1) TWhen executing Shell command from Tornado Shell
When executing the Shell command from Tornado Shell, the entered Shell
command operates on the task of Priority 1 in the C Controller module.
Care should be taken since a system error/stop (such as a system watchdog
timer error) may occur in the C Controller module depending on the entered
command (example: command that occupies CPU processing).
2) When executing Shell command from Telnet tool
Make one-to-one connection between the Telnet tool and the C Controller
module.
Connection cannot be made from multiple Telnet tools to the same C
Controller module.
The Shell command entered with the Telnet tool of the development
environment (personal computer) operates on the task of Priority 2 in the C
Controller module.
Care should be taken since a system error/stop (such as a system watchdog
timer error) may occur in the C Controller module depending on the entered
command (example: command that occupies CPU processing).
3) Execution of VxWorks reboot command
Do not reboot VxWorks by executing the reboot function or pressing the CTRL
+ X keys.
If VxWorks is rebooted, the C Controller module does not start up properly.
Refer to Section 4.5.3 or Section 13.6 for how to reset the C Controller
module.
4) Execution of command without argument specified
If a command having an argument was executed without the argument
specified, it means that the command was executed with 0 specified as the
argument. Depending on the executed command, a system error/stop (such
as a system watchdog timer error) may occur in the C Controller module.
Before executing a command, be sure to confirm the specifications and
specified argument of the command.
Example) Do not execute the "close" command without the argument
specified. To do so will close the resource reserved in the VxWorks
system.
