Figure 5-5-4. Host-Watchdog Demo.
After 5 seconds, the "host is down" message pops up.
Click on the “OK” button to close this message box.
Since the Host-Watchdog is enabled, if the Host PC does not send the
command “~**” to the module, the module supposes that the Host PC may
break down
. All output commands will be ignored when the module is in
safe state.
Figure 5-5-5. Host is down. Module goes into safe state.
After the module goes into safe state, the module’s Host-Watchdog will
be disabled automatically. Click on the “Clear [Host failure mode]” button to
clear this status (refer to Figure 5-5-5). The module’s status will go back to
“0:Host is OK!” (Refer to Figure 5-5-3).
