Logic Solver Not AND function block execution

The number of inputs to the LSNAND function block is an extensible parameter. The block default is two inputs.

To add input connectors to the block:
  1. Select the block diagram.
  2. Right-click and select Extensible Parameters.
  3. Modify the number of inputs.
  4. Click OK.
The LSNAND function block examines the inputs you define and applies the logical AND function to the inputs, then applies the logical NOT function. When all inputs are True (1), the output is False. When one or more of the inputs is False (0), the output is True.
