This is effected in that, given a commissioning or a configuration modification, the assembly having the respectively most current program is identified, this program is communicated to the other assemblies and is incorporated into the function execution of the respective assembly. The updating ensues independently of whether assemblies that are already present or newly added assemblies contain the most current programs. ## Claims ### Claim 1 A method for updating a program structure of a modular communication system having computer-controlled assemblies connected via a common bus, one of the computer-controlled assemblies having defined as a main assembly and every computer-controlled assembly respectively having programmable program memories available thereto, comprising the steps of: generating a system image of the communication system on each assembly of the computer-controlled assemblies by an exchange of program-oriented and circuit-oriented messages between the assemblies of the computer-controlled assemblies under control of the main assembly and storing the system image in a system list;
