“…In fact, FF is completely digital end-to-end, from the sensor to the actuator, and it has several benefits over loops using hardwired 4-20 mA wiring and on/off signals [28,29]. The wiring connections of the 4-20 mA HART ® communication protocol are illustrated in Figure 2a, while Figure 2b shows the connections for Foundation Fieldbus [30,31].…”

A safety instrumented system (SIS) is a complex unit composed of a set of hardware and software controls which are expressly used in critical process systems. A SIS should be specifically designed to obtain the failsafe state of the monitored plant or maintain safety of the procedure or a process when unacceptable or dangerous conditions occur. This paper focuses on condition monitoring and different diagnostic solutions used in safety instrumented systems, such as limit alarm trips, on-board diagnostics, and logic solver diagnostics. A case study consisting of the design of a safety loop using standard IEC 61508 for a complex safety instrumented system in the oil and gas field is presented in the paper using a diagnostics-oriented approach. The presented methodology aims at reaching the optimal tradeoff between IEC 61508 and the market requirements focusing on the best technological solutions to optimize diagnostics and safety and minimize the system’s response time in case of failure. The results of the application emphasize the importance of an accurate diagnostic strategy on safety instrumented systems for oil and gas plants.

“…It is widely adopted by numerous commercial field devices and many off-the-shelf interfacing board and component alternatives are available to the designers of instrumentation systems. As a result of this wide adoption, significant research effort has also been devoted to its realtime applications, characterizing and improving predictability of communications [24], [25] and the impact of delays on closed-loop control [26]. Unfortunately, size, power, and weight constraints associated with the design of autonomous mobile robots are much more severe and limiting than those associated with domains in which existing large-scale fieldbus alternatives are intended to be used.…”

The design and construction of complex and reconfigurable embedded systems such as small autonomous mobile robots is a challenging task that involves the selection, interfacing, and programming of a large number of sensors and actuators. Facilitating this tedious process requires modularity and extensibility both in hardware and software components. In this paper, we introduce the universal robot bus (URB), a real-time fieldbus architecture that facilitates rapid integration of heterogeneous sensor and actuator nodes to a central processing unit (CPU) while providing a software abstraction that eliminates complications arising from the lack of hardware homogeneity. Motivated by our primary application area of mobile robotics, URB is designed to be very lightweight and efficient, with real-time support for Recommended Standard (RS) 232 or universal serial bus connections to a central computer and inter-integrated circuit (I 2 C), controller area network, or RS485 bus connections to embedded nodes. It supports automatic synchronization of data acquisition across multiple nodes, provides high data bandwidth at low deterministic latencies, and includes flexible libraries for modular software development both for local nodes and the CPU. This paper describes the design of the URB architecture, provides a careful experimental characterization of its performance, and demonstrates its utility in the context of its deployment in a legged robot platform.
