Based on the safety concept, safety experts from SICK create detailed specifications of the safety-related application software (SRASW) as well as the configurable and parameterizable safety components. This not only prevents programming errors and ensures safe and reliable application software, but also compliance with normative requirements. Based on the specifications, the safety controller is then programmed and interfaces to the machine process control are prepared. A final code review ensures that an error-free program is available for later commissioning of the machine.
