 ====== Simple System with Control and Safety System ======
-It is time to study a basic system consisting of a control system and a safety system. The control system encompasses a few blocks and one of their signals will be written to an output. As we do not have any real output we will use a simulator, see [[getting_started:install_wrapper#simulator|]]. Please build and install it. Further, you have to make sure that your example application is able to find the simulator library, see [[getting_started:deploy|]].\\

 This example encompasses a safety system and a control system. The control system has one time domain running several blocks

 Upon switching the block also triggers a safety event. The safety system has four safety levels.

 The system will start in level ''slInitializing''. The system will stay there for five seconds after which the time domain is started and a ''seStartRunning'' event is triggered. This will change the safety system into level ''slRunning''. Here, the integrator sums its input signal up to where the switch reaches its trigger level. The switch will automatically switch to its second input, which is simply a constant signal and the safety event ''seStopping'' causes the safety system to change into level ''slStopped''. It will stay there for three seconds after which it changes back into level ''slRunning'' and also switches its input back to its first input. After that the cycle restarts.
