Abstract
A safety device for a stored-program control includes a controller which exchanges data with a stored-program control and, via a bus controller and a bus system, with the peripheral to be controlled. A memory is provided, in which safety-relevant data of the stored-program control is stored, which is accessible to the controller.
Claims11
A safety device for a stored-program control coupling a computer bus system with a peripheral bus system, a peripheral being connected to the peripheral bus system, comprising:
- a controller for exchanging data with the stored-program control, the stored-program control continually executing an SPS program on a real-time operating system, the stored-program control exchanging data, via the peripheral bus system, with a peripheral to be controlled;
- and
- a memory for storing safety-relevant data of the stored-program control, the safety-relevant data being accessible by the controller.
A safety device for a stored-program control coupling a computer bus system with a peripheral bus system, a peripheral being connected to the peripheral bus system, comprising:
- a central controller for exchanging data with the stored-program control, the stored-program control continually executing an SPS program on a real-time operating system, the stored-program control exchanging data, via the peripheral bus system, with a peripheral to be controlled;
- and
- a monitor for monitoring a wake-Up signal generated by the stored-program control and transmitted to the monitor by the central controller, wherein the monitor activates, as a function of the wake-up signal, a bus controller, which controls a data transport via the peripheral bus system.
