Starting the Operation
After completing the screen data transmission and setting the communica-
tions conditions, connect the NT20 to the Host and start operation.
Switching to RUN Mode
Press the Quit touch switch in the System Menu. The start-up screen in the
RUN mode will be displayed.
If the NT20 has failed to start correctly; e.g., the start-up screen is not dis-
played, an error message is displayed, or the screen is not displayed at all,
refer to
7-2 Responding to Displayed Error Messages
and take appropriate
action.
Note
When using Host Link, NT Link, or C200H Direct communications, the screen
displayed on startup is the one specified in the screen switch setting of the PT
status control area.
When using an NT20-ST128, the startup screen is specified with the Support
Tool when creating the screen data. If no startup screen is specified, screen
No.1 becomes the startup screen. If no screen data is registered for the star-
tup screen, the error message “Screen not registered” is displayed. For details
on screen numbers, see
4-3 Screen Display
on page 140.
Confirming the Communications between the NT20 and the PLC/Host
When using the NT20-ST128, use the RS-232C communications check func-
tion in Maintenance Mode to confirm normal communications between the
NT20 and the host. Refer to
Checking the Communications with the Host
(NT20-ST128)
on page 117.
When using the NT20, run the Host program and check that the following
operations are executed normally.
• Confirm that the NT20 screens switch according to the Host program exe-
cution.
If the screens do not switch correctly, check the connection between the
NT20 and the Host and also check the settings.
Refer to
SECTION 2 Hardware Settings and Connections
.
• Confirm that the information selected by the NT20 touch switches has
been correctly sent to the PLC by displaying the information of bits and
words by using a Programming Device (e.g., CX-Programmer). If the
information sent from the NT20 has not been correctly received by the
PLC, check the screen data settings (specifically the switch settings).
For details on the screen data creation, refer to the
NT Support Tool for
Windows Operation Manual
(Cat. No. V061).
