Unlocking Modbus - The Hidden Language of Smarter Fans


Listen Later

How do hundreds of fans in a building "talk" to each other and to us? In this episode of AIRSTREAM Insights, we unravel Modbus, the communication protocol that has quietly powered industrial automation since 1979. Discover why ZIEHL-ABEGG relies on Modbus RTU for building ventilation, how it enables precise speed control, remote monitoring, and fault diagnosis, and why it still outperforms newer protocols in many industrial contexts.

We’ll also dive into the hidden security risks and what it takes to keep connected systems safe.
