LoRa Node
32
2.3 I/O Configuration
In the I/O Configuration screen, you can configure the Analog Inputs (AIs) and Digital Inputs (DIs). There are 3
sets of AIs and 2 sets of DIs.
According to the hardware configuration you already finished, you have to further configure the settings for
the device firmware, so that the Data Logger will know what kind of input device is connected to each port.
For Analog Input ports, you can specify an optional
Name
for identification, and the
type
(
0-10V
, or
4-20mA
)
for each connected port. And then click
Enable
check boxes for those connected ports.
For Digital Input ports, you can specify an optional
Name
for identification, and the
Mode
(
Dry Contact
, or
Pulse Counter
) for each connected port. And then click
Enable
check boxes for those connected ports.
If
Pulse Counter
mode is selected, some additional fields (
pulse type
and
Offset
value) have to further define.
Pulse Type
: It can be
Change
,
Rising
, or
Falling
. On each pulse event, the corresponding internal
counter will be increased by 1 automatically.
Offset
:
Enter the Offset value for initial reading of the connected device (pulse meter). It is very
likely that the initial reading for the connected device is a non-zero value, so you have to
enter the initial value as an offset for the further readings.
With the settings, the LoRa node will activate 32-bit counters to count the pulse behavior, record the counter
value plus the Offset as the actual value on each data upload time slot.
