Abstract: Automation technology facilities are used for automating industrial processes such as the control of conveyor belts. A high-level control device with a logical model of the plant stored in the control device is disclosed. Simulation models and control programs are generated by the control device. The generated control programs have special data blocks which contain the parameters that are to be optimized by the simulation. The generated simulation models generate the parameters as result values of the simulation evaluation algorithms and supply the values in an automated manner to the special data blocks of the generated control programs.

Abstract: A method and a programmer for logical connection of a plurality safety circuits in an industrial automation arrangement, wherein a subordinate one of the safety circuits and a super-ordinate one of the safety circuits are each described in a safety matrix. An overall matrix is generated from the safety matrices of the subordinate and super-ordinate safety circuits and the overall matrix indicates the connection of the safety circuits and is automatically converted into a safety-related program.
