OSMOX's goal is to provide standards-based connectivity to Modbus devices in open-source SCADA and HMI applications, specially over the Internet. Our technology of choice is XML, due to its well-known platform-independency and its capability to pass through network firewalls.
OSMOX architecture is derived from the "mono-Modbus" project, which
can be found here:
R&D Paper with Architecture and Downloads
MODBUS is a master/slave communication protocol present in many digital instruments as process controllers, programmable logic controllers, signal transmitters and dataloggers. It was originally written for the Modicon Controllers. MODBUS is a very popular protocol nowadays, so OSMOX should find immediate application in Industries and Laboratories. The specification for the MODBUS protocol is freely available at www.modbus.org.
OSMOX is being developed to fit the architecture described below:
OSMOX began in Universidade Federal
de Santa Catarina as a final project for the course in Automatics & Control
Engineering, and was supported by Fundação
CERTI's CMIP (Center for Metrology and Inovation in Processes).
The project was recently re-designed, expanding on its
original concepts. The "old" OSMOX (Open-Source Modbus OPC XML-DA) can
be found, as a historical record, in the following site:
