Restore dialog

After you click the Restore button on the Setup tab, the Restore dialog opens, where you can select one or more nodes to restore.

You can also specify the following options in the Restore dialog:

Pause or resume the execution of the restored nodes at restore time.
If you enable the Pause Nodes option, you must manually resume execution from the Setup tab by individually selecting each node, and then clicking the Resume Execution button.
Restore the saved operating parameters, tuning parameters, or both (for .XML option only).
Typically, only the operating parameters are restored when running a training scenario, because the current tuning parameter values are more appropriate than the saved values.
Initiate playback of operator changes following execution of the restored nodes by enabling the Playback After Restore option.
You control playback from the Setup tab, but must initiate it from the Restore dialog. At restore time, playback history begins by default from the date and time that the system state was saved; however, you can adjust the time window by using the Update button on the Setup tab.

Depending on what type of restore was selected (.XML or .DAT), for every selected workstation, Simulate copies the DeltaV\DVData\Simulate\NodeName\SIMmmddyyyyhhmmss.xml (or .DAT) and DeltaV\DVData\Simulate\NodeName\SIMmmddyyyyhhmmss.xmlcheck (or .check) files from the ProfessionalPLUS workstation to the DeltaV\DVData\Simulate folder on the selected workstations.

At save time, the database uses the following rules to set the default category for parameters in an .xml file:

Operating – Parameters with a functional category of Operating, IO, Misc, and (if not writeable) Alarm
Tuning – Parameters with a functional category of Tuning and (if writeable) Alarm
Always – Module level parameters

At restore time the parameter values in the .xml file are selectively restored based on whether you specified the Restore Operating Parameters option, the Restore Tuning Parameters option, or both in the Restore dialog. To customize restoring behavior, you can edit the Category string in the .xml file for a node. To restore a parameter regardless of any option that you specified in the Restore dialog, change the Category string to Always. To prevent a parameter from being restored, delete the Attribute element for its Category string from the .xml file (or change the Category string to anything other than Operating, Tuning, or Always).
