dc.description.abstractENGLISH ABSTRACT: The recent performance improvements of wireless communication systems are presenting possibilites for the use of wireless networks for industrial applications, which typically impose severe restrictions in terms of response time and flexibility. Traditionally most of the industrial protocols employ cable connections, which have limitations in terms of flexibility and development oportunities. The industrial protocol used for this project, is the Modbus protocol. This protocol is developed and implemented on a wireless environment by using data radio modems. The Modbus protocol is a master/slave protocol which provides an industry standard for industrial data transfer. A Modbus driver is designed for radio networks, so that it can function with different PLCs and SCADA packages, supporting Modbus protocol. This enables control and monitoring to be excercised over a long distance, and enables control equipment to be placed as required and not with particular wiring restrictions.en_ZA
dc.description.abstractAFRIKAANSE OPSOMMING: Die onlangse verbetering in radiokommunikasiestelsels bied moontlikhede vir die gebruik van radionetwerke vir industriële toepassings, wat gewoonlik streng beperkings plaas in terme van responstyd en buigbaarheid. Tradisioneel is meeste van die industriële protokolle kabelgebaseer, wat redelik onaanpasbaar is. Die Modbus protokol is as basis in hierdie projek gebruik. Dit is 'n meester/slaaf industriestandaard, wat hier aangepas is vir toepassings met radiomodems. Die Modbus drywer is ontwerp om funksioneel te wees met 'n verskeidenheid van PLC's en SCADA pakette, wat die Modbus protokolondersteun. Dit stel beheer- en meetaksies in staat oor lang afstande en laat relatief vrye plasing toe van toerusting sonder bedradingsbeperkings.af_ZA
