Continuous Operation
Leaving Internet Explorer open for extended periods with the system controller connected
may cause PC operation to become unstable. To avoid this;
• Shut down Internet Explorer once every day or so when running the system controller

CBM shuts and opens again automatically at midnight (4 a.m - 5 a.m).
• Avoid leaving three or more Web application windows opened for extended periods.
Usually, limit use to one "Group Monitor" application and one "Analysis Execution"
application.

message may appear.

(2) Click the button to continue using it. The Web application exits when the
button is clicked.
The [Analysis Execution] application recognizes that the user is still logging in for

minutes have passed since communication was terminated, the application logs

not possible within five minutes after the communication was terminated.
Shortcut keys
Don't press the shortcut keys such as the F5 (Refresh) key, the F11 (Full-screen) key.
