Here’s a straightforward, technical comparison of BACnet, Modbus, LonWorks, and KNX, focusing on architecture, data modeling, networking, and real-world usage. 1. High-Level Summary Feature BACnet Modbus...
BACnet (Building Automation and Control Network) is an open communication protocol used in building automation systems. It allows equipment from different manufacturers—like HVAC systems, lighting controls,...
The 4-20 mA current loop has been the standard for signal transmission and electronic control in control systems since the 1950’s. The 4 mA to 20 mA current loop is a common method of transmitting...
All iSMA Universal Inputs cannot read a 4-20mA signal directly, so to read a 4-20mA sensor you will find in the box of every iSMA device (with Universal Inputs) a set of 200 Ohm resistors. It is extremely...
