Software extension for advanced technology zone

Abstract

This article deals with the hardware and the software extension for metallic loops which consist of the extension of a combination of digital and analogue alarm detectors. The design is uniting the Advanced Technology Zone (ATZ) and the Two Wire Interface (TWI). The ATZ is used for the analogue connection and the TWI is used for the digital connection. The new design can improve the existing state, capability of the system and the maximal number of connected detectors to the system. The paper also consists of explained schematics and the software extension for designed hardware. Several measurements were done to confirm functional and reliable design. © 2018, Danube Adria Association for Automation and Manufacturing, DAAAM. All rights reserved.
