Example: Connect a pressure sensor to channel 0 of an analog input module and change the SNVT type
Sensor specifications
1. Use the LonMaker Browser to change the SNVT type of nvoAI0.
On the LonMaker Browser screen, right-click on the network variable line. From the short-cut menu, select [Change
Type], then select “SNVT_press.”
2. Set the nciMinRng[0] and nciMaxRng[0] values as shown below.
When the analog input module receives an analog value of 20 kPa (4 mA), the analog input module sends nvoAI0 data rep-
resenting 20 kPa to the network. Similarly, when receiving 50 kPa (10 mA), the analog input module sends nvoAI0 data
representing 50 kPa.
Measurement Range 20 to 100 kPa
Analog Output Value 4 to 20 mA
