Techniques for flexibly configuring an operating process plant or process control system enable a change to a parent object to be selectively propagated to child objects derived from the parent object, so that a first subset of child objects and their respective instantiations are updated with the change, while a second subset and their respective instantiations remain unchanged. The parent object may be a class or instance process object corresponding to a process entity, and the first and/or the second subset of child objects may be selected. In some cases, the change may have been a propagated change, to the parent object, from a child object that is excluded from the first or the second subset of child objects. In some cases, the change may first be propagated to an instance object derived from the parent object, and then propagated from the instance object to a child object. |
