3.7 Writing and starting the circuit program
We do not need the last two inputs of the OR block for this circuit program. You can mark the
unused inputs with an 'x'. Enter the 'x' character twice:
1. Switch to editing mode: Press OK
2. Select the Co list: Press
3. Accept the Co list: Press OK
4. Select 'x': Press
5. Apply x: Press OK
Note
You can invert individual inputs of the basic and special functions; that is, if an input
carries a logical "1" signal, the circuit program will output a logical "0". On the other hand,
a logical "0" is inverted into a logical "1" signal.
To invert an input, move the cursor to the relevant position, e.g.:
Confirm with OK.
Now press
Next, press ESC.
You can review your first circuit program by pressing
