allayahassine Posts: 133 Rating: (0)	Hello, In SIMATIC MANAGER, i have created in DB2 (global data) an Int variable called DB_VAR. Now, In WinCC flexible, i created a tag calledDB2.DB_VAR_1 and i want to set DB_VAR as a mnemonic for it, but the list of the available mnemonics is empty. Even if I try to write it (DB_VAR), it is not accepted. Help me. thanks))

IBN-Service Posts: 8946 Rating: (1000)	Use Symbol table to give a symbolic name for DB 2. Call it "Data" for example. DB2.DB_VAR_1 must be Data.DB_VAR_1

allayahassine Posts: 133 Rating: (0)	done and saved, but in the mnemonic field in WinCC flexi(ble, it is written, under the project name, <Update with PLC Data...>: it is an empty list, neither Symbol Table nor DB2 are accesible.

rg-link Posts: 19 Rating: (0)	Dear allayahassine, Try to re-integrate your WinCC Flex. object in Step7 project: 1) Make a backup ; 2) In WinCC Flex. run "File --> Copy from Step7" and save current HMI project (hereafter called as "COPY") at any place, except Step7 project directory. In COPY project, check used by tags connection(s) name(s); 3) In Step7 Manager, delete integrated HMI-object, which copy you've got at the previous step; 4) Open COPY in WinCC flex. and integrate it in Step7. Connect the HMI object in NetPro if necessary. This procedure also creates a new PLC-connection which isn't used by any tags. Only this one has the non-empty "Station" field. Delete this connection; 5) choose your PLC(s) in the "Station" field for connections. You'll receive the message, accept it. This method helped me several times. P.S. I guess "Reconnect" button (see attachment) may be useful but I hadn't a chance to try. Could you check it? Best regards Attachment Message_and_Reconnect.JPG (185 Downloads)
