Cross-platform replacement
A Modbus Poll alternative for macOS, Linux, and Windows.
Sykel Modbus Master is an independent, native Modbus master application for engineers looking beyond Modbus Poll—without abandoning practical project-file compatibility or keyboard-driven workflows.
Keep the engineering context
Move to the platform you use without starting your Modbus work from scratch.
- Open compatible .mbp poll definitions and .mbw workspaces
- Poll, write, scan, inspect traffic, chart live values, and test functions directly
- Use the same tool on a Mac laptop, Linux test rig, or Windows workstation
- Keep activation offline, with no account login or recurring validation
- Get Sykel Modbus Simulator in the same perpetual license
An independent alternative
Sykel is a clean-room product, not a rebrand or a plug-in. Modbus Poll is a trademark of its respective owner; Sykel does not claim affiliation or endorsement. Compatible file support is provided so engineers can keep working with their own existing projects.
One bundle, not a menu
Every license includes both Sykel Modbus Master and Sykel Modbus Simulator. The two tools share the same compatible project model, technical visual language, and perpetual offline licensing.
