SMG-5410 – RS232 Modbus Gateway

SMG-5410 is an industrial Modbus Gateway that converts and routes Modbus data between the serial line and Modbus/TCP. It’s ideal for integrating RS232 Modbus RTU/ASCII sensors and devices into Ethernet-based SCADA/HMI systems—without changing your legacy field equipment.

Key features of the SMG-5410

  • • Converts and routes Modbus data between RS232 (Modbus RTU/ASCII) and Modbus/TCP.
  • • Supports multiple TCP connections (up to 4 channels) for flexible client access.
  • • Transmission modes: Modbus/RTU, Modbus/ASCII, and Bypass for non-Modbus serial payload forwarding.
  • • IPv4/IPv6 dual stack support and SSL/TLS-capable networking functions.
  • • Reverse voltage & surge protection for improved robustness in field installations.

Integrating the SMG-5410 with SCADA / HMI / PLC systems

Use any standard Modbus/TCP client (SCADA, HMI, PLC or software tools) to poll serial Modbus devices through Ethernet. SMG-5410 bridges the protocol gap so your existing RS232 Modbus RTU/ASCII equipment becomes IP-accessible.

  • • Choose TCP→Serial or Serial→TCP query flow depending on your system architecture.
  • • Fine-tune response timeouts to match slower serial devices and improve reliability.
Protocol bridge
Connect Modbus RTU/ASCII devices to Modbus/TCP networks without redesigning your existing serial field wiring.
RS232 (D-Sub)
Classic RS232 interface for Modbus devices and instruments—simple retrofits for legacy systems.
Ethernet access
10/100 Ethernet makes serial Modbus data available to multiple clients across the LAN.
Multi-connection
Supports up to 4 TCP channels for service tools, SCADA and engineering access in parallel.
Security & management
Password protection and easy configuration/monitoring via spFinder.
Built for harsh sites
Industrial temperature range and protection circuitry help ensure stable operation in demanding environments.
