Hello!

I was testing the Graph in TIA Portal V15.

The PLC side its all OK, now I was creating the GraphOverview component to show the status on the HMI.

The point is when I go to general, to select the TAG to connect the GraphOverview to its instance im not able.

The point is I should connect it to the ".RTDATA"or the whole DB instance?

On the component Link it seems to be OK, but on the TagList, the new tag created is on error.

Hello!

I´ve tried to connect to the tag you mentioned, at the component seems Ok, but when compiling the tag created on the list reports an error since It is not accessible at runtime. I tried to change its attributes but its "grayed out" and I couldnt change.

We are using TIA Portal V15 with and 1515F CPU and TP1200 Confort.

Any other hints??

Solved!

Here is the trick that I found in a post of Code Viewer!

The S7 GRAPH block has, as default, their signals not set to be visible / accessible from HMI / WinCC. So, to make possible toS7 GRAPH overviewworks properly, it is necessary to change this setting. It is made open the S7 GRAPH block, open menu -> Edit -> and setting the attribute “Internal parameters visible/accessible from HMI

Thank you, it was very helfull. I'm working with Tia portal V18, it was not easy find this property to make tags visible and accessible .Siemens could make an update and inclued this parameter in the normal properties. Like this is now, its a very specific and hard way to find this propertie.
