The MeternetPRO program enables remote reading of the states and indications of meters, multimeters, measuring transducers, input/output expansion modules and other measuring devices communicating in accordance with the Modbus RTU protocol. Data exchange between the devices and the application is carried out via the RS-485 network or the local LAN network. The program together with the database is installed on a special MT-CPU-1 server, which works in the local network. The software user interface is a web application (web page). The program can be accessed via any web browser. In the case of a LAN with a public IP address, it is possible to configure the program and read data via the Internet.
