Hello,
StatusCode Bad_NotWritable means that the user isn’t allowed to write the Value of the specified Node. The Server might allow another user to write the Value, but it could also not allow any users to write it.
Please, check the AccessLevel and UserAccessLevel Attributes of the Nodes. If they contain the CurrentWrite flag, then writing the Value of the Node is allowed. Otherwise, writing it is not allowed.

Hello Sabari,
You need to access the source code of your OPC UA server to modify these attributes of the node. Please refer to the sample code in SampleConsioleServer.java which is included in the SDK.

Hello,
As the name of the StatusCode suggests there has been a mismatch of data types. This StatusCode is returned by Write Service when attempting to Write a value with DataType that isn’t the same or a subtype of the target Attribute’s DataType. Verify that the value you’re attempting to write has a proper DataType. See https://reference.opcfoundation.org/Core/docs/Part4/5.10.4/ for more information on the Write Service.
