The equipment RTU (Remote Terminal Unit) monopolize much more the sphere of industrial applications who necessities the control and monitoring from distance of the processes, stored under histories form of land events, take some measures in case of damage or to alert the personal. So, with help of SCADA interface (Supervisory Control And Data Acquisition) all the process can be monitoring and controlling with the computer help. In the paper an application created with the help of the RTU Tbox equipment is presented, application 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.. It also presents an application for monitoring and control of a production line, made from 16 hydraulic presses, with the help of software SCADA Ethernet Tview. Because the major products realized by beneficiary (hub from auto) get to the export where the customs want a strict monitoring the times of vulcanization, of the temperatures and pressures uses, it is necessary to search the best solutions who permit a production control from computer and who can accomplish some conditions impose. Obs.: The final results will be presented through online link, with authors' access only.
The industrial control systems, which include supervisory control and data acquisition (SCADA) systems, distributed control systems, and other smaller control system configurations such as skid-mounted programmable logic controllers are often used in the industrial control sectors. The SCADA systems are generally used to control dispersed assets using centralized data acquisition and supervisory control. The SCADA systems are also distributed systems that are used to control geographically dispersed assets, which are often scattered over thousands of square kilometers, where centralized data acquisition and control are critical for system operation. They are commonly used in distribution systems such as water distribution and wastewater collection systems, oil and gas pipelines, electrical power grids, and railway transportation systems. In this article, the SCADA system used in the Yuvacik Dam and Reservoir operation, which is located in Kocaeli province of Turkey is reported and the problems associated with the system operation and their solutions are discussed.

The Monitoring and Control System for the Real Equipment Controlled by PLC
2002
The paper is focused on an application of commercial systems for visualisation and control of technological processes. These systems are designed for data visualisation. The data are measured by a programmable controller. The systems InTouch, Wizcon and ContolWeb2000 were used. Monitoring and control system was tested on the real equipment. The programmable controller controls the surface of two communicating vessels and at the same time is a data source for master applications that are designed for the systems InTouch, Wizcon and ContolWeb2000. The contribution also describes visualisation systems and serial communication for Windows and gives the description of the ModBus protocol.
POSSIBILITIES OF COMMUNICATION IN INFORMATION AND CONTROL SYSTEMS
Control Systems (ICS), focused on visualization and control SCADA/HMI systems. It describes the way of the communication between Suite Voyager Industrial Server and external devices or models. It contains descriptions of configurations and description of structures which we have built in our department. We also describe communication protocols which we use and combine in our solution. At the end, these possibilities are compared and there are described our practices.
