(6) Precautions for executing Shell commands from Tornado Shell or the
Telnet tool
1) When executing the Shell command from Tornado Shell, pay attention to the
following since the entered Shell commands operate on the task of priority 1 in
the C Controller module.
• Only alphanumeric characters and special characters can be used.
• Some commands, such as those exclusively using the CPU module and
those including characters other than alphanumeric characters and
special characters, may be regarded as a command causing a watchdog
timeout error, a control code (such as "CTRL + X"), or being garbled. As a
result, a system error, such as a system watchdog timer error, or stop may
occur in the C Controller module. Pay full attention to the command when
entering it.
A VxWorks message may appear on the Telnet tool screen during a Telnet
connection to the C Controller module.
For messages of VxWorks, refer to the manual for VxWorks or Tornado.
2) When executing the Shell command from the 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.
When exchanging the Telnet tool with another, first close the connection with
the currently used Telnet tool, and then connect the line to the C Controller
module from another Telnet tool.
Pay attention to the following since the Shell commands entered by the Telnet
tool of the development environment (personal computer) operate on the task
of priority 2 in the C Controller module.
When using Shell commands, pay attention to the following.
• Only alphanumeric characters and special characters can be used.
• Some commands, such as those exclusively using the CPU module and
those including characters other than alphanumeric characters and
special characters, may be regarded as a command causing a watchdog
timeout error, a control code (such as "CTRL + X"), or being garbled. As a
result, a system error, such as a system watchdog timer error, or stop may
occur in the C Controller module. Pay full attention to the command when
entering it.
A VxWorks message may appear on the Telnet tool screen during a Telnet
connection to the C Controller module.
For messages of VxWorks, refer to the manual for VxWorks or Tornado.
