14 – Graphics

Conversion

Using the

hierarchy

There are two types of graphics that you may be migrating. Those

that originate in Tistar and those that originate in PCS OSx. Tistar

graphics are made from VGA line drawings. PCS OSx are based on

Kinesix’s Sammi HMI. Both of these have distinctly different

internal formats from PCS 7 graphics which are based on a format

used by WinCC. Both OSx and WinCC graphics have similar

functionality.

Converting Tistar graphics to WinCC is not possible. These must

be recreated using the WinCC Graphics Designer. Converting PCS

OSx graphics

is possible. PAS R&D provides a Graphics

Conversion service that converts a PCS OSx graphic to its static

equivalent in WinCC. It is as if a digital photo of the graphic was

made. However, this is not just an image. The objects in the

converted graphic are modifiable/movable lines and polygons.

Once you receive the converted graphics, you then have to add the

animations using the Graphics Designer.

Because DBA creates a hierarchy for you, you can use that to your

advantage to set up your graphics and their navigation. When you

compile a DBA project a blank graphic containing a symbol for

each of its objects is created for each DBA folder and placed in the

PCS 7 hierarchy. You can then replace each blank graphic with a

graphic of your choosing. Make sure you use a folder name or a

name for its associated graphic that matches the name of the

graphic with which you will replace it.

If you use PAS R&D’s Data Extraction service, included in the files

you get is a text file that is a cross reference of tags and graphics in

OSx. This file has a list of graphics and which tags each references,

and a list of tags along with which graphic that tag is on. This report

is also available in 4.1.2/4.1.2A OSx systems. You can use this

information to build your hierarchy in DBA. The limitation is that

DBA will not allow you to have the same tag in more than one

folder and consequently the associated graphic. You will have to

remedy that later in the Graphics Designer.
