Protocol Converters
TCP/IP Modbus TCP ⇄ RTU Converter
Bridge serial Modbus RTU equipment to Ethernet — in both directions. Three operating modes cover master, slave and fully transparent serial, while the built-in web portal handles configuration, firmware updates and diagnostics remotely. No protocol expertise needed.

Watch the packet — it leaves as a blue Modbus TCP frame, crosses the WE62C, and continues as an amber Modbus RTU frame. Same request, two languages — and the reply comes back the same way.
The converter is not locked to one direction. A dropdown in its web interface switches the role — Modbus TCP to RTU gateway, RTU to remote TCP client, or a fully transparent serial tunnel — so the same hardware fits whichever side of the network your equipment sits on.
Modbus Slave · TCP Master (server) — SCADA polls your RS-485 bus
WE62CUSE IT WHEN your SCADA or software speaks Modbus TCP, but the meters live on an RS-485 serial bus.
Modbus Master · TCP Slave (client) — your PLC reaches remote devices
WE62CUSE IT WHEN a serial PLC or RTU master must read devices that sit across the LAN or at a remote site.
Transparent mode — a raw serial tunnel over Ethernet
WE62CUSE IT WHEN existing serial software must reach a distant serial device over the network — bytes untouched.
Connection role — TCP Server or TCP Client, your choice
WE62CThe WE62C listens on its local port and waits — the remote application (or SCADA) opens the connection to it. Best when the device has a fixed, reachable IP on the LAN.
WE62CThe WE62C dials out to a configured server IP and port — ideal when the device sits behind a router or on cellular, reaching a cloud or central server that cannot reach back in.
One setting does it: choose Cont. Protocol → Server or Client in the web interface. It applies to transparent mode and the Modbus modes alike — the same flexibility whether the WE62C waits for connections or initiates them.
Every setting lives in the converter’s own web pages — network, operating mode, COM settings, unit ID and timeouts — plus a live Modbus traffic monitor, a console, and config-file backup and restore for cloning settings across units.
