    Recommend for ease of use and stability. Works well with Free Pascal. Wishlist: Documentation. I'm sure Delphi ModBus TCP library does more than what I've got it doing right now. I'd love to be able to open up a manual, read it cover to cover and see what this thing can do when it is pushed to its limits. Comment: one of the dependencies for DelphiModBusLazarus has changed its name from 'pl_indycomp' to 'indylaz'. Took me a while to figure that out, but when I did, the library was ready to rock and roll. Change the name in project inspector and you're good to go. Just drop the control onto your form, follow the lead in one of the relevant examples and Voila! Modbus in your application!

    Very good library. It works very well with Delphi XE8 (Windows, Androïd and IOS). I hope a Delphi 10 Seattle compatible version will arrive soon.

    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

    I cannot run both demos together, tcpslave crashes after tcpmaster tries to read register. If i trying to write registers - data on tcpslave changes, but master says that operation was not succesful. Tried on Delphi7 and XE2, please help!!!
