Indicator lamps in a control system are primarily used to convey which type of information?

• A. Status of machine states
• B. Wireless connectivity status
• C. Data storage level
• D. Network bandwidth

Answer: (A)

Indicator lamps provide visual feedback of the current state of a machine or process. They instantly tell the operator what the equipment is doing or what condition it’s in—for example, running, idle, or faulted—often using color coding to convey meaning quickly. This at-a-glance status information supports safe operation and rapid decision-making. They aren’t designed to show wireless connectivity, data storage levels, or network bandwidth, which require other instruments or displays. The focus on immediate status makes lamps the straightforward way to communicate how the system is behaving at a glance.
