Figure 123: Example filling
Task 1 Vessels are to be filled.
1. if the lid and the material are present, the green lamp will light (OK)
2. if the vessel is at the wrong height or in the wrong position, the red lamp will
The presence of lids and material is indicated by sensors (for the time being
one sensor should be sufficient for the material, the example can be extended
later on to monitor minimum and maximum level).
Task 2 Modification of 2. (new project): In case of a fault a horn blows until it is reset.
To do so another input is required, the reset button.
Implementation The correct function of the programs can be tested using a simulator if the
hardware is present and ready for operation. It can also be tested without any
hardware in the simulation mode. A visualisation is a good choice. If more
inputs are needed than there are on the (small) simulator (e.g. maximum level
or reset button), you can work with a combination of physical inputs on the
simulator box and inputs in a "simulated" inputs visualisation.
