We are running a plant with Simatic and a 3rd party Scada.
All the process objects is numbered and is set up with Koppel-DBs to the Scada system with x bytes per object (for DBComm/DBStat/DBAlm and so on.). Works well on the Scada system.
Now we are about to install a TP1900 comfort panel to show motor/valve status signals and to have some simple command buttons, locally in a cabinet.
I have tried to use Graphic lists to show 8 different motor status signals on the TP, but this does not work because there are several bit set at the same time, and then the TP shows a salad field instead of my symbol. It works only in occations with one bit set.
Is there a hidden, secret way of prioritizing the bits in the Graphics list to show the right symbol, or do I really need to make a new DB with single bits (or value 0- 8 only for the TP?
