Appendix B. Example programs

These programs were written for a GRANITE 6 data logger, except where noted. With slight
modifications, they can be used with other Campbell Scientific data loggers.

NOTE:
For the GRANITE 10 and GRANITE 9 data loggers, the

CPIBusAddress

parameter must

include the CPI bus when using bus B. Bus A is the default. For example,

CP 2

specifies CPI bus B and CPI address 2.

B.1 Configuring GRANITE Measurement
Module with

CPIAddModule()

The following program sets CPI addresses and device names on TEMP 120s with serial numbers
1234, 1235, and 1236 and makes 15 Type-T thermocouple measurements on each module.

CRBasic Example 2: Using CPIAddModule()

'GRANITE 6 Datalogger

'measures 15 input channels on each device.
