6-9-13 Setting the Retry Count

The NT31/NT31C does not immediately display an error screen when a commu- nication error occurs, but tries to re-establish communication. The Retry Counts setting specifies the number of attempts to be made to re-establish communica- tion. If communication cannot be recovered within this number of attempts, the following happens depending on the setting made for the Comm. Auto-return memory switch (page 183).

•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 239).
