Abstract: A virtual fieldbus device module is a software or firmware module that enables an otherwise ordinary fieldbus device to become a complex fieldbus device, capable of registering and maintaining multiple fieldbus network addresses for one or more “virtual” fieldbus devices. Each virtual fieldbus device has one or more sensor inputs and appears to the fieldbus network as an individual physical fieldbus device, despite the complex fieldbus device only having one physical connection to the fieldbus network. The virtual fieldbus device module may be incorporated into a device's firmware or may be included in a memory plug-in capable of being removed. The communication packet processing of a complex fieldbus device running the virtual fieldbus device module includes receiving a communication packet over the fieldbus network, determining whether the address associated with the packet matches any of the addresses registered by the complex fieldbus device, and processing any packets that match.

Abstract: A controller for an automated apparatus includes a plurality of operating units which operate independently while cooperating with one another, each operating unit driving a plurality of input/output elements. The controller includes a program control device for programmatically controlling the plurality of operating units, a direct designating device which, when the program control device controls the plurality of operating units independent from an external unit, is for directly designating individual input/output elements by an exclusive first set of numbers within the automated apparatus, an external interface device for interfacing an external unit, and an indirect designating device which, when the program control device communicates with the external unit via the interface device, is for indirectly designating individual input/output elements by a mutually exclusive second set of numbers within each of the operating units. The indirect designating device has a converting device for converting the second set of numbers into the first set of numbers.
