Command mode overview

You can use this mode to send a Modbus command to the device which sets the active tariff. This tariff is applied to the measured energy until you send another Modbus command that sets a different tariff.

Time of day mode overview

You can use this mode to create a tariff schedule that specifies where the meter stores energy or input metered data, based on the time of year (month, day), the type of day (every day, weekend, weekday or a specific day of the week), or time of day. The data collected from the different tariffs can then be used in energy audits or similar costing and budget planning purposes.

Time format

Multi-tariff configuration using the front panel uses this date and time format:

Tariff validity

A valid tariff has certain conditions and limitations:

•Each tariff must cover a unique time period (tariffs cannot overlap) but there can be periods with no tariff.

•Any number of tariffs, from none to the maximum number of tariffs, can be applied.

•Time of day tariffs do not adjust for daylight savings time.

•Time of day tariffs include February 29th in leap years (however, it is not recommended to have February 29th as a start or end date, as that tariff would be invalid for non-leap years.

•Except for leap years, tariff dates are not year-specific; if you wanted to create a tariff that starts on the first Monday in August, you need to enter the date for that year, then manually update the tariff information for the subsequent years.
