Hi
In the CallResponse of the method ResetJobCounters (see Euromap 83) the Porosys server returns an ArraySize of -1 for the StringTable in the ResponseHeader and the DiagnosticInfo.
The client from Beckhoff does not accept this. Now the question is, whether an ArraySize of -1 is legal (compliant to opc ua standard).
Can you please answer this question?
Best regards,
Manfred

“If an Array is null, then its length is encoded as −1. See 5.1.9 for a discussion of zero-length vs null arrays.”
