AND

 

AND with edge evaluation

 

NAND

 

NAND with edge evaluation

OR

 

NOR

 

XOR

 

NOT

Select the block that you need to place it on the programming interface.

Inverting the inputs

You can invert individual inputs:

To invert an input, right-click 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.
