We are developing a set of Delphi components to communicate with a ModBus PLC over TCP/IP. The library provides components to implement both a ModBus master and a Modbus slave, and is based on the Indy component set (both Indy 9 and 10 are supported)
De source code of the project has been moved to GitHub!
- Supports Delphi 5 and higher
- Implements Modbus TCP master and slave
That's a great library. Here are some Modbus drivers and other libraries for reference: icpdas- usa.com/utility_and_software_develop_toolkit_for_7000_8000_87000_i_o_modules_with_dcon_protocol_.html?r=maria
Excelent library! Will there be a Delphi XE7 release? /Per
Work using the demos. But on real PLC, I can't get register value or write value, please help...
Delphimodbus works great.
This is a very useful and complete set of componentes. Great job
