fortran-modbus

A collection of Fortran 2018 interface bindings to libmodbus, for Modbus RTU and Modbus TCP access.

Build Instructions

The package libmodbus has to be installed with development headers. On FreeBSD, run:

# pkg install comms/libmodbus

On Linux, instead:

# apt-get install libmodbus5 libmodbus-dev

Build and install the Fortran library using the provided Makefile:

$ make
$ make install PREFIX=/opt

Link your programs against /opt/lib/libfortran-modbus.a -lmodbus. Optionally, overwrite the default compiler and the compiler flags:

$ make FC=ifx FFLAGS="-O3"

Or, use the Fortran Package Manager:

$ fpm build --profile release

Build and run the test program:

$ make test
$ ./test_modbus

Fortran Package Manager

You can add fortran-modbus as an FPM dependency:
