3.5.1 Setting the self healthy mode parameters
In the self healthy mode, the talker block of the node becomes scan healthy
even if an error occurs in the transmission path. In normal operation of the
JTNI, all scan blocks become unhealthy if an error occurs in the transmission
path due to disconnection. If the JTNI is set to the self healthy mode, the
scan healthy information of the talker block of the node stays in the state
when an error occurred in the transmission path.
To set the JTNI to the self healthy mode, do the following.
In the parameter screen of the JTNI, set the option switch to ON and
perform a download.
The following table shows the scan healthy information that is provided by
the JTNI in the self healthy mode to the host controller.
