MBM
Description
MBM is free Modbus master simulation software. This software is designed for quick and simple testing of Modbus slave devices provides single and multiple read/write manual actions and pool modus for read actions.Supported Modbus functions
- 01: Read coil status
- 02: Read input status
- 03: Read holding register
- 04: Read input registers
- 05: Force single coil
- 06: Preset single register
- 15: Force multiple coils
- 16: Preset multiple registers
Features
- Easy-to-use intuitive GUI
- XML device configurations
- Can display fixed point values
MBM has Qt based single window user interface. All devices can be load form XML configuration in separates tabs.
MBM has a log window to display timing and exception information.

XML device configuration
XML device configuration defines slave address, registers (holding / input registers) and discretes (coils and statuses). For transaction optimization registers and discretes can be grouped.Device configuration example
