Transport map for a PLEX transport

This Transport Map panel allows you to define the content of the PLEX based request to a Rockwell PLEX endpoint. With this panel you will be able to:

  • Query the data source call from the PLEX server
  • Specify input and output logical variables and how they map to the PLEX message
  • Specify (maximum) number of rows returned by a result set output
  • Flag output parameters as inputs if they are not indicated as such from the data source query

Defining a PLEX transport map

  1. Using the Workbench, access the node and navigate to the Transport Map definition panel. Click New to display a Transport Map definition panel.
  2. Click the Transport Type drop-down and select PLEX.
  3. Click the Transport Name drop-down and select an existing PLEX transport.
  4. Enter the numeric key of the Plex DataSource and then select the Query button. This will retrieve the input and output properties by querying the server endpoint defined in the transport.
  5. Plex Transport Map
  6. Select the Validate button if you want to validate the input/output structure of the PLEX message that would be generated by this transport map.
    A request is not made to the server when you select the Validate button.
    For example:
    Plex Map Preview
  7. Select the Save button to save the definition to the node.

Setting additional input parameters

The PLEX transport map definition relies on queries from the server to determine what fields are input or output fields.

In some cases, a field flagged as output may also be optionally an input field, but not indicated as such in the query result. In this instance you can select the output field, right click on it to get the context menu, and select "Add as Input".

Add as Input

If it doesn't already exist as an input, the field will be added to the top of the list as a string input field.
