Jeebs Posts: 218 Rating: (28)	Hi, Quick question: We have standard FB (like almost everyone else these days :D). But we have found that for some of these, we'd like to add the S7_m_c attribute to some IN paramters. This for the auto creation of tags on intergrated-WinCC compile. Added the attributes, made call of block, create new instance DB, then compile WinCC project. After compile, no new tags were created. Checking the other blocks, I noticed NON of them had IN parameters with the attributes. When the attribute is used the parameters are either INOUT or OUT. My question now is: For the S7_m_c attribute to actually create the tag in WinCC, do I need to configure the parameter as INOUT/OUT? Or should it work on IN parameters? Or did I miss something completely? Thnx Jeebs

I also need to configure my alarms in Step7 and see them in WinCC7.0. It looks a good information, even if I still can't see them displayed in my alarm table when they are true... Regards. David.

Assign in the IN parameter S7_m_c and make it true. In the FB properties also give the same. In the instance DB of the particular FB go to Special object properties and select WinCC attributes. Then Compile your OS. You will get the tag generated in your Win CC. Kindly go through the pictures attached with this. Hope this will help you. Attachment WinCC.zip (463 Downloads)

When I compile it for WinCC, nothing appears in WinCC. Contrary with bits in the Symbol Table where I can Display R O M C CC Columns and tick some. Then I can generate SDB. To sum up:This method (s7_m_c) works well with Symbol Table but does it work with bits inside DBs ? Thank you in advance. Regards. David.

I also set the attributes of the desired bits inside the DB, with the value "s7_m_c". With this method,I've got these desired tags in WinCC7.0 (tag loggin), but contrary to the "Symbol Tables", I can't tick something like "M" to get the tag in the "Alarm Loggin". Maybe only the "Symbol Table" offers this possibility (it displays the tick boxes: "O", "M", "C", "CC") ? Thank you all. David.
