The Internet has grown greatly over the last 15 years. Leveraging the availability of the Internet and wireless technology, SCADA vendors initiate remote access solutions, which allow virtually every telemetry and monitoring device to be associated to the Internet and thereby to your terminal of choice. It allows you to be connected to your network or device, without being confined to the office.An architecture and proposal of a solution for virtual instrumentation in SCADA systems. The aim of this method is to propose a technique to design virtual instrumentation based on software constituents, which ensures uniform, reliable and extensible access to the tasks of the SCADA hardware components. Security is controlled by embedding IP tools into semantic protocols. Keeping path of all the authorized IPs and the network connections among them is a first requirement. HMI Management HMIs are gatherings of virtual instruments, together with the collaboration instruct among them. This is the reason why handling HMIs boils down to managing virtual instruments. So, the semantic protocol must insert content and interface templates, such that an HMI examined by the HMI management system can respond with its own content and interface structure.
