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:
164 -
165 -* ea_imp - energy A+
166 -* ea_exp - energy A-
167 -* er_imp - energy R+
168 -* er_exp - energy R-
169 -* pa_imp - power A+
170 -* pa_exp - power A-
171 -* pr_imp - R+ power
172 -* pr_exp is the power of R-
173 -* ra_imp - A+ readings
174 -* ra_exp - A- readings
175 -* rr_imp - R+ readings
176 -* rr_exp - R- readings

178 -5.3.  Calculated channels via Information Model
179 -
180 -For calculation channels of the same type, it is possible to define custom formulas that operate based on Information Model objects and their attributes. In addition to tags and channels, the Information Model can also supply supplementary data (e.g., reference information). To create a template, click the create template button [[image:Screenshot 2025-11-30 at 16.36.34.png||height="27" width="26"]] as shown in Fig. 5.4.
