The SCADA application, which monitors and displays the data from all the field devices like inverters, meters etc., is installed in the Local SCADA PC (on-site). We need to replicate the same information on the Remote SCADA PC which is 50 KMs from the site. So, the same screen display is to be available on the Remote PC as that of the Site PC.
For example, TeamViewer gives this kind of access. However, with TeamViewer, the person handling the Remote SCADA PC can navigate through the pages. Basically, the person has full control of the system. We would want to avoid this. The Site PC should be the MASTER and ultimately, the page (data) which is being viewed by the people on-site, only that should be available on the Remote PC. We cannot give the Remote User any Control over the Local Site PC.
Also, we would like to give 5 users access to the Local SCADA PC. So people from 5 different places to get access to the Site PC simultaneously. Again, only monitoring, but no control over the Local PC. Is this possible?
