The subroutines GetChannelValue_iNet() and SetChannelValue_iNet() are used to read and write instruNet channels with one scalar value. They typically require 50 to 300us to execute. They contain 4 arguments that specify an instruNet channel address, and then a value that is read or written, in engineering units. For example, if channel {1,1,1,1} is connected to a thermocouple at 30C, then:

x = GetChannelValue_iNet(1,1,1,1,&errorCode)

will fill variable x with 30. These routines are exposed through the iNet32.DLL and through the INET_INT.C interface file; and are documented in file INET_INT.C. An example use of these functions in C is shown in file INET_EX3.C. Prototypes for these two functions can be found in INET_MCS.H.

The subroutines GetFieldValue_iNet() and SetFieldValue_iNet() are are similar, and are used to read and write fields within each channel (e.g. sensor type, filter settings, etc). For example, the following C code would set the sensor type on channel {1,1,1,1} to "current".

err = SetFieldValue_iNet(1,1,1,1,sgt_VinHardware,
  fldNum_Vin_sensorType, ion_SensorType_Current);

The constants that address the various fields can be found in file INET_INT.H.
