Abstract

This work presents the relevant information for development of OPC data servers in the two more promising ways of this standard: OPC DA and Web Services. A proposal of necessary steps for the development of this type of system is presented, in the context of a real situation of data acquisition using cellular telephony technology as access way. The results of conformity and performance tests are presented and demonstrate the interoperability capacity supplied by the implemented solutions.
