Abstract:
A setup information controlling device connectable to an instrument, which is subject to control, and an instrument monitoring terminal that is provided with the instrument and stores setup information that includes a protocol for communicating with another instrument. The setup information controlling device includes an acquiring portion that acquires the setup information from the instrument monitoring terminal, a storing portion that stores the setup information that has been acquired by the acquiring portion, and a transmitting portion that transmits the setup information, corresponding to an address, to the instrument that is connected to that address, which corresponds to the setup information stored in the storing portion.

Abstract:
Control systems and methods for controlling certain systems, devices, and apparatus are described. A control system may include a memory and at least one processor. The memory may be operable to store both a Foundation Fieldbus protocol that facilitates communication with one or more Foundation Fieldbus devices and a second protocol that facilitates communication with one or more control devices. The at least one processor may be operable to access both the Foundation Fieldbus protocol and the second protocol, and to control the one or more Foundation Fieldbus devices and the one or more control devices. A network may facilitate communications between the at least one processor and both the one or more Foundation Fieldbus devices using the Foundation Fieldbus protocol and the one or more control devices using the second protocol.
Abstract:
In a method for monitoring a network of process automation technology, wherein the network includes a number of field devices, which are connected via a fieldbus with a superordinated unit, there is created for a network application, which analyzes the network, a network description, which corresponds to a device description for field devices. Therewith, the network application can be integrated in a simple manner into a plant monitoring application and status information of the network can be output via the plant monitoring application.
Abstract:
Systems (200, 230, 240) and methods (700) for controlling a simulation of an operation of a Fieldbus system (100) comprising at least one FIM (114, 116) communicatively coupled to field devices (122, 124). The methods involve initiating a current simulation (CS) of an operation of the FIM and/or field devices. The methods also involve obtaining intermediate simulation information (ISI) indicating a status/progress of CS. The methods further involve displaying ISI to a user of a simulation system and displaying visual elements (610, . . . , 620) for controlling the progress of CS to the user. Gantt charts (672, 674) for the FIM/field devices and visual content showing data exchanges between software elements and/or hardware elements of the simulation system can further be displayed to the user. The visual elements can facilitate speeding up CS, slowing down CS, moving the progress of CS backwards/forwards, and/or stopping/re-starting the CS.

Abstract:
An auto-tuner is adapted to be used in a distributed process control network having a communications network that communicatively couples a process controller, which executes a process control routine, and one or more process devices used in a process control loop. The auto-tuner includes a first tuning element configured to cause a control entity to force the process loop to undergo an auto-tuning procedure and a tuning data stack operating within one of the process devices to receive and store a tuning signal associated with the control entity along with a time stamp indicating the time the tuning signal was acted on by the device. A measurement data stack is disposed in the same or a different process device and operates to receive and store a response or measurement signal generated by the process device along with a time stamp indicating when the response signal was generated or detected. A second tuning element which may be, for example, in a controller or a workstation, periodically receives data from the tuning data stack and the measurement data stack and determines a tuning parameter to be used in tuning the process loop.
