Unlike the C API, the DAQmx gRPC API only supports generic functions for getting and setting attributes. You can see a sample of getting an attribute in this Python example that uses GetTaskAttributeUInt32(), and a sample of setting an attribute in this Python example that uses SetTimingAttributeString().

The DAQmx gRPC API only allows accessing attributes defined in the proto file for the given category and datatype. This behavior can be overridden by adding "feature_toggles": { "nidaqmx.allow_undefined_attributes": true } to the server configuration file. This can be used to access attributes added in a later version. CAUTION: when allow_undefined_attributes is enabled, the client can request attributes for the incorrect datatype. The implementation of this is undefined behavior in the server's C API implementation. Only use this toggle when you can ensure that clients only access attributes by the correct datatype.
