Syntax
error_code SMADCSetSensorType(u_int8 PortNr, u_int8
channel, u_int16 sensorCode);
Description
This function checks if an SM-THERM board is fitted on the specified port,
if the channel is valid, if the sensorCode is known and sets the gain, preci-
sion and mode to their default values for the type of sensor connected.
Input
u_int8 PortNr
Port number om module to set
(from 0 to 10)
u_int8 channel
Number of specified channel (0 to 3)
u_int16 sensorCode
Code of the sensor (a list of PEP
defined sensor types can be found in the
file linear.h)
Output
error_code SUCCESS
E_MNF
If wrong type of module or no module
is fitted on the selected port
E_PARAM
If wrong channel number is specified
E_BTYP
If sensor type is not known
or standard OS-9 error code (refer to the OS-9
Technical Manual Error Codes Section).
