Opc server request limitation
It seems reasonable for an Opc client to ask the opc server for Request settings (e.g. Operation Timeout, MaxOperationPerRequest). Is it mandatory for a server to publish these properties? If yes, where in the namespace is it found? And where is it found in the OPC UA standard?

Re: Opc server request limitation
Hello,
if a server has operational limits it should provide such information in it's information model.
Root->Objects->Server->ServerCapabilities->OperationalLimits
If a server does not provide such nodes, the client may assume that the server has "no limits".
However, a client must be capable of handling errors on all service calls and on all operations and react properly.
