Refer to the following parallel circuit containing two switches.

Switch S1 and switch S2 switch the load.The parallel circuit of S1 and S2 is anOR operation in LOGO!, becauseS1 or S2 switches on the output.

Switch S1 acts on input I1 and switch S2acts on input I2. The load is connected at

relay Q1.

You now enter the program (from theoutput to the input!). To start, LOGO!displays output Q1.

Below the Q of Q1, you see anunderscore (_). We refer to theunderscore as a cursor. The cursorindicates your current location in theprogram.

You have entered the first block. Each block thatyou enter has a block number (B01). Now all you

have to do is connect the inputs of the block

(B01).

Press the key.OK

Refer to our example below:

If switch S1 is closed, input I1 is energized and the state of input I1 = 1.

The LOGO! program determines the output states.

In this example, the state of output Q1 = 1.

If the state of Q1 = 1, LOGO! enables relay Q1 and the load at Q1 is energized.
