For real work, this is probably not really a usecase. Nevertheless, this will happen quickly if somebody wants to test the dataserver. Then the most simple test is to start two plcs locally and thus we have exactly this situation. To allow this usecase without causing severe compatibilty problems, we simply return the other plc and go on. This flag is only relevant for scanning for a specific node. When searching all nodes, this flag will be ignored. It is up to the caller to do the according filtering. SearchForFirstMatch 16#10000 SearchForNonAmbiguousMatch 16#20000
