The Knight-Tec Radar Sensor integrates directly into PLC systems using the robust Modbus RTU (Remote Terminal Unit) protocol over a serial transmission standard, such as RS-485. This provides several advantages for industrial environments:
Reliable Serial Communication: Modbus RTU is designed for deterministic, master-slave communication over two or four wires, making it stable in electrical noise-heavy warehouse or factory environments.
Simple Network Configuration: Sensors are addressed as slave nodes on a bus, allowing multiple units to be networked to a single PLC gateway or controller.
Access to Core Data: Modbus registers can be programmed into the PLC to retrieve critical real-time data, such as distance measurement, detection alerts, signal strength, and basic diagnostic codes.
Industry Compatibility: As a widely accepted open standard, a Modbus RTU connection ensures the Knight-Tec sensor is compatible with a vast array of existing PLC hardware and human-machine interfaces (HMIs) from various manufacturers.
