Conclusion

As the world converges, diverse systems are also beginning to converge. In the past, it would seem absurd to mix the telephone and a computer networks, but now it is an idea that is making high ground in the telecommunications sector. Extensibility, therefore, is also an important feature as it provides the flexibility to extend and retool the system for different transmission and interfacing media. With the availability of the Internet, mobile networks and others, there exists new means of providing greater access to SCADA systems. The SCADA-TEMS SACP is able to provide a simple interface for allowing the different networks to communicate to the SCADA-TEMS. The mobile GSM network and Internet are only examples of the many networks that can be linked to the SCADA-TEMS via SACP. At the end of the day, new ways of doing old things are emerging. The SCADA-TEMS is only one of them. SCADA systems have been the target of various studies especially in the field of power distribution. Distributed control is the essence of any SCADA system. For it provides a cost effect way of monitoring and control multiple remote sites. The SCADA-TEMS provides distributed control, extensibility and virtual coverage.
