This paper presents the experience of using a CORBA-based communication package for inter-component communication of control and status information in the ATLAS prototype DAQ project. A public domain package, called Inter-Language Unification (ILU) has been used to implement CORBA-based communication between DAQ components in a local area network (LAN) of heterogeneous computers. The selection of the CORBA standard and the ILU implementation are judged against the requirements of the DAQ system. An overview of ILU is included. Several components of the DAQ system have been designed and implemented using CORBA/ILU for which the development procedure and environment are described
