Know what the bus is saying.
Poll and write Modbus data, inspect traffic, chart live values, scan networks, and test the protocol from one native application on macOS, Linux, or Windows.
Observe, diagnose, and act without changing context.
- Multiple independent polling windows on one connection
- RTU, ASCII, TCP, UDP, RTU/ASCII over sockets, and TLS
- Traffic view, Test Center, address and device scans
- Real-time charts, CSV/XLSX logging, and exports
- Scaling, byte order, display formats, named values, and conditional color
Open the work you already have
Sykel Modbus Master reads compatible .mbp poll definitions and .mbw workspaces, including supported historical binary formats. Definitions retain the things engineers configure: address, function, quantities, grid configuration, formats, scales, names, colors, and chart links.
Considering a Modbus Poll alternative?
Move to a native Mac, Linux, or modern Windows workflow while keeping your projects close at hand. Compare the practical migration path before rebuilding an established bench setup.
Designed for test automation too
Use the local, token-protected JSON control API over stdio, localhost TCP, or a Unix socket. Master operations can participate in a test bench without turning a desktop app into a cloud service.
