RS485, Modbus and BACnet: Basics & Practical Applications
Alongside KNX, RS485, Modbus and BACnet are among the most important communication standards in modern building automation. But which system is the right choice for which application? In this webinar, our speakers will introduce the fundamentals of these three technologies, explain their key differences and demonstrate typical applications in commercial buildings using practical examples.
In addition to the communication standards themselves, the webinar will focus on the latest solutions from Elsner Elektronik. You will get to know the new Suntracer pro BACnet weather station – the world's first native BACnet MS/TP weather station – as well as Windancer Modbus. You will also gain practical insights into commissioning, parameterisation and diagnostics. Furthermore, you will learn how weather stations and other devices can be efficiently integrated into Modbus and BACnet systems.
In this webinar, you will learn:
-
the differences between RS485, Modbus and BACnet and when each system should be used,
-
which weather stations and devices are available for Modbus and BACnet applications,
-
the key features of Suntracer pro BACnet and Windancer Modbus,
-
what to consider during installation, commissioning and parameterisation,
-
how to analyse data and quickly identify and resolve common faults.
At the end of the webinar, our speakers will be happy to answer your questions.
‼️For the first time, all participants will also receive a 5% discount voucher for the Elsner Online Shop.*
