SDI-12 Smart Sensor Configuration
Smart sensors using either SDI-12 or Modbus can be connected, and values can be transmitted
through the Condor wireless network.
SDI-12 smart sensors are often used with environmental or agricultural sensors such as weather
stations (wind speed, direction, rain fall, temperature, humidity), water quality and ground moisture
measurements. The 415U-1-Cx allows these SDI-12 sensors to be connected and their internal
variables to be transmitted via the Condor wireless network.
By accessing the Smart Sensor menu from I/O setup, the configuration allows SDI-12 sensors to be
added and variables configured to be sent over the 415U-1-Cx communications port.
TIP:
If you are adding multiple sensors to the SDI-12 port it is best to connect one sensor at a time and
use scan to add sensor measurement variables, change address to unique value. Then connect the
next sensor, use add sensor option, change address, and so forth until all sensors are added.
The SDI-12 configuration menu has the following options:
SDI-12 config Menu:
Description
a) Select Smart Sensor SDI-12 or
Modbus: SDI-12
Switch between SDI-12 and Modbus Smart Sensor options.
Note that only one type can be used at a time and all
mappings need to be deleted to switch types.
b) Scan for Device
Send out address query to identify any connected sensor
and then automatically add sensor found.
c) Manually add Device
Send manual commands to sensor diagnostic
d) Send manual command
Send manual command to add sensor. Use this option if
more than one sensor connected to bus.
e) SDI Sampling Time
Configure the SDI sensor system sample time in minutes
and warmup time in seconds. This is common for any
connected sensors and warmup time should be configured
to allow for slowest sensor.
f) SDI Measurement CMD
Change the measurement command from default (M!) to
R! or to use CRC with MC! or MR! commands. Leave at
default if unsure.
g
)….o) Setup Sensor AA ID
As sensors are added with address AA and ID using Scan or
Manual Add menu options the menu to grow more
options for the setup of each sensor.
Eg.
f) Setup Sensor 5 5ELPROTECH##0000011.0001
When selecting automatic scan for a connected sensor the 415U-1-Cx will power the sensor and then
send an address query command using the default warmup time. For very slow sensors you may need
to adjust this longer to get a response. The Scan for Device option will take quite some time as it
powers sensor, waits for the warmup time (default is 20 seconds), then request address, number of
measurement variables and waits the measurement time to get current measure variable values.
Once the scan for device process is complete the sensor configuration menu is opened. See below for
an example of the process of automatic scanning for an SDI-12 sensor.
Scan for Device:
Warming up the Sensor...
Getting SDI Params structure (address, time, variables,)....
Sending C! Command...
Response return (atttnn): 500509
The response above from the SDI-12 indicates the sensor address, number of variables available to
use.
The available SDI-12 variables are loaded then the sensor configuration menu will be show as below:
