C/C++ Modbus TCP

Cross-platform low-level Modbus TCP streaming example written in C/C++ for the LabJack T7 or T4. The C/C++ Modbus TCP functionality used in the example is provided by LabJack. These Modbus functions, provided in modbus.h/.c, in general can be used for Modbus TCP operations and not just for streaming.

Refer to the README.TXT in the download/attachment below for more details.

Note: This is an advanced example for users who can't use the cross-platform LJM library we provide. In most cases using the LJM library is an option and we recommend using its stream functions and examples for ease of use.
