Defining OPC tag for OPC server

[hakan]

Hi;
In our project We have to define OPC tags for WinCC OA opc server. But There are a lot of tags and It will be take a lot of time individually defining in DP Groups panels. Is there any solution for example is it possible import from file included necessary tags.

Thank you
Best Regards,

Hello,

you could use wildcards at the configuration of the DP-group to include the datapoint-elements which has to be available at the OPC-server. Another possibility would be the configuration of the DP-group with a dpSet() from a script where you read the list of OPC-tags from an external source/an file.

Hello,

to define the dp-group-settings you have to set two elements of the _DpGroup-datapoint which is defined as the dp-group used by the OPC-server.

_DpGroup_Public.Types - a dp-type-filter can be defined (if necessary), if no filter is necessary an empty string has to be defined
_DpGroup_Public.Dps - dp-filter or a list of datapoint-elements can be defined

Please notice that both arrays need to have the same number of items for the correct functionality.
