A safety-related control device for controlling an actuator with a first processing device that is configured to provide a safety function for the generation and/or processing of a signal for a safety-related control of the actuator, and a second processing device that is configured to provide an operating and/or additional function for the generation, processing, diagnostics, reproduction and/or transmission of further signals associated with the operation of the control device and/or of the actuator, and wherein the second processing device is furthermore configured to provide a test function for monitoring the functionality of the safety function.

The present invention makes it possible to reduce a load associated with transfer of parameters. A control system is equipped with first and second controllers connected to a network, and a drive apparatus for driving a motor in accordance with an instruction from the first controller. The drive apparatus includes a memory that stores a safety program for implementing a safety function, and a parameter group referenced by this program. The second controller transmits an instruction related to work of the safety function to the drive apparatus. A support apparatus capable of being connected to the network generates the parameter group, and reduces a size of the parameter group when this parameter group is transferred to the drive apparatus in order that the parameter group can be restored by the drive apparatus.

A static safety analysis for control-flow linearization receives a control flow graph (CFG) and an intermediate representation of a computer program, and identifies, for a given loop, all memory load instructions belonging to one side of a diamond-shape structure in the CFG. For each representation of an address of each memory load instruction identified, determining whether it is used on all other sides of the diamond-shape structure. Responsive to determining each representation of an address of each memory load instruction on the one side of the diamond-shape structure is used on all other sides of the diamond-shape structure, determining whether an immediate predecessor of a top of the diamond-shape structure for the given loop post-dominates a header of the given loop. Responsive to determining the immediate predecessor of the top of the diamond-shape structure for the given loop post-dominates the header of the given loop, affirming safety of linearization.

Modern large buildings and public places are equipped with a plurality of elevators, exits and points of interest for fluent movement. The passenger flows in a building or public place can be traced and modelled by using statistics and information regarding current state of the modelled building or public place. The information derived from this model can be used for controlling elevators, escalators and similar in the building more efficiently. The same information may be used also for guiding passengers in the building or public place to use other transportation means so that the duration high traffic situation can be reduced or sometimes completely avoided.
