A control system adapted for real time applications for carrying out the following functions: communication, control of a process or a device, and safety functions. The control system includes a plurality of function modules adapted for at least carrying out the control function and the safety functions. Each function module is adapted for receiving input data and for providing output data. Each function module is adapted to carry out a defined task based on the received input data and provide output data based on the task carried out. Each function module is adapted to carry out the task during a time period, which is independent of what is simultaneously going on in the other modules. At least one of the function modules has its logical components implemented on a programmable logic device.
