3. Check the CRBasic program. Create a simplified version of the program, or break it up into
multiple smaller units to test individually. For example, if a sensor signal-to-data
conversion is faulty, create a program that only measures that sensor and stores the data,
absent from all other inputs and data. Write these mini-programs before going to the field,
if possible.
4. Verify that each VOLT 100 series in the network has a unique CPI address.
5. Check the data logger and VOLT 100 series operating system and update them as needed.
6. Check that the scan rate is long enough for the measurement time. (See Measurement
speed (p. 33).) The data logger compiler often catches scan rates that are too fast.
7. Ensure that the CPI network bit rate is fast enough for the data generated and that it can
accommodate the cable lengths in use. (See CPI network bit rate (p. 36).)
12.1 CPIStatus table
Information in the CPIStatus table, located in the data logger, helps in troubleshooting. The
ModuleInfo() array shows the following information:
CDM Type, Serial Number, Device Name, CPI Address, Activity
The last entry in the ModuleInfo() index shows the activity of the module. Possible entries and
their meanings are shown in the following table.
Table 12-1: CPIStatus activity
Response Meaning
