Copy DDE/OPC Link

  1. From the RSLinx Classic main menu, select
    Edit > Copy DDE/OPC Link
    .
  2. Open the
    Copy DDE/OPC Link
     dialog box to establish a connection to the RSLinx OPC Server.
  3. Browse for the address string for your request. If you have a symbol file associated with the topic, you can browse offline. You can also manually enter the address string in the
    Data Table Address
     field. You can narrow your search using the
    Filter
     and
    Datatype
     controls.
    TIP:
    The Data Table Address field displays your selection as
    [topic name].itemid.
  4. Use the
    Block Size
     and
    Columns per Row
     controls to customize this information. These options appear only in the DDE link that is pasted in the clipboard.
    TIP:
    RSLinx Classic supports EDS parameters for DeviceNet topics and tags for topics with an associated tag name file. To use the feature, in the Data Table Address box, enter the tag or EDS parameter. Spaces are not permitted in EDS parameters, so you must convert any spaces to underscores (_).
  5. Once all the data is entered, click
    OK
     to produce the following:
    • The OPC Item ID is copied to the clipboard as CF_TEXT format. You can paste this link into VB code or the OPC Test Client.
    • The DDE link including any Block Size and Columns per Row information is copied as a link format to the clipboard. You can paste this link into an Excel spreadsheet.
