``abnt_codi`` ABNT CODI
|
||
=======================
|
||
|
||
The ABNT CODI is an old energy meter standard used in Brazil.
|
||
|
||
This code interprets the end user serial output existent in the energy meter.
|
||
That output externalizes its data blinking an LED as a serial protocol at the
|
||
baudrate of ``110 BPS`` and uses ``8`` octects:

Octet Bits Description
|
||
======= ======= =================================================================
|
||
``001`` ``0-7`` Number of seconds to the end of current active demand (``LSB``)
|
||
``002`` ``0-3`` Number of seconds to the end of current active demand (``MSB``)
|
||
``4`` Bill indicator. It is inverted at each demand replenishment
|
||
``5`` Reactive Interval Indicator. Inverted at end react interval
|
||
``6`` If ``1`` means the reactive-capacitive is used to calculate ``UFER``
|
||
``7`` If ``1`` means the reactive-inductive is used to calculate ``UFER``
|
||
``003`` ``0-3`` Current seasonal segment: ``0001`` – tip, ``0010`` – out of tip, ``1000`` – reserved
|
||
``4-5`` Type of charging indicator (flag): ``00`` – Blue, ``01`` – Green, ``10`` – Irrigators, ``11`` – Other
|
||
``6`` Not used
|
||
``7`` If equal ``1`` means reactive rate is enabled
|
||
``004`` ``0-7`` Number of pulses for active energy of cur dem interv (``LSB``)
|
||
``005`` ``0-6`` Number of pulses for active energy of cur dem interv (``MSB``)
|
||
``7`` Not used
|
||
``006`` ``0-7`` Number of pulses for reactive energy of cur dem interv (``LSB``)
|
||
``007`` ``0-6`` Number of pulses for reactive energy of cur dem interv (``MSB``)
|
||
``7`` Not used
|
||
``008`` ``0-7`` Inverted bits of _xor_ from previous octects
