Built on the Tibbo TPP2W(G2) programmable platform

Bridge every Modbus network — TCP, RTU & ASCII — on one gateway.

Connect serial field devices to your SCADA, PLC, or cloud without rewiring or rewriting protocol logic. Four independent Modbus channels, Ethernet and Wi-Fi, and a live LCD status screen — configurable in minutes.

Why engineers choose it

Protocol translation that just works on the plant floor.

Point a Modbus TCP master at a legacy RS-485 slave, or expose serial meters to a cloud gateway. The routing, framing, and timeout handling are done for you.

Any-to-any Modbus routing

Route requests and replies between Modbus TCP, Modbus RTU, and Modbus ASCII masters and slaves — mix and match per channel.

🔀

4 concurrent channels

Each channel has its own listening port, protocol, serial settings, and mapped target devices — run four segregated links at once.

🔌

Serial done right

RS-232 and RS-485 via the Tibbit 05 module, with independent baud rate, parity, data bits, and flow control per port.

📶

Ethernet & Wi-Fi

Wire it into your control network or drop it onto plant Wi-Fi. DHCP or static addressing on both interfaces.

🖥️

Live LCD status

Read IP, link state, and traffic health right on the device — no laptop needed for a quick health check in the field.

🛠️

Programmable platform

Built on Tibbo's TPP2W(G2) and AppBlocks. When your application needs a tweak, the logic is open to extend — not a black box.

Configure from any browser

A built-in Device Console — no software to install.

Point a browser at the gateway's IP and you get a password-protected web console for network setup, per-channel serial parameters, and live diagnostics. Import and export the full configuration to roll it out across a fleet.

🔒 192.168.1.125/settings
Device Console Settings page, General tab: Ethernet DHCP enabled, IP 192.168.1.125, netmask 255.255.255.0, gateway 192.168.1.1, with Save, Refresh, Export and Import buttons

Network settings. Ethernet and Wi-Fi addressing — DHCP or static IP, netmask, and gateway — configured right from the General tab.

One page, three stakeholders

Answers for everyone in the decision.

Controls / Automation Engineer

  • Bridge legacy RS-485 devices to Modbus TCP masters
  • Per-channel protocol, port, and serial parameters
  • Configurable Modbus timeout for slow slaves
  • On-device LCD for fast field diagnostics

Integrator / OEM

  • Programmable AppBlocks logic you can extend
  • Consistent Tibbo hardware you can standardize on
  • Ethernet + Wi-Fi covers wired and retrofit sites
  • Reusable across multiple client deployments

Plant / Project Manager

  • Cut integration time — no custom protocol code
  • Retrofit existing equipment instead of replacing it
  • Application engineer support from Tibbo
  • One SKU handles TCP, RTU, and ASCII sites
