SAE - Automation, s.r.o. ~ View topic - 3rd int. workshop NeCST, SNMP OPC Server and OpcDbGateway

The 3rd International workshop NeCST co-sponsored by IFAC Technical Committee on Networked Systems (TC 1.5), European Commission and others took place on 20th - 21st of June 2007 in Nancy. Our products SAEAUT SNMP OPC Server and OpcDbGateway were mentioned in three presentations on this workshop.

Prof. R. J. Patton from the Univerrsity of Hull, U.K. in the presentation to the theme „Integration of OPC Tools in Networked Control Systems“ presented usage of OPC tools for FDI/FTC in NCS and described using of our OpcDbGateway as communication intermediate in hierarchical structure with global controller and local controllers. Control algorithms in this illustrative example of Autonomous Control over the Network were implemented using MATLAB and OPC client within the OPC toolbox. Throughout the described experiment the four computers were permanently connected to the internet. The efficiency and minimalist approach provided by the OpcDbGateway in the transmission of information has enabled this network to function without expected communication problems: e.g. bandwidth limitations, packet collisions and other causes of time-delays or loss of information.
