System 800xA Control 6.0 AC 800M Configuration,
3BSE035980*
This section lists the warnings mentioned in the System 800xA Control 6.0 AC
800M Configuration manual.
Warnings
Entities and Reservation (Multi-User Engineering)
Reservations do not protect any runtime data or prevent download of modified
applications to a controller. For example, if a controller is reserved by user A, and an
application is reserved by user B, it is still possible for user C to download the
application. However, reservations are indicated in the Download dialog. A single
user who has logged on to more than one client, and several users who use the same
user account, can unintentionally overwrite configuration data.
Task Connections
Do not re-connect tasks to applications unless it is necessary, as this might disrupt
the task execution during reconfiguration. Else change the parameters of the
connected task (to fit the needs). A SIL3 task reconnection might lead to a shutdown
of the controller.
