6-9-13 Setting the Retry Count
The NT631/NT631C does not immediately display an error screen when a
communications error occurs, but tries to re-establish communications. The
Retry Counts setting specifies the number of attempts to be made to re-estab-
lish communications. If communications cannot be recovered within this num-
ber of attempts, the following happens depending on the setting made for the
Comm. Auto-return memory switch (page 179).
Comm. Auto-return ON:
Operation in the RUN mode is continued without displaying an error screen.
Regardless of the setting made for Retry Counts, attempts to re-establish
communications are repeated until normal communications are achieved.
Comm. Auto-return OFF:
The RUN mode is ended and an error screen is displayed. On pressing the
OK touch switch on the error screen, the screen displayed immediately before
is redisplayed and attempts are made to re-establish communications.
The System Menu can be displayed from the error screen by pressing any two
of the four corners of the touch panel simultaneously.
The setting range is 0 to 255 times. The default (factory) setting is 5 times.
Reference: For details on communications errors, refer to 7-2-5 Communications Errors
and Their Remedies (page 233).
