==== Demand monitor ==== === Description === This driver produces metrics based on user defined energy consumption within a specified demand (time) window and instantaneous power reading from a connected power/energy meter. The resulting values can be used to drive demand shift automation in order to stay under demand window limits. ---- ==== Configuration settings (center panel) ==== **Name** - The name is up to the user. Our suggestion is to choose a naming convention that makes the viewing the device list intuitive. Such as referring to the sensor and/or application. Keep the name short as it will be combined with the register name to create the default "Field" name (if added to "Fields") **Active Check box** - Check this box and "Save changes" to run the driver. The driver program can be suspended by unchecking the box and clicking on "Save changes". **User Notes** - This space can be used to store information specific to the device, such as: location, wiring, scaling, etc. **eze System Notes** - In this space we provide: wiring instructions, product image, product details. ---- **Window size** - Select the number of minutes in your demand window (5, 10, 15, 20, 30, 60) **Delta-T for trend** - **Power field** - Enter the Field number for the power (kW) reading ---- ==== Status & Registers (right panel) ==== === Device Status === **Driver info** - Typically this is the name from the program file **Driver updated/version** - Date loaded or updated and the version of the driver **Battery & Signal** - Signal indicates the progress through the script. If driver fails to operate, signal number indicates progress **Driver status** - Color and text of status bubbles give a quick visual reference of Communication, Operation, and Application **Communication** - Com count indicates number of successful and unsuccessful data packets received ---- === Available registers === - Target Energy (Writable) - User defined max energy consumption for demand window - Predicted Energy - Predicted energy total based on accumulated energy and current power usage - Window energy - Current energy total for current window - Momentary power - Current power (kW) reading of user define Field - Max power allowed - Max sustained average power consumption allowable to stay within demand window limit. - Power margin - Head room between current power reading and "Max power allowed". - Time until target exceeded - Predicted elapsed time when user define target energy total will be exceeded, based on accumulated energy and current power usage - Window time remaining - Seconds remaining in demand window - Time over power budget - Number of seconds over user defined max energy, in current window. - Percent of previous window - Percentage comparison of current consumption to previous demand window.
