Logical

The following section describes the logical function blocks
found in the standard category.

Logical And (AND)

The Logical AND function block, shown in Figure 10.37, acts
exactly like a logical “and” gate. If both inputs are True, the
output is enabled. On the other hand, if even one of the inputs
are False, the output is disabled. All inputs and outputs of this
function block must be Boolean.

Inputs

A -- Boolean input element.

B -- Boolean input element.

Outputs

C -- Boolean output element.

Logical Or (OR)

The Logical OR function block, shown in Figure 10.38, acts
exactly like a logical “or” gate. If either or both of the inputs
are True, the output is enabled. On the other hand, if all of the
inputs are False, the output is disabled. All inputs and outputs
of this function block must be Boolean.
