The mapped connections are used to transfer complex data structures between the two systems. While datasets in DeltaV may be assigned as output with read-back, any individual register will be either input or output. This device requires two Class1 connections: one for IO data and one for status information. Open the VimNet Explorer.

The IP address can be set with the web page only if the linking device already has a valid IP address. Typically, you can do this by using the DIP switch to force the linking device to use a temporary IP address after you cycle power.
Follow these steps to configure the IP address with the web page. Browse to the linking device by entering the temporary IP address in your web browsers address bar and click Enter. In the left pane, click IP Configuration. You see the Enter Network Password dialog box. In the Username field, enter Administrator. Leave the password field blank. Click OK.
You see the IP Configuration dialog box. Enter the following values into the IP Configuration dialog box. Enter Any valid value. See your system administrator for a valid IP address. Click Submit Values. Follow the on-dialog box prompts. Click the Reset Module button to reset the linking device. Click Add New. In the Configure Driver window that appears, enter the IP address of the linking device.
Click Close. Click Next. Click Next or Finish for the remaining option dialog boxes. In the left pane, click the RSLinx Ethernet driver you added previously. In the left pane, click DeviceNet, DeviceNet. When asked to upload from the network, click OK to perform a single pass browse. You see the Node Commissioning dialog box. On the Node Commissioning dialog box, click Browse. You see the Device Selection dialog box.
You see the EN2DN linking device in the left pane. Click on the EN2DN linking device in the left pane. It appears in the right pane. If a warning text box asking you if you wish to continue appears, click Yes. Enter the desired MAC address or data rate, then click Apply.
If only the communication rate is changed you must cycle power to the linking device before the new communication rate will take effect. By default, the linking device has Autobaud enabled. If a warning text box appears, click Yes.
You see the Class Instance Editor dialog box. Click Execute. You may also have to cycle power to the slave devices. If the linking device is the only master on the DeviceNet network, do not enable autobaud. Automatic communication detection requires traffic on the network. There is typically no traffic until the master establishes connections. The Input table size cannot be larger than bytes.
The Output table size cannot be larger than bytes. Either table may be empty 0 bytes. Refer to RSNetWorx online help for complete details. Wait for browsing to complete. Wait for the device information to be uploaded from the network.
Double-click the linking device icon to bring up the Module Description dialog box. Several tabs appear on the top of the dialog box. Click the Scanlist tab. In the informational text box that appears, click Upload. The dialog box shows two columns. On the left is a list of available devices that may be added to the scan list.
On the right is a list of devices that are configured in the scan list. Check AutoMap on Add. Select the Input tab.
The Input mapping dialog box is displayed. The top portion of this dialog box gives a list of the devices in the scan list from which the linking device receives input data. The bottom shows the location in the Input table where the data will be placed for each device. This shows the format of the Input table of the linking device. Select the Output tab. The Output mapping dialog box is displayed.
The top portion of this dialog box gives a list of the devices in the scan list to which the linking device will send output data. The bottom shows the location in the Output table where the data will be placed for each device. This shows the format of the Output table of the linking device.
Click Apply, and click Yes to download the scanlist to the linking device. TIP The linking device starts scanning as soon as it finds entries in its scanlist. However, in Idle mode, output data will not be sent to the devices. You see the New Controller dialog box. From the Type pull-down menu, choose the controller type. From the Revision pull-down menu, choose the controller version. Enter a name for the controller project. A project is created.
Click New Module. You see the Module Properties dialog box. In the Slot Number field, enter the slot number in which the device resides. Click Finish. On the Select Major Revision dialog box that appears, choose the major revision from the drop-down box. In the Name field, enter a module name. Click the IP Address radio button and enter the IP address for which the linking device is configured. If you see errors in this field when you are online, see the table following this illustration.
You can now use the linking device as both a bridge and a scanner. Write a user program to use the linking device on the network. To view information specific to the RSLogix tags that pertain to the linking device, do the following: a. In the right pane, you see the EN2DN linking device controller tags. Review data in the fields that appear for each tag, as described in the section entitled Assembly Objects and Connections on page The input and output assemblies are linked to the input and output tags created in RSLogix software.
The status assembly provides current status information about the linking device. The assembly instances associated with these three assemblies are listed in the following tables. Input Assembly The input assembly contains a bit status register followed by the data in the linking devices input data table. Data[0 ] The input data format and content is determined by the DeviceNet scanner configuration.
The data appears in the table as it is mapped from the DeviceNet input connections. The input data in the assembly is DINTs long; however, only the size of the input data table will be used. The remaining space will be filled with the value 0 zero. Data[0 23] The output data format and content is determined by the DeviceNet scanner configuration.
The data appears in the table as it is mapped to the DeviceNet output connections. The output data in the assembly is DINT long; however, only the size of the output data table will be used. The remaining space will be ignored. Status Assembly The status assembly is a collection of status and diagnostic information for the linking devices DeviceNet network interface.
