FOUNDATION Fieldbus: what it actually is, how it works in the real world, and the practical stuff nobody tells you until you’ve already made the mistake.
In this episode, I cover how one shielded twisted-pair cable carries both power and data to your field instruments, the difference between the H1 field layer and the HSE backbone, how devices can run PID loops without a central controller using Control in the Field, the termination mistake I see more than any other, and a handful of practical tips I’ve picked up over 36 years in water, wastewater, and industrial automation.
Whether you’re new to digital field protocols or you’ve been wiring 4-20mA loops for years, this one breaks it down from the ground up, no textbook language, just real-world experience from the trenches.
