6 CENTO is a multifunctional software platform for data collection, processing, and display. This Guide contains a description of setting up metering of electricity, energy resources, as well as other types of metering.

8 It is assumed that the user, having read the instructions "User manual" and "Setup manual", is already familiar with the main elements of the interface and how to configure CENTO.

14 CENTO software can work with a variety of metering devices that have the ability to measure and store power and power profiles. The metering function is enabled by adding the metering protocol corresponding to the device on the **Device editing** page (Settings > Devices, tags, channels > Devices), then, similar to other polling protocols, the parameters of communication with the device (RTU address, TCP/UDP port, timeout and number of connection attempts) and scheduled polling parameters (cron of CENTO rules) are specified, to configure electricity metering, the file number is specified in the "File#" field,  which stores power and power profiles.
15
16 We will consider the survey of historical data of interval values of accumulated electricity using the example of SATEC devices. For this purpose, the// SATEC (Modbus TCP)// protocol is used (see Fig 2.1).
