12.5. ADDING AND REMOVING OF MEASUREMENT SENSORS TO AND FROM A LIST
As a default, the device is delivered with an empty list of measurement channels. For the purpose of presentation
of data, new channels must be added to the list that are assigned to the radio sensor of the AR43x series and/or
Apar devices connected to the RS485 line and/or the AR182/AR183 temperature probe. Selection of the serviced
interface (radio, RS485, or probe) for each of the channels is set with parameter
Assigned sensor type
(in the
Measurement channels
configuration menu; a detailed description can be found in chapter 12.4).
In a correctly configured system, all measurement channels of the same type (radio sensors or RS485 devices)
should have their own unique identification numbers (ID or MODBUS-RTU address, set with the
Address of
assigned sensor ID
parameter, chapter 12.4).
When the
Assigned sensor type
=
RS485 (MODBUS-RTU)
, it is also necessary to configure the
Decimal dot
position
and the
Register address to read for RS485
(e.g. 16-bit measurement with a character, according to the
map of MODBUS-RTU registers of the connected device that is available in its user’s instruction) and in the
Communication settings
(chapter 12.8), set the
RS485 operation mode
parameters to
Master
and the
Baud rate
for RS485
to one that is compatible with the device.
If the
Assigned sensor type
=
Radio (AR43x)
, then the measurement channel adding or deleting procedure
follows the description below.
Before the wireless sensors adding procedure is started, make sure that all devices of the configured system work
on the same radio channel number that is different than that of the neighboring radio networks that are in the
range (as a default - channel 6; the larger the number, the better; see chapter 12.8).
1.
There are two ways to add radio sensors to the list (indexing):
a)
automatic (initiated with the
ADD/REF/OFF
button in the AR43x sensor)
NOTE:
Radio sensors
must
be indexed individually!
The start
of the procedure to obtain an index (
ID
) is indicated in the sensor by a single momentary
illumination of the
Status
and
RX/TX
diodes, which takes place after the
ADD/REF/OFF
button is pressed.
The end
of the procedure takes place when the “
New radio sensor was registered
” or “
No available channels.
Provide unused ones.
” message is displayed on the AR407 display.
After the message is closed with the
[SET]
or
[ESC]
button, one can start indexing another sensor, unless the
list is full (a maximum of 16 channels). In the event of a failure, the procedure must be repeated
. The
maximum duration of the procedure is approximately 35 seconds
.
In the case of indexed 2-channel sensors (AR433/434/435/436/437), it is possible to delete the second channel
from the list of the AR407 recorder (parameter
Address of assigned sensor (ID)
=
None
=16 in the
Measurement channel
configuration menu, chapter 12.4), e.g. in order to switch this channel off or make it
available to another sensor.
NOTE:
!
At the same time, if the procedure is started on several sensors, they are assigned the same
ID
address
(number) and, as a result, they are assigned to the same measurement channels in AR407 (the data will be
