User can change?

MSPClkFreq(3) MSP430 CPU #3 RC oscillator frequecy in Hz No

MSPClkFreq(4) MSP430 CPU #4 RC oscillator frequecy in Hz No

MSPClkFreq(5) MSP430 CPU #5 RC oscillator frequecy in Hz No

CalOffset Calibration offset voltage No

VarOutOfBounds Number of times an array was accessed out of

bounds

Yes (clear to zero)

SkipScan Number of skipped scans that have occurred while

running the current scan. When making the vibration

wire measurement it is normal for the skipscan's to

increment

Yes (clear to zero)

TrapCode A code number that describes the last watch dog

event that has happened (updated at power up).

Yes

WatchDogCnt Number of Watchdog errors that have occurred

while running this program

Yes (clear to zero)

ResetTables Not Used Yes (function disabled)

BattVoltage Current value of the AVW200 battery voltage (value

updated every 8 sec).

Yes

SRAMMemSize Size of the SRAM memory No

The SRAMMemSize parameter was added to OS version STD.02.

Older modules have 128 Kbytes of SRAM and newer modules

have 512 Kbytes of SRAM.

If the SRAMMemSize = 512 K, then the AVW200 will create and overwrite a

file for every measurement on each channel. The files are called TS_chan1.bin

and TS_chan2.bin. These files have the 4096 samples or TimeSeries data for

the last measurement. These files can be retrieved using LoggerNet

FileControl or the datalogger instruction GetFile(). A post-processing program

in DevConfig under device type AVW200 Series called “Off Line Analysis”

can be used to analyze the files.
