CompoNet Master Board has two LED indicators: MS LED for Board status
and NS LED for network status. They indicate an error occurrence and the
error content.
This section explains the LED indicators and how to handle the errors. The
explanation assumes that the CompoNet Master Board has been set up
properly.
6-1-1 Identifying Errors
An error is identified in the following sequence:
1. Knowing the error
Monitor the lightning pattern of the LED Indicators. Know whether the error
is on the CompoNet Master Board (MS LED) or the Network (NS LED).

2. Identifying the error content
Read the Basic status group and the Detailed status group in the
CompoNet Master Board. Identify the error location and the content.
In the Windows operation systems, use the API functions to read the
status groups.
In other environments, access to the Shared memory area.

3. Detecting the error cause
Compare the Error occurrence factors and the on-site situation. Detect and
eliminate the cause.
↓
4. Solving the error.

and the required operation for solving the error on the Action to be taken.
Reset the system operation to normal.
The subsequent sections explain the error identifying function on the
CompoNet Master Board, the operation after detecting an error and the
actions to be taken.
