HOOTING
(c) Operating Status Consistency Check Settings
1) In order that no error will be detected when the operating status is changed
during normal operation, uncheck "Check operating status consistency" at
backup mode settings in the redundant parameter settings.
Then, write the parameter to the CPU module, reset it, and the parameter
setting will take effect.
2) When "Check operating status consistency" is unchecked, the CPU module
will not detect an error even when writing the parameters with GX Developer to
change the CPU operating status.
3) When powering on both systems simultaneously, even if the backup mode
redundant parameters are set not to check the "Check operating status
consistency" has been unchecked at the backup mode settings of operation
mode settings in the redundant parameter settings, it will execute a
consistency check.
