A previous change to the 0x0083 command (Set Handling Operation) included new fields, and assumed all blackbox software could handle them. That was not the case, only the 5226 is capable of using the updated command. Pathfinder was updated to check the Blackbox model and build, and only send these values if the Blackbox is known to be able to handle them.

The FOLDBUS spec provides for a variety of exception responses to be returned by controllers in the event of certain errors. While Pathfinder has long captures this information, it did little more than log it.

Now the fact that the controller returned an exception code is indicated on the Connection Status Summary icon (bottom left, near the shutdown button) and details of the exception code are provided in the Connection Status Details view (accessed by clicking on said icon).
