specifies the number of attempts to be made to re-establish communication. If
communication cannot be recovered within this number of attempts, the follow-
ing happens depending on the setting made for the Comm. Auto-return memory
switch (page 141).
•
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
communication are repeated until normal communication is 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 be-
fore is redisplayed and attempts are made to re-establish communication.
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 communication errors, refer to 7-2-5 Communication Errors and
Their Remedies (page 181).
Set the retry count with the third Memory Switch Setting Screen (3/4) as shown
below. (Refer to 6-9-12 Memory Switch Setting Screens for details on displaying
the Screen.)
Set a number of times in the input field to the
right of Retry Counts.
Each of the digits can be incremented or
decremented by pressing the asso
and – keys.
To set other memory switches, select the relevant screen using the [ ] (next
screen) or [ ] (previous screen) touch switch, then make the setting.
•
To confirm the settings and quit the memory switch setting screen, press the
Quit touch switch. The settings made last will be set and the NT21 will return to
the MAINTENANCE MODE MENU screen.
•
To quit the memory switch setting screen without confirming the settings, press
the Abort touch switch. The NT21 will return to the MAINTENANCE MODE
MENU screen with the previous settings still in effect.
