6 Commands and meter data
6.1 Ad hoc (Immediate) Reads
The meter will respond to requests for Ad hoc register reads. The meter will
respond immediately with the requested data. The ad hoc read request
may consist of any metering parameter held within meters memory.
As an example a standard request may consist of:

MPAN/Cust #

Electricity Meter Serial Number
 Rate 1 kWh register
 Rate 2 kWh register
 Rate 3 kWh register
 Rate 4 kWh register
 Total kWh register

Export energy register.
Automatically the meter will return the following data in the return message
header:
 Electricity Meter Status

Date and Time stamp
The above data would fit within a single SMS message.
6.2 Change of Tenancy/Supplier
The meter is capable of handling changes in tenancy or supplier by zeroing
or revaluing various registers within the meter upon receipt of a change of
tenancy/supplier command (CoT/S) by the system.
A CoT/S command can be configured to operate either immediately or at
some time in the future; the CoT/S command will contain an activation date
and time for when the process should occur. The meter will only perform
the operation at the configured date and time unless requested
immediately.
The CoT/S command is able to change or zero the following registers/
features:

Reset or overwrite Credit/Debt register, configurable from 0 to
maximum top-up value.

Where the meter is in emergency credit the EC and any DCLR
value will be cleared.

Reset or overwrite Total Debt register, configurable from 0 to
maximum value.
