Reference Object and Object List
Use
You can enter a reference object in a
WCM object. This can be either a functional location or equipment. However, it is not possible to enter both.Prerequisites
The reference object must be included in the installation structure of the Plant Maintenance (PM) component.
Features
The location data are derived from the master record of the reference object in the WCM object.
You can use the optional
check "reference object" to check whether a technical object to be switched is already the reference object of an active lockout/tagout.You can enter further technical objects in a so-called object list. This is particularly advisable, if, for example, border armatures are defined for a lockout/tagout and are tagged. In this case the object list can contain the list of all tagged components (therefore, also those which are within the border armature).
If an object list exists for a reference object of a WCM object, then you cannot change the reference object in the WCM object.
