Why teams switch

One tool, not a drawer of them

More than Modbus

One tool that also decodes DLMS, M-Bus, IEC 62056-21 and MASS — not a Modbus-only poller.

Watch real traffic

Passively monitor and sniff an existing line, not just act as a master that generates polls.

Windows and Linux

Run the same tool on your laptop and on a Linux bench or edge box.

Flows + AI

Automate with flows and let an AI agent build and run tests over MCP.

Where Modbus Poll fits

Modbus Poll (from Modbus Tools) is a focused, well-loved Modbus master with a tidy read/write grid and a companion slave simulator. If your work is purely Modbus master/slave on Windows, it does that job well. Omni Console is the better fit when you need to monitor and decode real traffic, work across several protocols, sniff a live line, or run on Linux — without piecing several tools together.

Is Omni Console a drop-in Modbus Poll replacement?

For monitoring, decoding and building Modbus frames across RTU/ASCII/TCP it covers the same ground, and adds passive sniffing, an online device library, other protocols, flows and AI control. Modbus Poll remains a focused, mature Modbus master with its companion slave simulator.

Can it poll a Modbus device like a master?

Yes — build and send Modbus requests (FC 01–06, 0F, 10) and read the decoded responses. See the Modbus page.

Does it read other protocols too?

Yes — DLMS/COSEM, M-Bus, IEC 62056-21 and MASS, plus raw decoding of any serial line. See features.
