Transmitting data over the network using an OPC server

Abstract

The paper presents the way of transmitting the parameters of operation of a remote installation in a centralized control center of a company. The distance between the computers that collect the data and the data monitoring center is hundreds of kilometers. Data has to be transmitted through multiple physical environments and through multiple networks. This transmission channel must be very stable and secure against external threats to the company network. The monitored installation is comprised of 10 compressors each having a local control cabinet and transmitting data to monitoring computers in the control room. Centralized data in these computers are sent to the beneficiary. This transmission uses a tunneling solution provided by a company together with an OPC Server realized by using that function of the software in which the monitoring application is developed on the industrial computers in the control room of the respective installation. The results obtained in remote data transmission were very good. In conclusion, the configuration and software solutions adopted proved reliability and stability in operation.
