3. In Network 1, modify the "ON_OFF_Switch" tag to "1".

The "ON_OFF_Switch" tag is set to the signal state "1". The current flows through the

normally open contact to the coils at the end of the network. The "ON" tag is set and the

example machine thereby switched on. The OFF tag remains reset to "0" and has no

further effect.

4. In Network 2, modify the "LS_1" tag to "1".

The "LS_1" tag is set to the signal state "1". This simulates that a bottle is detected by the

light barrier "LS1" at the start of the conveyor. The "chamber_ON_OFF" tag has the signal

state "0", because the heating chamber is switched off during the simulation.
