A simple Modbus TCP gateway server tool to share regsiters between processes and systems.
I use the very good and concise libmodbus library (https://github.com/stephane/libmodbus) to handle the Modbus part. It simply works.
The tool spawns a Modbus TCP server that supports up to 10 clients (for now). The clients just use the holding registers as shared data. Dpo whatever you want with it. I will add some read-only feature soon.
