ULAN COMMUNICATION PROTOCOL FOR LABORATORY INSTRUMENTS, HOME AUTOMATION AND FIELD APPLICATIONS

PÍŠA, P.; SMOLÍK, P.

Abstract

The uLan protocol is message oriented multi-master communication protocol for microcontrollers. It uses 9-bit character format for addressing and link control and RS-485 physical layer. The protocol is used in HPLC instruments and analyzers for instruments control and data acquisition . The protocol has potential to be used in the home automation applications and some other industrial field applications for its open nature design and proven implementation. The software support is provided for more RS-485 cards, converters for PC RS-232 ports and embedded microcontrollers. One of applications utilizing uLan communication is CHROMuLAN HPLC system software, which provides affordable solution for HPLC assays mathematical data processing and complex HPLC instruments sets control over uLan communication network. Other successful field example utilizing uLan communication is agriculture automatic feeding system.
