■ Function to Mask the Screen during Remote Access
This function ensures security during servicing work using remote connection.
The machine has an option called Remote Operation Viewer for remote control via a network. This option enables a service
technician to perform maintenance on the machine from a remote location.
However, the same screen is displayed on the Remote Operation Viewer screen and the Control Panel during the work, which
carries the following risks.
• The screen being operated can be seen by the user.
• During remote operation, the user may perform an operation on the Control Panel and an unexpected processing may be
executed.
To solve these security problems, a function has been added to display a message on the Control Panel screen when the machine
is being operated remotely using Remote Operation Viewer in order to prevent the user from performing unexpected operations.
As shown in the figure below, the mask screen is displayed when this function is enabled.
