The Precision Agriculture (PA) cycle is composed of phases like mapping the spatial variability of the culture parameters, data analyses and treatment of the field. The multidisciplinary practices on this phases use embedded electronic and remote sensing in agricultural machinery. This practices demand researches of sensors and communication networks for data acquisition and control of Mobile Implement Control System (MICS) in the farm field to exchange with Farm Management Information System (FMIS). The MICS composed with CAN-Based Distributed Control System (DCS) according to ISO 11783 (or ISOBUS) standard. The ISO 1173 standard provides the interconnection of electronic devices embedded in agricultural machinery and implements through a control and serial data communication network. The IsoAgLib is an Object Oriented C++ library that has the communication services and needed management systems according with the ISO 11783 standard. This library allows building ISOBUS compatible equipment without the protocols implementation contained in this standard. This work presents the parameters of compatible ISOBUS application with IsoAgLib computational tool to support phases of PA cycle. This work also carries out the Information and Communication Technology (ICT) among MICS and FMIS, through eXtensible Markup Language (XML) format of data. The CAN-Based DCS (or MICS) consists in two parts, one on the tractor and other on the implement. The tractor composed of Universal Terminal (UT), Task Controller (TC) and Global Navigation Satellite Systems (GNSS) receiver. The implement composed of IsoAgLib installed on portable industrial Personal Computers (PC) integrated with agricultural sensors or actuators. The third part is Geographic Information System (GIS) software installed on FMIS. The evaluation of the connection was done by analyzing the CAN messages thorough ISO 11783-bus among PC, UT, TC and GNSS during the agricultural process. After agricultural process, the XML data was transfer to GIS software to data analyses. The ISO 11783 standard fully supports the PA phases. This work could be a reference to compatible ISOBUS applications providing expertise of ISO 11783 extensive standard, PA and ICT applications for researchers and professionals.
