostics include bus voltages, bandwidth utilization percentage, and CAN error counts. 1. Press the Down Arrow 2. Press Enter to navigate to Node 62 This DeviceNet HIM. to select the HIM. 3. Press the Down Arrow to navigate to and select the Network group and press Enter .
