Abstract: The most widely used networks for data communication are TCP/IP networks. One of the application areas is the remote data acquisition in power engineering, where the consumption of electric power is read in so-called continual metering. Electrometers can be connected to the TCP/IP network by means of the communication unit. Thanks to the communication unit, remote acquisition of power consumption data is enabled. This article focuses on the connection and the methods of testing of communication unit in an experimental network. The article also deals with the design of the authentication, secure data transmission, and transmission block integrity.
