A method for operating a control system for controlling a lighting system, the control system comprising at least two lighting control modules, each lighting control module comprising at least one digital processor and at least one digital memory for generating, managing and storing lighting programs, and each lighting control module comprising a housing in which the digital processor and the digital memory are disposed, and digital adjusting commands being generated in each lighting control module, said digital adjusting commands being transmittable to the lighting devices of the lighting system via data links, and the different lighting control modules being able to exchange transfer data with each other via data lines and data interfaces wherein

• a) a system time signal is generated in a lighting control module,
• b) the system time signal is transmitted to all lighting control modules of the control system via the data lines,
• c) the lighting programs in the different lighting control modules are executed using the system time signal.
