Methods of synchronizing controllers in a building management system

A method of sharing one or more control parameters between a plurality of controllers, each of the plurality of controllers configured to control operation of a building component based at least in part on the control parameters, each of the plurality of controllers including one or more function block, where at least some of the one or more function blocks reference one or more of the control parameters, the method comprising:

• designating a first controller of the plurality of controllers as a source controller;
• designating one or more other controllers of the plurality of controllers as target controllers;
• assigning a master synch property to at least one of the one or more control parameters;
• and
• for at least one function block within the source controller, synchronizing one or more control parameters referenced by the respective function block of the source controller and that have been assigned the master synch property with corresponding control parameters referenced by a corresponding function block of each target controller, while not syncing the control parameters that have not been assigned the master synch property.

A method of programming a plurality of controllers, each of the plurality of controllers configured to control operation of a building component, the method comprising:

• creating a control logic for a first controller of the plurality of controllers, the control logic including a plurality of function blocks that reference one or more control parameters;
• designating the first controller as a source controller;
• designating other controllers of the plurality of controllers as target controllers;
• performing a synchronization operation between the source controller and each of the target controllers, wherein:
• when one of the target controllers does not have its own control logic, the synchronization operation includes copying all of the control logic from the source controller to the particular target controller;
• when one of the target controllers already has its own control logic, the synchronization operation includes copying only function blocks from the control logic within the source controller that are not present within the control logic of the particular target controller.
