6, Delphi, vb. Dll in the c # program editor within ACE development platform and I do not. The driver implements the Modicon Modbus protocol stack over TCP. A free Modbus ASCII/RTU and TCP implementation. I finished writing a Modbus Master Driver for the OpenPLC. It means that you can now use your Modbus Slave device as an I/O for the OpenPLC soft-core running in your PC. The driver supports Modbus TCP and RTU, although I haven't tested the RTU mode yet because I don't have any RTU device.

About

The PascalSCADA package is a set of components for Delphi/Lazarus to make easy the development of industrial applications which need to interact with PLC's and devices of many manufactures. It is available for Windows(32 and 64 bits), Linux (32 and 64 bits), macOS, Solaris and FreeBSD (32 bits) and provides port drivers (serial, ethernet), protocol drivers (Modbus RTU, ModBus TCP, West ASCII, Ibox and Siemens ISOTCP), tags (numeric, string, block) and controls (edit, labels, progressbar, animations). Historics, recipes and User management will be coming soon.
