Faceplates and

symbols

internal. For example, if you need non-networked text tags, you can

create a new tag structure TEXTN that is a duplicate of the

505_TEXT structure, except for the fact that all the tag elements are

designated as internal. If you need faceplates and symbols, you will

have to create these also. These can also be copied from those used

for the 505 structures. Then, for each non-networked OSx tag you

want in PCS 7, create an instance of that all-internal tag structure.

An additional factor to be considered is how the non-networked

tags are manipulated. Networked tags are modified by the PLC or

from a graphic. Since there is no PLC for a non-networked tag,

there is no implicit automated way to write to such tags. When you

design the PCS 7 system you need to provide logic to manipulate

the migrated non-networked tags. OSx can use reports or BCL

programs. In PCS 7 you can create scripts or actions that simulate

the logic used in OSx.

OSx has two faceplates for each tag type. A small faceplate and a

large faceplate. The small faceplate is used in tag group displays

and the large faceplates are used in tag detail displays. Symbols

also exist for each tag. You have the freedom to choose from a

variety of animations for these.

PCS 7 has a similar scheme, except it doesn’t have the small

faceplate. Faceplates and symbols are for PCS 7 tag structures.

Symbols exist on some graphic. When you add a tag to a folder in

DBA you are adding a tag symbol to the graphic that will be

associated with that folder when the DBA project is compiled to

WinCC. You can choose in DBA which symbol to use (if more

than one exists) but you cannot choose its animation. If there are

more symbols than can fit on a screen, then some symbols will be

below the bottom of the screen and will not be visible; the default

graphics that DBA creates are not scrollable. You will have to

manually add scroll bars via the PCS 7 Graphics Designer.

Each symbol opens the tag’s faceplate in a separate window when

clicked with the mouse. Unlike OSx, you can have two faceplates

for the same 505 tag structure displayed at the same time.
