Table 15 – Modbus holding register map for iRIS sensors
3.7.2
Example of iRIS acting as a Master
This section describes how to use iLink to configure the iRIS to obtain information from a fictitious sensor that measure
wind speed, wind direction and temperature. Real sensors will have a different register map etc. and please refer to the
sensor manual.
The example also assumes that the sensor has been wired to the Serial Sensor Interface which has been configured
appropriately.
1. Connect to the iRIS with iLink and navigate to the configuration section.
2. Expand the
MODBUS DEVICES
branch and select the
+ ADD MODBUS DEVICE
option.
3. Give the device a name, this is used in the Virtual sensor configuration later.
4. Change the following:
