Abstract
The invention provides, in some aspects, improved apparatus for configuring a control system. The apparatus includes a model made up of objects representing devices of such a system, including, at least one device that defines and/or controls communications on at least a portion of a network within that system. That device is referred to, here, as a “bus master” and the portion of the network is referred to as a “segment.” The object (or objects) representing the bus master can include information defining timings, port assignments and/or other aspects of the configuration of the segment. A download service transfers configuration information from objects in the model to devices in the control system. This includes transferring to the bus master communications configuration information for the segment. A download service according to this aspect of the invention generates—e.g., for logging by a change tracking system—indicia of the configuration information transferred to the bus master. The download service can likewise generate for logging (by the change tracking system) information transferred from the model to other devices in control system.
