SnapModbus is an Open-Source multi-platform suite (library and tools) to manage Modbus communication in strict adherence to the modbus.org specifications, both master and slave side. It supports all the functions described in the documents:
* MODBUS APPLICATION PROTOCOL SPECIFICATION V1.1b3
* MODBUS MESSAGING ON TCP/IP IMPLEMENTATION GUIDE V1.0b
* MODBUS over Serial Line - Specification and Implementation Guide V1.02
through the standard transport protocols and the most widespread unofficial protocols (UDP, RTU Over TCP, RTU Over UDP)
It’s released under lglp v3, so it’s free also for commercial use.
Features
- Native multi-architecture design (32/64 bit)
- Complete adherence to Modbus specifications and complete implementation of functions
- Can read up to 65535 registers/bit with a single call.
- Fully thread-safe
- Optimized procedures for serial adapters management
- Data consistency is always guaranteed both at the device and application level
- Advanced debugging and raw transfer functions that allow the experimentation and implementation of particular software using few lines of code (gateways or protocol converters)
