Precautions for program debugging
(1) VxWorks image file
(2) Precautions for executing Shell command from Shell of Tornado or from
When debugging the user program with Tornado in the development environment
(personal computer) connected to the C Controller module, it is necessary to specify
the VxWorks image file "vxWorks_XXXXX-Y" whose function version is identical with
the first five digits of the C Controller module's serial No.
(a) Confirmation before debugging
When debugging the user program using Tornado, make sure that the VxWorks
image files in the system memories of the development environment (personal
computer) and C Controller module are matched. (
10.2.6(1)(b))
(b) When VxWorks image files are not matched
When the VxWorks image files in the development environment (personal
computer) and C Controller module are not matched, copy the VxWorks image file
from the system drive (/SYSTEM/OS_IMAGEFILE) of the C Controller module to
the development environment (personal computer) using FTP.
( Section 10.2.7)
(c) If connection is made with different VxWorks image files specified
If connection is made with different VxWorks image files specified, a system
watchdog timer error may occur in the C Controller module.
In addition, normal debugging cannot be done. (
Telnet tool
(a) When executing Shell command from Shell of Tornado
In the case of the Shell command execution from Shell of Tornado, the entered
Shell command runs on the task of Priority 1 in the C Controller module.
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), special care must be taken to the entered
command. ( Section 10.2.6)
(b) When executing Shell command from Telnet tool
When executing the Shell command from the Telnet tool, make one-to-one
connection between the Telnet tool and the C Controller module.
Connections from multiple Telnet tools to the same C Controller module are not
allowed. ( Section 4.16)
A Shell command entered with the Telnet tool in the development environment
(personal computer) runs on the task of Priority 2 in the C Controller module.
Since a system error/stop (e.g. a system watchdog timer error) may occur in the C
Controller module depending on the entered command (example: command that
occupies CPU processing), special care must be taken to the entered command.
