Operation Start

Check if a Memory Unit is installed. If a Memory Unit is installed, processing (screen data and system program reading/writing) is executed in accordance with its DIP switch settings (page 39).

If there is an error in the screen data, an error screen is displayed. Pressing the OK touch switch on the error screen will return the display to that immedi- ately before the error occurred. It is also possible to display the System Menu from the error screen by pressing two of the four corners of the touch panel simultaneously. If there is an error in the system program, the main menu of the system installer mode is displayed. If this is the case, reinstall the proper system program.

Initialize the memory or change the settings as required.

Communications with the host start in accordance with the communications method set in the system memory of the NT631/NT631C. During the interval until communications are established, the system initialization screen (screen No. 9000) is displayed.

For details, refer to 6-8 Starting Operation.

If the system initialization screen remains on, display the System Menu by pressing two of the four corners of the touch panel simultaneously, and check the settings for the communications conditions for communications with the host.

The RUN mode is established, and operation starts in accordance with the screen data in the NT631/NT631C.

When changing the settings or checking the statuses, perform the appropriate operation by displaying the System Menu. For details on displaying the Sys- tem Menu, refer to 6-3-3 Operations with the System Menu (page 133).
