Delaying Setpoint Operations
Two optional delays can be added to each setpoint to extend monitoring a setpoint trigger for a longer time
before making a decision on whether the expected event occurred or not. When a delay is specified, the
logical controller will change the setpoint status only if all conditions are asserted for a period at least as
long as the delay time.
Using Setpoint Events
When a setpoint status changes, i.e., a setpoint event is either asserted or de-asserted, the following
happens in your device:
1. The new setpoint status is logged to the setpoint status register that can be monitored via
communications from the user application software in order to give a real-time indication on the
expected event.
2. The operated setpoint status is latched to the setpoint alarm register accessible through
communications. The register holds the last setpoint alarm status until it is explicitly cleared via
communications.
Recording Setpoint Events
Time-tagged setpoint events can be recorded to the submeter event log if you select it as the setpoint
action. The Event recorder logs any setpoint transition event: both when the setpoint is operated, and
when it is released.
4.7 Configuring Billing Energy and TOU Registers
The BFM136 provides four total/summary energy and six parallel tariff energy and maximum demand
registers for each individual submeter. The registers can be linked to any internal energy source or to
another submeter.
The meter tariff structure supports six different tariffs using an arbitrary tariff schedule. A total of four types
of days and four seasons are supported with up to eight tariff changes per day.
The meter can provide automatic daily profile recording for total and tariff energy and maximum demand
registers. The device memory is sufficient to store daily profile data for 120 days.
By default, the first billing register in your meter is linked to the kWh IMPORT accumulator, and the daily
profile recording is enabled for the kWh register. Other billing registers are not operational. To activate the
remaining registers or to change the profile for the first billing register:
1. Link the Summary/TOU registers to the respective energy sources, and then configure the options
for these registers like whether the only totalization or both total and tariff registers would be used,
and whether daily profiling should be enabled for the energy usage and maximum demand
registers.
2. Configure the daily tariff schedule for all types of days and seasons using the TOU daily profiles.
3. Configure the season tariff schedule using the TOU calendar.
