How to Configure Data Sharing Using an Existing Variable and the Mapping Dialog

The following process is used to configure Data Sharing between a BACnet object and a variable that already exists in the Variables Tree. The same process is used for both Online and Offline modes.

  1. Open the Application Explorer and expand the configuration tree to display a previously configured BACnet network.
  2. From the task pane, select the Mapping task. The Mapping dialog opens.
  3. Select an object type (left pane) and an instance (upper right pane).
  4. Right click on the selected object in the upper right pane and, from the context menu, select Map an existing variable. The Variable Selector dialog opens.
  5. Select the variable to be mapped. Click the Apply button and the link between the object and the variable is made. ClosedShow picture
  6. Repeat steps 4 and 5 for each of the variables to be mapped.

The same procedure is used to map a variable to a specific property, or an event/alarm, except that you use the lower right pane.

How to unmap a variable

  1. Open the mapping dialog and select the variable to be un-mapped.
  2. Right-click on the selected variable and, from the context menu, select the command Unmap variable.
  3. A dialog will appear asking for confirmation. Click OK to confirm the operation.
