Explaining how Siemens S7 PLC Addressing Works & Programming Challenges

Hi All

I am trying to explain S7 programming to our apprentice in the office and I am having a few issues, I know what I mean but not sure if im explaining it well, In particular I am refereing to how the addressing works (inputs,outputs, Memory words bits etc )Any good advice ?

Also can you think of any good programming challenges I can set

( have done the traffic light one )

We have a small S7 300 test plc wired up with 16 inputs & 16 outputs

Many Thanks !!

John
