103 103  
104 +
105 +In addition to metering electricity and energy resources, the CENTO software supports tracking of operating time, emissions and discharges, as well as product accounting.
106 +
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.
108 +
109 +== 5. CALCULATED CHANNELS ==
110 +
111 +If the device installed at any connection does not have the function of storing interval values of electricity/power in the memory, as well as archived values for other types of metering, CENTO has the function of generating interval values from tags (real-time data). In order to create a metering channel, go to Settings > Devices, tags, channels > Calculation channels (see Fig. 5.1).

120 +
121 +Then the **Channel from tag:**

162 +
163 +In the **Template** field, specify the formula for processing the values of all parameters used in the calculation. The formula can use arithmetic operations, conditions, mathematical functions that are specified in [[image:Screenshot 2025-11-30 at 16.35.23.png||height="30" width="135"]] and the following variables for power channels:
