. The context of this problem is the development of software controlling an industrial press, where sheets of metal are pressDevelop a fault-tree to identify possible failures that can lead to the operator (or someone else) being caught in the press.. The context of this problem is the development of software controlling an industrial press, where sheets of metal are pressed into different shapes. An operator is responsible for inserting removing the press cycle, which consists of the press moving all the way down, and then up again. and sheets. The operator also starts the Since the press is highly safety-critical, different steps are taken to increase the safety of the operator. To make it impossible (or at least much more difficult) for the operator to start the press when still holding the sheet, there is a protective cover that must be in place in order for the press to operate, and the start button is placed some distance away from the press. The requirements on the press incl following concerns ude the 1. The press should never move if the protective cover is not closed. 2. If the protective cover is opened during the press cycle (i.e., when the press is moving), the cycle should be aborted, i.e., when it is closed again the press should return up also if it did not yet reach the bottom position. The system has the following sensors and actuators Sensor Description PC O PC C P U P M P B SB The protective cover is The The press reachest The press reaches middle position The Start button ive cover becomes closed sition s reaches bottom position ed Actuator Description PM Possible values Up, Down, Stop Press motor Develop a fault-tree to identify possible failures that can lead to the operator (or someone else) being caught in the press. Would you recommend additional requirements based on this analysis? Please list these. Show transcribed image text .
