SL-F (SmartLine Field) is a component of Honeywell’s industrial control system architecture. It is an industrial communication system that allows for remote control, monitoring, and diagnostics of field devices such as sensors, valves, and drives. SL-F also provides an integrated hardware/software platform for process control, safety and logic applications in hazardous and non hazardous applications. It provides secure connection and communication from the central control system to the field devices and provides enhanced reliability, scalability, and cost savings through integrated industrial security and power management functions.
