The NT50-DP-RS is a specialized industrial protocol conversion gateway developed by Hilscher, a leading provider of industrial communication solutions. It is designed to establish bidirectional data communication between PROFIBUS DP networks and serial communication systems (RS-232/RS-485), serving as a critical "protocol translator" to integrate legacy serial-based devices (e.g., sensors, meters, actuators) into modern PROFIBUS DP automation architectures. This gateway is widely applied in industrial scenarios such as factory retrofits, process control systems (water treatment, HVAC), and machinery monitoring, where seamless data exchange between serial equipment and PROFIBUS networks is essential.

Key Functions
PROFIBUS to Serial Protocol Conversion: Facilitates real-time bidirectional data translation between PROFIBUS DP (supports master and slave modes, compliant with DP V0/V1) and serial communication standards (RS-232 and RS-485). Supports common serial protocols such as Modbus RTU, ASCII, and user-defined protocols, with configurable data mapping to align with specific application requirements. Transmission latency is <3ms, ensuring responsiveness in time-sensitive control tasks.
Dual Serial Interface Support: Equipped with versatile serial ports to accommodate diverse device connections:
1x RS-232 port (DB9 connector): Supports data rates up to 115.2 kbps, suitable for short-distance (up to 15m) point-to-point communication with devices like barcode scanners or local HMIs.
1x RS-485 port (terminal block): Supports data rates up to 115.2 kbps, enabling multi-drop networks (up to 32 devices) over longer distances (up to 1200m) for connecting sensors, valves, or remote I/O modules.
PROFIBUS DP Interface: Integrates a 9-pin D-Sub PROFIBUS DP connector (compliant with EN 50170) with auto-adaptive baud rates (9.6 kbps to 12 Mbps), ensuring compatibility with existing PROFIBUS networks and seamless integration with master controllers (e.g., Siemens S7 PLCs).
Redundant Power & Robust Protection: Features dual 24V DC power inputs (reverse polarity protected) to prevent system downtime from single power source failures. Supports a wide voltage range of 18-30V DC, adapting to unstable industrial power supplies. Over-voltage and over-current protection mechanisms safeguard both the gateway and connected devices.
Configuration & Diagnostics: Configurable via Hilscher’s SYCON.net software, allowing users to define data points, set serial parameters (parity, stop bits), and configure PROFIBUS addresses. Built-in diagnostics include real-time status monitoring (link integrity, error counts) and LED indicators (power, PROFIBUS activity, serial communication, faults) for quick on-site troubleshooting.
