NOTICE
Operator errors on the machine or plant
Data is synchronized if a hard disk fails. Depending on the work load of the processor and
hard disks, the system may react with some delay. Execution of keyboard, mouse or touch
screen commands may be briefly delayed in extreme situations. This could result in
operator errors on the machine or plant.
Do not operate safety-critical functions when a hard disk has failed.
