6-9-11 Setting the Automatic Reset Function
The NT631/NT631C has a function for ignoring communications errors and
automatically returning to the RUN mode when they occur.
The Comm. Auto-return setting determines whether the automatic reset func-
tion is effective or not.
• ON:
When a communications error occurs, the NT631/NT631C automatically
returns to the RUN mode without displaying an error screen (the System
Initializing screen may be displayed).
• OFF:
When a communications error occurs, an error screen is displayed and
operation stops. Pressing OK on the error screen returns the NT631/
NT631C to the RUN mode.
The default (factory) setting is OFF.
Reference: • If a communications error occurs when OFF is set for Comm. Auto-return,
the NT631/NT631C makes the number of attempts at communications
with the host specified by the setting for the Retry Counts touch switch
(page 182). If communications cannot be re-established in any of these
attempts, an error screen is displayed.
• For details on communications errors, refer to 7-2-5 Communications
Errors and Their Remedies (page 233).
