The invention relates to an improved method in an industrial safety system for controlling a process or equipment, which industrial safety system which includes components with safety devices. The safety system enables signals to be generated as a result of an event or alarm, where the method comprises creating an automated link between the event or alarm and an effect or an action to be taken upon receipt of said event or alarm signal due to the event. The method includes configuring one or more links between the event and the input, thus forming a cause and effect matrix (CEM), and also generating a control code using said cause and effect matrix (1) for subsequent download of said control code to at least one process controller (4-6, 31-33) whereby a control signal is subsequently generated by at least one safety controller to initiate the action or effect. The method in particular includes calculating a controller load for a safety controller (4-6, 31-33) processing said control code based on said cause and effect matrix (1) for said at least one safety controller such that the calculated processing load is not exceeded in any safety controller. |
