Abstract
The invention relates to a method for process control, wherein at least one process device to be controlled is controlled by at least one process module and by at least one safety module, in that process signals not relevant to safety are transmitted to a local control unit associated with the process device by the process module and safety signals relating to the process safety are transmitted by the safety module, wherein the process signals and the safety signals are logically linked to one another in the control unit and the result of the logical link is made available at a control output of the control unit to which the process device to be controlled is connected. The invention moreover relates to a system for process control, in particular for the carrying out of the method in accordance with the invention.
