Cross-platform replacement
A Modbus Slave alternative for macOS, Linux, and Windows.
Sykel Modbus Simulator is an independent, native Modbus device simulator for engineers looking beyond Modbus Slave, with compatible definition and workspace support and realistic fault injection.
Simulate the difficult cases
Build a useful device model—not only a static register table.
- Open compatible .mbs simulator definitions and .msw workspaces
- Model coils, discrete inputs, input registers, holding registers, and multiple devices
- Introduce response delays, dropped responses, bad checksums, and busy conditions
- Run natively on macOS, Linux, and Windows with the same local files
- Get Sykel Modbus Master in the same perpetual license
An independent alternative
Sykel is a clean-room product, not a rebrand or a plug-in. Modbus Slave 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.
