The case is: An inlet and outlet valve, a mixer motor, and digital level sensors to detect whether the tank is full or empty.

To do: Write PLC program on the same system using four different PLC languages. The required programming languages for the project are:

Ladder Diagram $($LD$)$

Function Block Diagram $($FBD$)$

Structured Text $($ST$)$

Sequential Function Chart $($SFC$)$

Programs should be written using an offline simulator$-$supported program $($e$.$g$.,$ OpenPLC Editor$).$ In the project report, the following should be included for each language:

Program

Simulation graphs of the inputs$/$outputs of the program over time.
