The application collects the data and controls the PLCs manufactured by for example Praterm, Danfoss nebo Siemens. The communication is transmitted via radio using the innovative WMC company telemetric system. PROMOTIC as a part of the system collects and archives the data about the current state of each node (temperature, pressure, heatmeter info - devices manufactured by for example Aquatherm, Kamstrup, Siemens, Apator and water meters) into MySQL and allows to controll the regulators (automated machines operational mode switching, heating curves parameters modification, etc.) The data history is visualized as charts, that can be displayed using the Internet Explorer thanks to the integrated Web server. The WMC-NET company used the PmChar - Driver for communication by user defined ASCII/BIN protocol, allowing to adapt the data transfer inside the PROMOTIC system to the protocol used in the radio network. Thanks to this technology it is not necessary to encapsulate the data protocols as needed for another visualisation systems.
