Reset the EJ1 to enable the setting.
Setting range
0: Continue Programless communications will be restarted automatically
when the cause of the programless link error has been removed
and communications are possible with the PLC.
1: Stop Read/write operations for PLC memory will not be performed
even after the cause of the programless link error has been
removed and communications are possible with the PLC.
Instead, EEEE will be set in the Operation Command Response
Bits. Refer to Method for Canceling Communications Errors on
page 154 for information on clearing the error.
When using the default Basic Unit settings, programless communications will
stop if a programless link error occurs. This will make reading parameters,
changing settings, and executing operation commands impossible. When
starting normal operation, it is recommended that the programless communi-
cations error operation selection be set to continue operation.
The settings are the same as made when checking operation. Refer to Check-
ing Operation with SYSMAC CS/CJ Series PLCs on page 117.
The settings are the same as made when checking operation. Make settings
based on the following table if the baud rate or transmission settings need to
be changed.
