Key Functions
Serial to Ethernet Protocol Conversion: Facilitates real-time bidirectional data translation between serial communication standards (RS-232/RS-485) and Ethernet-based protocols (Modbus TCP/IP, PROFINET). Supports popular serial protocols including Modbus RTU, ASCII, and custom user-defined protocols, with configurable data mapping to align with specific application requirements. Transmission latency is <2ms, ensuring responsiveness in time-critical control tasks.
Dual Serial Interface Support: Equipped with flexible serial ports to connect diverse devices:
1x RS-232 port (DB9 connector): Supports data rates up to 115.2 kbps, ideal for short-distance (up to 15m) point-to-point communication with devices like barcode scanners, HMIs, or legacy controllers.
1x RS-485 port (terminal block): Supports data rates up to 115.2 kbps, enabling multi-drop networks (up to 32 devices) over extended distances (up to 1200m) for connecting sensors, meters, valves, or remote I/O modules.
Ethernet Interface Configuration: Integrates 2x RJ45 Ethernet ports (10/100 Mbps) supporting both Modbus TCP/IP and PROFINET IO (device/controller mode). Enables flexible network topologies (star or daisy-chain) and simplified wiring, with auto-negotiation for seamless integration into existing Ethernet networks.
Redundant Power & Protection Mechanisms: 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 safeguard the gateway and connected equipment.
Configuration & Diagnostics: Configurable via Hilscher’s SYCON.net software, allowing users to set serial parameters (baud rate, parity, stop bits), define Ethernet protocols, and map data points. Built-in diagnostics include real-time status monitoring (link quality, error rates) and LED indicators (power, Ethernet activity, serial communication, faults) for quick on-site troubleshooting.
Ethernet: Modbus TCP/IP, PROFINET IO (compliant with PROFINET RT).
Compatible Devices:
Serial equipment: RS-232/RS-485 sensors, meters, actuators, barcode readers, and legacy PLCs.
Ethernet systems: Compatible with major industrial control systems (e.g., Siemens SIMATIC, Rockwell Allen-Bradley, Schneider Modicon) and SCADA/HMI platforms.
