After logging off, objects assigned password protection can no longer be operated; to do so,
log on again.
Further information on this may be available in your plant documentation.
Logoff time
A user logoff timeout can be set in the system. If the time between any two user actions, e.g,
entering a value or changing screens, exceeds this logoff time, the user is automatically
logged off. The user must then log on again to continue to operate objects assigned
password protection.
