Paraphrase the following: " Elements of Ladder Logic Let's explore the essential elements of ladder diagrams: Contacts (Input Symbols): Contacts represent input conditions (e.g., switches, sensors). Types of contacts: Normally Open (NO): Represents an open switch (logical 0). Normally Closed (NC): Represents a closed switch (logical 1). Coils (Output Symbols): Coils represent output devices (e.g., solenoids, motors). Types of coils: Output Coil: Activates an output when input conditions are met. Output Latch: Retains its state even after input conditions change. Rungs and Logic Flow: Each rung contains a combination of contacts and coils. Logic flows from left to right within a rung. Parallel contacts represent logical AND operations. Series contacts represent logical OR operations. Beverage Packaging Process Control Example Let's create a simplified ladder diagram for a beverage filling process: Objective: Control the filling process to ensure accurate liquid quantities in containers. Components: Input: Liquid level sensor (NO contact). Output: Filling valve (output coil). "
