Hi,
How can I write a single value of an array containing float values with writeValue() or writeAttribute()?
Thanks

Unfortunately, that’s not currently possible, but you need to use write like this
final WriteValue[] writeValues = { new WriteValue(nodeId, Attributes.Value,
indexRange.toString(), new DataValue(new Variant(value))) };
final WriteResponse response = client.write(writeValues);
final StatusCode result = response.getResults()[0];
We will need to introduce a new overload for writeValue() to enable specifying the range as well.

Sorry, but I always get StatusCode: Bad_IndexRangeInvalid (0x80360000) “The syntax of the index range parameter is invalid.”
I tested it with SampleConsoleServer / Client, trying to write a value of the “Int16Array” in “StaticArrayVariables”.
Thanks

How do you specify the range? We have been updating the NumericRange class recently, so you can also contact our support to test with the latest version (I also added new overload methods as mentioned to the SDK 2.0 beta already).

I tested it with your code snippet. Also tried it with different directly set String parameters in WriteValue(): “1:-1” (which equals NumericRange(1) ) , “1:1”, etc.
What is the correct syntax? SDK version is 1.9.1.

The correct string format is “1”

This way it works. “value” has to be formatted as array element…
Thanks!

Hi,
is it possible in this way to write single element of for example 2-dimesional array of simple type. I can’t figure out how to do that with NumericRange.
Or it is simplier to get the array, change the desired element of it and write the array back?
BR,
Goran

Yes, it is possible, if the server also supports that. You will need the new SDK 1.5 (or 2.0 beta) for that, though. NumericRange was extended to support multiple dimensions just recently.
