What applications are best suited to fieldbus?
Both H1 and HSE were specifically designed for process control. Because H1 and HSE have complementary characteristics covering diverse networking needs, FOUNDATION technology is appropriate for many applications. These include: closed-loop continuous control, batch sequencing, remote-I/O, and legacy system integration. The Fieldbus Foundations Safety Instrumented Systems (SIS) specification includes has an additional safety layer based on IEC 61508 requirements making it suitable for use in plant safety systems.
