Hi,

wenn I connect to an OPC UA Server from Siemens (S7-1500) I get a node with dataType ns=3;i=3063 (SimaticOperatingState). In UaExpert I can see by the value attribute that this must be an enumeration but I get only an integer.

Where can I get the enumeration value(s)?

Can anyone help me?

Markus

Yes, the enumeration values are transferred as integers. You will have to look for the respective enumeration values from the DataType node. Look for the respective EnumStrings or EnumValues properties.

See https://reference.opcfoundation.org/v104/Core/docs/Part3/5.8.2/ for more about those.
