1127h 1 Tariff managed via serial
communication
UINT 16 Writing in this cell, the multi-
tariff can be managed via serial
communication, excluding any
influence of the digital
inputs(only if the digital inputs
are not set to tariff selection).
To set a tariff, a frame including
the following information is to be
sent. LSB: 5Ah al
ways; MSB: tariff
(value from 0 to 3).
NOTES:
a) Except for external meters, if 2 or more digital inputs are linked to the same meter, it is
enabled only the first meter having that selection.
b) If 2 inputs are set in Sync mode, the switching of any of the inputs is considered as a
synchronisation signal.
c) If only one of the inputs is set in Tariff mode, only tariffs 1 and 2 are managed.
d) If the tariff is selected by RS485, only the 4 tariff mode is managed.
