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.
Bit “1” The scan data of the corresponding scan block was unhealthy
before.
Bit “0” not unhealthy before
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 data
of the block is received within the diagnosis
time determined based on the scan sending
cycle set for the block.
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.
Note
•
When clearing the scan unhealthy map to zero, be careful not to clear other areas by
mistake.
