GWY-01-DNT-01 MANUAL – REV. 02 CHAPTER 5: DEVICENET INTERFACE CHAPTER 5: DEVICENET INTERFACE 5.1 DEVICENET OVERVIEW DeviceNet is a digital, multi-drop network based on the CAN (Controller Area Network) specification, which permits easy connectivity between industrial controllers and I/O devices.
GWY-01-DNT-01 MANUAL – REV. 02 5.2.2 CHAPTER 5: DEVICENET INTERFACE Configuring Gateway and PLC DeviceNet Communications After importing the .EDS file and rebooting the host computer (or after restarting your Rockwell Automation software), follow the steps below to continue configuring DeviceNet network communications between the Gateway and a ControlLogix PLC. 1 On the host computer, start RSNetWorx for DeviceNet. 2 Go online (click NETWORK and select ONLINE).
GWY-01-DNT-01 MANUAL – REV. 02 CHAPTER 5: DEVICENET INTERFACE The Scanner Configuration Applet in RSNetWorx will begin scanning the specified network. This procedure may take some time depending on the speed of the bus and the number of devices connected. Node addresses are scanned from zero to 63. The default node address for the Gateway is 63.
GWY-01-DNT-01 MANUAL – REV. 02 4 CHAPTER 5: DEVICENET INTERFACE When the scan operation has completed, click “UPLOAD”, in the Scanner Configuration Applet dialog box, to update the configuration of the RSNetWorx software. Figure 5-3: Updating Configuration in RSNetWorx NOTE: The 1756-DNB/A is a Series A DeviceNet Bridge / Scanner Module.
GWY-01-DNT-01 MANUAL – REV. 02 CHAPTER 5: DEVICENET INTERFACE The Gateway will be added to the list of DeviceNet hardware in RSNetWorx. 6 Next, select the Gateway from the list of DeviceNet hardware and edit its I/O Parameters. Set the Input Size and Output Size parameters according to your application requirements, then click “OK.” In the example below, 30 input bytes and 30 output bytes will be scanned per polling cycle. 7 NOTE: Strobed mode is not supported by the GWY-01-DNT-01.
GWY-01-DNT-01 MANUAL – REV. 02 CHAPTER 5: DEVICENET INTERFACE The following images display the Input and Output properties tabs (in RSNetWorx for DeviceNet) for the 1756-DNB/A DeviceNet Bridge / Scanner Module after running the Scanner Configuration Applet for a second time. The scanner module, in this case, only identified one node, the Gateway, at node address 63. The tabs are used to identify where input and output data is mapped for each identified node.
GWY-01-DNT-01 MANUAL – REV. 02 9 CHAPTER 5: DEVICENET INTERFACE Next, verify the mapping of the address where the PLC will retrieve output data from the Gateway. In the image below, output data is mapped to start at 1:O.Data(0).0 on the PLC. Figure 5-6: 1756-DNB/A Output Properties Tab 10 Lastly, click “Apply” and select “YES” to download the configuration and mapping settings from RSNetWorx to the PLC.
GWY-01-DNT-01 MANUAL – REV. 02 5.2.3 CHAPTER 5: DEVICENET INTERFACE C o n f i g u r i n g D a ta R a t e a n d N o d e A d d r e s s As noted, each device, computer and controller on a DeviceNet network is considered an individual node for which a unique Node Address number (between 0 and 63) is assigned. The node address provides a means of numerically identifying each device on a DeviceNet network.
GWY-01-DNT-01 MANUAL – REV. 02 CHAPTER 5: DEVICENET INTERFACE The image below displays an example of the data contained in the two I/O Controller Tags for the Gateway. Figure 5-7: Gateway I/O Controller Tags (in RSLogix 5000) 5.2.5 DeviceNet - Handshaking Example This example describes the sequence of events for a simple command and response. All data is written in 2-byte WORD format and stored in 2-byte “registers.” The Output Controller Tag holds command data written by the PLC.
GWY-01-DNT-01 MANUAL – REV. 02 CHAPTER 5: DEVICENET INTERFACE 3. Following execution of the command, the Gateway writes its response to the Input Controller Tag, starting with the 2-byte Produce Data Size, at Local:2:I.Data [2] and the actual data beginning at Local:2:I.Data [3]. It then increments the counter value at Local:2:I.Data [1]. This alerts the PLC to the new data available (the Gateway generated response, in this case). 4.
