WebHART ("Highway Addressable Remote Transducer") is a communication protocol designed for industrial process measurement and control applications. It's called a hybrid protocol because it combines analog and digital communication. WebUART frame format UART frames contain start and stop bits, data bits, and an optional parity bit, which will be explained below. As with most digital systems, a “high” voltage level is used to indicate a logical “1” and a “low” voltage level is used to indicate a logical “0”. small homes tucson az
