The safety system plays a decisive role in the modern process control systems thanks to the broad usability of guidelines and standards which became uniform and compulsory in most countries.
Through an example of a manufacturing cell of the car industry, I present in this thesis the steps leading to the reliable programming of a safety system and which rules are in effect for its overall lifetime.
First I analyzed the standards regarding the safety and their method of use, dealing with the standard IEC 13849 in details. With the help of the latter I performed a simplified risk analysis and compared it to the engineering practice. Using the result of the risk analysis I planned the configuration of the safety function
After this I chose and calibrated the hardware elements of the safety sytem. I used the Siemens Distributed Safety package to form the safety control because the program’s final structure and principle of its operation meet this way the requirements for sure.
Finally I specified a diagnostic solution for this particular system and looked for possibilities of optimization.
