This tool has to be selected if you want to place standard Boolean logic blocks on the programming interface. The specific type of block is selected from this group from an additional toolbar that is opened when you select the basic functions tool.

AND AND with edge evaluation NAND NAND with edge evaluation

OR NOR XOR NOT

Inverting the inputs

You can invert individual inputs:

• A logical "1" at a specific input is inverted to logical "0" in the circuit program.

• A logical "0" is inverted to logical "1" in the circuit program.

To do so, right-click on the input and select the invert command from the shortcut menu.

You cannot invert the inputs of output blocks.

0BA0-0BA3: To invert an input, use the basic function NOT.

Timing diagrams

Each timing diagram of the basic functions displays three inputs to make evaluation easier for you.

0BA0-0BA3: The basic functions have three inputs.
