6-2 Starting the NT31/NT31C
After checking that the hardware has been connected correctly, switch on the
power to the NT31/NT31C to start it up.
This section describes the operation of the NT31/NT31C when it is started up.
6-2-1 Operation at Startup
The NT31/NT31C operates as follows when the power is switched ON, or when
it is reset.
Self diagnosis — including a check on the internal memory of the NT31/NT31C
and a system program check — and the internal processing required for startup,
are performed.
If an error occurs during initial processing, an error screen is displayed.
If there is an error in the system program, the system program must be re-
installed. For details on the installation procedure, refer to 6-5 Operations in the
System Installer Mode (page 150).
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 (pages 39 and 47).
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 immediately
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 simultaneous-
ly. If there is an error in the system program, the main menu of the system install-
er mode is displayed. If this is the case, reinstall the proper system program.
Initialize the memory or change the settings as required.
Communication with the host starts in accordance with the communication
method set in the system memory of the NT31/NT31C. During the interval until
communication is established, the system initialization screen (screen No.
9000) is displayed.
For details, refer to 6-8 Starting Operation (page 168).
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 communication conditions for communication with the host.
The RUN mode is established, and operation starts in accordance with the
screen data in the NT31/NT31C.
When changing the settings or checking the statuses, perform the appropriate
operation by displaying the System Menu. For details on displaying the System
Menu, refer to 6-3-3 Operations with the System Menu (page 138).
