The LEP control system will be constructed as a global communication system where microprocessors will be used everywhere, from the management of the communication mechanisms, the execution of complex control procedures, and the supervision of the equipment. To achieve this, the global control problem has been cut into sizeable functions which will be encapsulated into microprocessor modules containing enough hardware for the function to be mostly self-contained. This leads to a function architecture where messages are exchanged between the functions on miscellaneous media. It will be shown how these message exchanges can be organized into a uniform flow of data all through the system.
