I am not able to Start a modbus server using the command $ rosrun modbus_wrapper modbus_server.py _port:=1234 because "modbus_wrapper" is not found. how can I solve this issue? I tried using "modbus_wrapper_server,py" instead of "modbus_wrapper" but still no use

Hi,

First make sure you have catkin_make your workspace:
cd ros_ws
catkin_make
And then make sure to source the built workspace:
source devel/setup.bash
Now you should be able to run:
rosrun modbus modbus_server.py

modbus_wrapper is not the name of a ROS package but of the built and installed python library.
