An automation system for monitoring a safety-critical process includes a platform configured to execute user programs that implement a safety function, a fail-safe peripheral module configured to couple the user programs with the safety-critical process, and a monitoring device configured to ensure fail-safe execution of the safety function on the platform. The monitoring device is couplable to the platform via a first communication interface and the fail-safe peripheral module is couplable to the platform via a second communication interface. The monitoring device runs a fail-safe service independently of the platform, via which the monitoring device interacts with the fail-safe peripheral module. The fail-safe peripheral module signals a safe state based on the implemented safety function and the fail-safe service.
An automation system for monitoring a safety-critical process, comprising:
A monitoring device for ensuring fail-safe execution of a safety function implemented by user programs on a platform, wherein the monitoring device is couplable to the platform via a first communication interface and configured to run a fail-safe service independently of the platform, via which the monitoring device interacts with a fail-safe peripheral module, so that the fail-safe peripheral module signals a safe state based on the implemented safety function and the fail-safe service.
A fail-safe peripheral module for coupling a safety-critical process to a platform, the platform executing user programs in order to implement a safety function, wherein the fail-safe peripheral module is configured to interact with a fail-safe service, which is implemented on a monitoring device that is couplable to the platform and implemented independently thereof, and wherein the fail-safe peripheral module is configured to signal a safe state based on the implemented safety function and the fail-safe service.
A method for monitoring a safety-critical process with an automation system, comprising:
