Structure Segments in the P&I Diagram

You can visualize the structures in the P&I diagram by placing structure segments as structure boxes. You then see immediately which apparatuses and machines drawn in the P&I diagram belong to which structures.

To this purpose you drag & drop a structure segment from the pre-planning navigator onto a P&I diagram. In the process a reference is generated to the structure segment and this reference is placed as a structure box on the P&I diagram. The structure identifiers of the structure segment are transferred to the structure box. The associated structure box is displayed in the pre-planning navigator below the referenced structure segment (icon ).

The following is possible:

The properties of the referenced structure segment (and of any superior structure segments) can be displayed at the structure box on the P&I diagram page. To this purpose the source objects "Segment" and "Structure segment hierarchical" are available in the dialog Property selection.
A structure segment can be placed several times in the P&I diagram. Depending on the layout of the apparatuses and machines drawn in the P&I diagram that belong to the same structure you can either draw a structure box around all the objects or several structure boxes with the same DT around the individual objects. As usual a structure box can also be drawn as a polygon in the process.
You can jump from the structure box displayed in the pre-planning navigator to its placement on the P&I diagram page via the popup menu Go to (graphic).
Modified structure identifiers at the structure segments in the pre-planning navigator can also be transferred to the placed structure boxes via the popup menu item Update detailed planning . To this purpose you activate the check box Update device tags and symbolic addresses in the subsequent dialog.

Displaying the visible designation at PCT loops

The property Designation (visible) (ID 44065) allows you to have a "reduced" designation displayed at the PCT loops / PCT loop functions which are placed in a structure box. In this property the designation of the superior structure box is abbreviated, meaning that the partial structure in which the PCT loop / PCT loop function is located is displayed.

If a PCT loop / PCT loop function belongs to a different structure, a "reduced" designation is displayed. In this case a ">" is displayed before the designation.

The Designation (full) (ID 44009) property shows the complete designation of the PCT loop / PCT loop function including the structure identifiers of all the higher-level segments.
