6-2 Starting the NT31/NT31C
After checking that the hardware has been connected correctly, switch on the pow-
er 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.
[Initial Processing]
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 166).
[Memory Unit Check and Processing]
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 46).
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 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.
[Start of Communication with the Host]
Communication with the host starts in accordance with the communication meth-
od set in the system memory of the NT31/NT31C. During the interval until commu-
nication is established, the “system initialization screen” (screen No. 9000) is dis-
played.
For details, refer to “6-8 Starting Operation” (page 187).
If the “system initialization screen” remains on, display the System Menu by press-
ing two of the four corners of the touch panel simultaneously, and check the set-
tings for the communication conditions for communication with the host.
[Operation Start]
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 op-
eration by displaying the System Menu. For details on displaying the System
Menu, refer to 6-3-3 “Operations with the System Menu” (page 155).
