Scripting
Changing Values in OPC-UA
Hint:
If a shared OPC UA connection already exists, you can skip the next step and use the existing connection.
Changing values in an OPC-UA connection can be achieved via script. First, an OPC-UA data source must be created. The connection of this data source is then used to establish a connection with the OPC-UA server and change the values.
Changing Values
The following script demonstrates how to change values via an OPC-UA connection. It assumes that the data source has already been created.
In the block, first select the connection to be used for connecting to the OPC-UA server. Then, specify the NodeID of the value to be changed and the new value along with its data type.
The block can be found under Publish to external systems -> OPC-UA -> Set variable.
If the modification is to be done in script mode, the following script can be used:
connections.getfromid('oi4AHK7cVuFfTFvjf/okKZLrNBc=').writevalue('ns=2;s=TestData_TestBool', true)
