Abstract
The equipment RTU (Remote Terminal Unit) monopolize much more the sphere of industrial applications which necessitate the control and monitoring from distance of the processes, stored under histories form of land events, take some measures in case of damage or alert the personal. So, with help of SCADA interface (Supervisory Control And Data Acquisition) all the process can be monitored and controlled with the help of a computer. In the paper an application created with the help of the RTU Tbox equipment is presented, application being used for the monitoring of a solar installation for the processing of hot water. The application is located in a mountain area, the solar system being made up of collectors with a surface of 2x16 mp, two 500 liter reservoirs and two heat switches.
