Hi Folks, Usually, To build a faceplate with Step7 v5.x and Wincc v7.x, i was used to declare in the DB, all needed variables with the property {s7 mc=true}. With this solution, i was able to bring Input, output or static varibles from my DB into the WinCC's structure, and i was able as well, to set on single input from my faceplate, if this one wasn't connected in the logic. For instance, in a motor FB, the input Auto/Man, it can be setted or resetted from the Faceplate it is not connected in the logic. But the above procedure is not possible to actuate in the Tia Portal. In these days i'm facing this problem with Tia portal, because the {s7 mc=true} property is not supported. So what i did, it's been create a "PLC Data Type" to be called in the DB and WinCC as well. But the problem is that in this way, the structure doesn't appear as an input, but with the struct's name only, and if i would set an external value at any variables of the struct, i have to do it, with a load/transfer instruction. As you can see is a little bit different from the WinCC v7.x Does anyone already faced this problem? How did you solve it? Thanks to anyone. Duccio. AttachmentStrcut.pdf (61 Downloads) |
