events, including any errors, are shown in the status pane and recorded in a log file (Resync.log).
The resync log is stored in the drawing directory of the current OpenLNS CT network design.
17. If the OpenLNS CT drawing is being synchronized to match the network database and the
Automatically Drop Device, FB, and Subsystem Shapes check box was cleared, the Missing
Shape dialog opens for each object in the network database that is not represented in the
OpenLNS CT drawing.
a. Click OK. The Missing Shape dialog closes and you are returned to the OpenLNS CT
drawing.
b. Drag a single SmartShape from an OpenLNS CT stencil to the OpenLNS CT drawing to
represent the missing SmartShape. OpenLNS CT assigns the SmartShape to the specified
object in the OpenLNS network database.
c. Click Add-ins, point to Synchronization, and then click Resynchronize to re-open the
Missing Shape dialog and assign the next missing SmartShape.
d. Repeat steps a – c for each missing SmartShape. Once all missing SmartShapes have been
added and the connections have been updated, resynchronization will be complete.
Tips:
• The first time you resynchronize an OpenLNS CT drawing created with a previous version of
OpenLNS CT, most connections that span multiple documents will automatically be deleted and
then re-created. This speeds up any subsequent resynchronizations.
• The first time you resynchronize an OpenLNS CT drawing created with an older version of Visio,
select the Reset Visio Workspaces option in the Synchronize OpenLNS CT Drawing dialog.
This automatically saves the documents in your drawing to the Visio 2010 or Visio 2003 format.
Otherwise, OpenLNS CT prompts you whether to save the documents in your drawing in Visio
2002 format or the current Visio format. If you answer Visio 2002, OpenLNS CT will continue to
prompt you every time you resynchronize the drawing.
• If you have stencils from an older version of Visio that you want to use, open and save the stencils
individually in Visio 2010 or Visio 2003. Otherwise, Visio will prompt you each time the
drawing is closed as to whether to save the changes to the stencil, but it won’t save any changes
because it opens these stencils as read-only.
Refreshing the OpenLNS CT Network
OpenLNS CT caches data from the OpenLNS network database to improve performance. If another
OpenLNS application or plug-in updates data that has been cached by OpenLNS CT and does not
generate an appropriate OpenLNS event, the OpenLNS CT cache may lose synchronization with the
OpenLNS network database. You can force OpenLNS CT to process and release the cache by clicking
Add-ins, pointing to Synchronization, and then clicking Refresh.
Merging OpenLNS CT Networks
You can initially install a large L ON W ORKS network as a number of smaller independent networks—
each with their own network database—and then later merge the networks into one network.
Examples of installations that may use this technique include the following scenarios:
• Multiple systems. When multiple systems are being installed, the installers for each system want
to install and debug their installation without interference from other systems. When each system
has been correctly installed, they can be merged into a single network.
• Incomplete infrastructure. Portions of a building, such as the floors of a high-rise, may need to
be installed before connectivity exists for the entire site (before there is a backbone channel
connecting the floors together, for instance). You can install each floor of the network as part of a
single network using a portable network server under a sequential network installation scenario, in
