Message_log

The message_log table contains a history of events, and is intended as a

troubleshooting tool. A record is written to this table when a predefined event

occurs, including:

• Starting/stopping the valve sequence

• Sending a command to the IRGA (configuration, zero, or span)

• Error messages related to IRGA commands

• Acknowledgement from the IRGA for these commands

• Changing the value of a system configuration variable

In normal operation, each calibration sequence with AUTO_ZEROSPAN

enabled will generate six records: send and acknowledge for each of the CO

zero, H

O zero, and CO

span commands. The memory card has space

allocated for 28,800 records (100 days with a calibration sequence every 30

min). The CPU has space allocated for 288 records.

The message_log table also includes several values to document the state of

the AP200 in case of trouble.
