Steel plants are facing challenges in efficient energy monitoring for cost reduction. The present days solution employs SCADA systems which heavily depends on different independent heterogeneous automation systems. The typical interfacing issues includes MS COM/DCOM based OPC technology at application level. The energy parameters which requires to be displayed on real time basis puts another challenges for data communication. The traditional approach for data communication requires physical interconnection of heterogeneous automation systems by adding redundant hardware like firewalls, routers, gateways PCs. This in turn also leads to increased vulnerability towards it security of critical plant process.
A proposal other than MS COM/DCOM which will not rely on complex OS level setting, can ease out interfacing issues. An alternative mechanism for data communication on real time basis is required.
