OPC Read Multiple

warning

OPC Read Multiple is only available for OPC UA connection.

The OPC Read Multiple reads data points recursively. Which data points should or should not be read can be configured using filters.

The following properties can be configured:

OPC connection	OPC connection used to access the OPC item group.
OPC address	OPC data point group whose values are to be read. Use the “...” button to open the tag browser (see below) to select an item interactively. For OPC UA connections, the node ID is managed in the background.
Refresh items	If active, the data points are re-browsed at this interval.

You can find out how the include and exclude filters work here:
