7/10
REGISTER 29 – BATTERY POWER
It has the value of measuring the voltage level of the battery in engineering
unit. The decimal point is fixed in three houses. The value is without the
point and must be predicted by the reading software. Reading the battery
voltage may show an error of up to 5 %.
Typically, a battery with 100 % of its load has voltage above 3.6V.
Depending on the use of
RHT-Air
, the battery will gradually decrease
voltage. It is recommended to periodically check the value of this register so
that, when it reaches values below 3.3 V, a battery change is scheduled.
Checking the battery capacity can be done using the
Diagnostics
tab of the
DigiConfig
software, which will display an icon. The evaluation of battery
capacity can be performed according to the criteria presented in the table
below:

Bad – Replace the
battery as soon as
possible.
NOTE 1
: Even when the power is below 100 %, the device will operate normally.
NOTE 2
: The gradual failure of the battery power is not linear, therefore, though the device
is able to continue working under tensions below 3.0 V, when it reaches this level, there is
little left for its life, since the power will fail more quickly.
NOTE 3
: While the device is being powered from an external source, you may notice a
slight rise in battery voltage. This is because the battery voltage increases whenever power
from the same battery is not being consumed.
NOTE 4
: The machine operating temperature has a significant impact on the battery
capacity. Temperatures below 0 °C will typically shorten the battery life.
NOTE 5
: Battery chemistry is directly affected by the ambient temperature. High
temperatures tend to raise battery voltage, as low temperatures tend to decrease
battery voltage. In both cases, autonomy is negatively affected.
NOTE 6
: The update time, as well as the operating power, have a significant impact on
the battery capacity. If the device is configured for the lowest update interval, the
battery will typically last less. The same happens when the device is far from the
AirGate-Modbus
with which it should be matched, needing a higher transmission
power to operate.
NOTE 7
: Remove the battery or insert the insulation film when the device is not in use.
Leaving the powered device out of range of a Wireless network will cause the device to
continually attempt to pair, which may lead to premature battery death.
REGISTER 30 – LAST POLL DURATION
Every time
RHT-Air
publishes something on
AirGate-Modbus
, this register
gets a zero value. Every 100 ms, this register is increased in 1 unit to
indicate how long it has been since the last publication.
REGISTER 31 – MODBUS ADDRESS
It sets the address of the device on the Modbus network. This address
identifies the device on the Modbus network. Its configuration may range
from 1 and 247. There cannot be more than one piece of device with the
same address on the same network.
RHT-Air
is originally manufactured with
the address 246. When connected to a USB interface, it always responds to
Modbus functions through the address 246. When it is in operation, it always
responds through the address it was configured for in this register according
to the communication parameters of the Modbus network on which it was
installed.
REGISTER 32 – UPDATE TIME
It sets the configuration for how often the device wakes to publish
information on the
AirGate-Modbus
with which it is matched and update the
IHM screen.
The shorter the update time, the more recent the data available to the
master of the Modbus network will be, but the higher the energy
consumption spent, and the battery life will be proportionately shorter. On
the other hand, the higher the update time set, the lower the energy
consumption spent will be, thus providing a longer life for the battery.
REGISTER 33 – INDICATION MODE
It sets the mode of indication of the values read on the display. The device is
originally manufactured with the indication of temperature and relative
humidity.

REGISTER 36 – USER OFFSET FOR TEMPERATURE
It sets the users’ offset value in engineering units for temperature. The
device offset value is originally zero.
REGISTER 37 – USER OFFSET FOR HUMIDITY
It sets the users’ offset value in engineering units for relative humidity. The
device offset value is originally zero.
REGISTER 38 – ERROR VALUE
It contains the error value that is transmitted when the sensor has a problem.
The device original value is -9999.
REGISTER 39 – TEMPERATURE VALUE (°C or °F)
It contains the value of temperature measurement in an engineering unit,
including the users’ offset corrections for temperature. The decimal point is
fixed in one place. The value has no point and must be provided in the
reading software.
REGISTER 40 – RELATIVE HUMIDITY VALUE (%)
It contains the value of relative humidity measurement in an engineering
unit, including the users’ offset corrections for temperature. The decimal
point is fixed in one space. The value has no point and must be provided in
the reading software.
REGISTER 41 – DEW POINT VALUE (°C or °F)
It has the value of the measurement in an engineering unit. The decimal
point is fixed in one place. The value has no point and must be provided in
the reading software.
