Error Log Section 6-2
6-1-4 Error Identification by StateStatus
The errors monitored by NS Indicator lighting or flashing are identifiable by
StateStatus of the Basic status group.
In the Windows operation systems, use the function CPNT_GetStatus to
access the Basic status group.
In other environment, access to the shared memory area directly.
6-2 Error Log
The Error log keeps record of the errors and occurrence time when the
CompoNet Master Board detects an error. The records (or error log) can be
read or cleared by the Detailed status group.
6-2-1 Error Log Table
Error Log Table Errors are saved in the Error Log Table in the CompoNet Master Board RAM.
One error is counted as one record in the table. A maximum of 64 records can
be saved. When the table is full with 64 records, the oldest error record is
discarded to replace it with the next coming error.
The Error Log Table saves the following information:
• Error code,
• Detailed code, and
• Date when the error occurred (this data uses the time information notified
by the user application)
