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.

107 107  Metering can be implemented not only on the basis of specialized metering devices, but also performed in the CENTO software itself on the basis of tags (real-time data). For example, using information about the state of the equipment (0 - disabled and 1- enabled), the user can set up a metering channel that will calculate the operating time of the equipment. And using the processing functions (see Section 5 of this manual), you can form metering channels (increments) from the current capacity, instantaneous flow or an ever-growing meter.

To do this, you hover the cursor over the desired cell in the table, perform a left click of the mouse and enter a new value, after which the save value icon appears on the right side of the input field [[image:Screenshot 2025-11-30 at 16.51.39.png]]. Press it or //Enter// on your keyboard, and the value goes to the CENTO database. For devices where only manual data entry is provided, CENTO has developed a procedure for filling the cells between two manual entries. If readings are recorded at 10:00 a.m. and then again at 8:00 p.m., the system automatically fills in the readings for all intermediate intervals. For electricity metering channels, the system additionally calculates and populates the corresponding energy and power values.

291 +The **Download** button allows downloading the selected metering channels to the User's computer in .xlsx format. The downloaded file can be used for manual entry of metering data. To perform manual entry, open the file in the editor. Then enter new data in the fields, mark them **in bold** and save the file [[image:Screenshot 2025-11-30 at 16.52.15.png||height="25" width="66"]] in the CENTO interface.
