AND (Bitwise AND) Ladder Logic Instruction

The Bitwise AND instruction is a ladder logic rung output instruction that performs an AND operation on Source A and Source B and places the result in the Destination tag. The instruction is enabled when the preceding logic is true and disabled otherwise. The values can be constants, tags or any combination.
