W&T 58631 Communication Server – Serial to Ethernet Gateway | Com-Server Family
Engineering Background: Industrial automation networks increasingly demand seamless integration between legacy serial devices and modern Ethernet/IP infrastructure. The W&T 58631 bridges this gap as a high-performance serial-to-Ethernet gateway engineered by Wiesemann & Theis (W&T), a German manufacturer with over 40 years of industrial connectivity expertise.
Product Positioning: The 58631 is purpose-built for procurement engineers and system integrators who need a reliable, DIN-rail-mountable communication server to connect RS-232/RS-422/RS-485 serial devices to TCP/IP networks without modifying existing field equipment. It is a core component of W&T’s Com-Server family, trusted in SCADA, PLC, and building automation environments worldwide.

- Industrial-Grade Reliability: Designed for 24/7 continuous operation in harsh industrial environments
- German Engineering: Manufactured and quality-controlled in Germany to IEC industrial standards
System Architecture & Signal Flow
The W&T 58631 operates as a transparent protocol converter. Serial data from field devices (RS-232/422/485) is encapsulated into TCP/IP or UDP packets and transmitted across the Ethernet backbone to host systems, SCADA servers, or peer devices. The reverse path is equally transparent. Configuration is performed via the embedded web server (HTTP) or via W&T’s WuTility network management tool. The device supports both client and server TCP modes, enabling flexible point-to-point and point-to-multipoint topologies.

Technical FAQ
Q: Can the 58631 handle RS-485 multi-drop networks?
A: Yes. The RS-485 interface supports multi-drop bus topologies with up to 32 nodes at baud rates up to 115,200 bps.
Q: Is the device compatible with Modbus TCP?
A: The 58631 provides transparent serial tunneling; Modbus RTU frames are encapsulated in TCP, making it compatible with Modbus TCP gateways and SCADA drivers that support this mode.
Q: What configuration software is required?
A: No proprietary software is required. Configuration is accessible via any web browser through the built-in HTTP server. W&T’s free WuTility tool is optionally available for network-wide device discovery.
Q: Is the unit suitable for 24/7 industrial operation?
A: Yes. The 58631 is rated for continuous operation at 0–55 °C with no scheduled maintenance intervals.
Q: Can I get a datasheet or CE declaration?
A: Yes. Contact support@konmask.com and we will provide the official W&T datasheet, CE declaration, and wiring diagrams.
