modbus-utils

Modbus client and server command line tools based on libmodbus.

NOTE: Both apps are linked with libmodbus library. After repository is pulled do the following:

compilation

option 1 (cmake)

$ git clone https://github.com/Krzysztow/modbus-utils
$ cd modbus-utils
$ git submodule update --init
$ mkdir build
$ cd build
$ cmake ..
$ make

option 2

#assumes you are in a root of the repository

#go to libmodbus dir and compile it

cd ./libmodbus ./configure ./make

#as a result *.so libraries are in export ./src/.libs/ directory

#get back to the root

cd .. gcc ./modbus_client/modbus_client.c -I./common -I./libmodbus/src/ -L./libmodbus/src/.libs/ -lmodbus -o mbClient gcc ./modbus_server/modbus_server.c -I./common -I./libmodbus/src/ -L./libmodbus/src/.libs/ -lmodbus -o mbServer

running

If modbus libraries are not in a default location (either it's needed to move libraries to app location or set appropriate environment variable):

  • on linux it would be:
    1. LD_LIBRARY_PATH=./libmodbus/src/.libs/ ./mbClient OR
    2. export LD_LIBRARY_PATH=./libmodbus/src/.libs/ and then run ./mbClient

usage

Run apps with no arguments, descriptive help information will be provided.
