Hello,

I'm using TIA WinCC Advanced V14 SP1 Update 7 and a TP700 comfort panel.

I would like to use a recipe to store settings for valves, ....  In the program every valve has its own instance DB with the same structure (Valve1=DB321, Valve2=DB323, ...)

I created a recipe for a valve with 4 elements and a recipe screen to copy the recipe to PLC. (see attachement)

If I use fixed recipe_DB  for element tags, its works fine but then I still need to copy the values from the recipe DB to the instance DB of the valve.

Wish: So I would like to send the recipe immediately to the correct DB of the valve. For the element tags I replaced the fixed DB Nr wtih the tag "Indirect_DB_Nr" (Int).  (see picture) So normally when I now send the repice to the plc, I would think that it is send to the DB that is set in tag 'Indirect_DB_Nr' (vb 321)

Problem: When I compile I have no errors or warnings but when I download the recipe to the plc I recieve 'PLC adress errors ' on the element tags and nothing arrives in the PLC. Somehow the DB Nr is not recognized.   Now when I use  the same principle with 2 IO-fields where in IO-field 1 I give the DB Nr and IO-field 2 displays a value of the given DB Nr,  this works.

Can someone tell me what I am doing wrong or is this way just not possible with recipes?

Perhaps with script?

Thanks for the help.

Hello Tombo,

where and when do you write the DB number to the HMI-tag Indirect_DB_No, on the PLC or o n the HMI? Does the HMI-tag Indirect_DB_No contain a value <> 0?

Hello Frink,

In the end I would like to use the DataRecordNr of the recipe as tag to assign the DB nr.

Every datarecord wil then get the correct DB nr as DatarecordNr. 

But for testing I created the tag 'Indirect_DB_No' (internal tag) a write the tag in the hmi right before the "SetDataRecordToPLC" function. (In case of picture fixed 325). So value <> 0.

I also tried to use an external tag in stead of internal but that makes no difference.

regards,

Tom
