Chapter 7 Application Interface

7.2.2 Configuration of the scan data unhealthy map

The scan data healthy map is managed in the configuration as shown in
Figure 7-6.
The scan data healthy map shows the state history information of the
corresponding scan data blocks.
In the scan data healthy map information, the information of the block is
ON when a healthy state of the block is detected, and the information of
the block is not OFF when an unhealthy state of the block is detected.
Unhealthy detection condition: An unhealthy state is detected if no scan
The diagnosis time is set to 500ms if the value four times the scan sending
cycle is less than 500ms. If it is greater than 500ms, the diagnosis time is
set to the value four times the scan sending cycle (rounded up to the
nearest 10ms) (three cycles are diagnosed).
The scan data unhealthy map indicates whether the block has become
unhealthy one or more times after the scan data unhealthy map is cleared
to zero.
