Abstract

The use of the wireless application protocol architecture to provide a wireless channel to access the database operating under the commonly used distributed network protocol system running for SCADA in the power process plant is discussed. Distributed Network Protocol (DNP) is developed to be applied in the SCADA systems while the terminals and RTUs are presently connected through local area network. The conditions in a process plant are harsh and the site is remote. Resources for data communication are difficult to obtain under the environment and a wireless channel communication through a cellular phone is practical and efficient. The WAP API on power industry applications is one of the area for extensive attention. The WAP architecture provides an open application programming environment for defining the WAP server and WAP application interface modules. It is used to investigate the different WAP protocols and the Wireless Application Environment on the Internet and mobile service for accessing a computing system. The Nokia WAP toolkit is used as the tool for investigation. Eventually, the mobile service can be incorporated into the DNP protocol such that a wireless WAP phone can reach and operate the resources available in a SCADA system.
