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.
