Check: Time Frame

Use

Optional check that is used to ensure that further switcheson a technical object are only executed if an operational condition/typeis confirmed as executed.

At the start of each operational phase, an activity, that is, a change in the operational condition/type, is announced. As long as you do not confirm the execution of this activity, it remains undefined in the system, even if it has already been executed.

Therefore, no further operations can be executed.

Features

At the start of the operational phase, the system logs the operational condition/type, which the technical object should obtain for each operational group. This entry is only deleted again when you confirm the new operational condition/type.

However, if another entry already exists using an intended operational condition/type, the technical object cannot be switched, unless the intended operational condition/type and the existing operational condition/type agree according to the criteria defined in the application profile.

Activities

You cannot skip the check. However, you can change or deactivate it.

Example Example

There are three Operational WCDs – WCD 1, WCD 2 and WCD 3. In each Operational WCD, the technical object ValveA should be switched as follows:

End of the example.

Operational WCD

Technical Object

Tagging Condition

WCD 1

Valve A

ON

WCD 2

Valve A

ON

WCD 3

Valve A

OFF

Note Note

This is a simplified example, in which both the same operational group and the same operational type are assumed.

You exit the tagging for Operational WCD1. This means that you set the status to BTG (Tag) . Before you confirm execution, Operational WCDs 2 and 3 should also be tagged. The check does not generate a message for the tagging of Operational WCD2, because the technical object ValveA is to be set to the same tagging condition as Operational WCD1. However, the tagging of Operational WCD3 is prevented, because the tagging condition is different from that already triggered.

End of the note.
