“…The simulator was developed in LabVIEW using the G graphical programming language, "native" language in this environment. Each FBSIMU module or software unit simulates an element or a structure of a real FOUNDATION Fieldbus system (Mossin et al, 2008).…”

“…The FF standardized a set of 10 basic FBs (Fieldbus Foundation, 1999a), a complementary set of 11 advanced control blocks (Fieldbus Foundation, 1999b) and a special flexible FB intended to be fully configurable, ie, internal logic and parameter, by users (Fieldbus Foundation, 1999c). The standard and advanced block sets provide mathematical and engineering calculations necessary to configure typical industrial control loop strategies (Mossin and Pantoni, 2009). All operations including data acquisition and optimization by PID were executed entirely in the field intelligent instruments of the fieldbus system by means of FBs.…”

This paper presented a comprehensive design and implementation of control and optimization for the combustion system in heat-supplying boilers based on a fieldbus, mainly including the air-to-fuel ratio optimization algorithm based on a PID controller and soft measurement methodology for airflow based on the orifice nature of the air pre-heater. After process description and general control schemes were presented, measurement and control principles for the system were given. After an optimization algorithm for air-to-fuel ratio with constant step was introduced briefly, an adaptive optimization algorithm based on a PID controller was proposed, and then detailed design was presented. Advantages of the proposed adaptive optimization algorithm can be seen after comparison with a former algorithm. Approaches for the soft measurement of airflow in a boiler system based on differential air pressure between the inlet and outlet of the air pre-heater and that of fuel were presented. The complete control strategies for the designed system were given. Implementation of the whole system by a Foundation Fieldbus, including structure design for the control system and soft configurations design for the proposed optimization algorithm, were presented at length. Control effects of the designed system were given, demonstrating tat the design of the whole system was a success by running it reliably for a long time. Some important conclusions on the proposed methodologies and designs in measurement and control using the fieldbus in combustion control were presented at the end of the paper.

“…Although standardized technology, FF is based on relatively complex concepts such as instrumentation, data communications, computerized automation controllers, and engineering software, thus it has a slow learning curve [13]. In shortening the time for the implementation phase of project work, a useful suggestion on using FF function blocks to enable failure-safe mechanism for safe loop action of the PID control is reported [14].…”

Detailed knowledge of how to balance between safety and availability for instruments is essential to successful design and implementation in fieldbus-based process control systems. The configuration correctness is crucial to actually obtain the benefits of digital fieldbus technology used. In actuality, a number of device parameters must be set to provide the required functionalities. This paper focuses on improving safety and availability for the proportional-integral-derivative (PID) and cascade control strategies using Foundation Fieldbus (FF) with control in the field. The aim of this paper is to analyze the logical behaviors of PID and cascade loops in two conflicting purposes for studying how different configuration options affect the interlocks between function blocks located in instruments as well as the initialization and fail-safe mechanisms in response to invalid measurements. For safety purpose, the interested control loops are configured to bring the process to a safe state in the presence of a fault. For availability purpose, the interested control loops are configured to keep the process running in the event of a failure. A water tank process is utilized as a case study for control loop implementations. Interactions between the status propagation and mode shedding for demonstrating the studied control loop behaviors are examined experimentally in Petri net models. In addition, the function block options for bumpless transfer and setpoint tracking are also described. The proved configuration method for proper operations in balancing the interests of safety and availability is proposed.
