Some problems with config files when I use ros2_canopen in combination with diff_drive_controller, the terminal output is "command interface already in available list. This can happen due to multiple calls to 'configure'". #291

Describe the problems Hi,

I'm a student and I'm trying to use diff_drive_controller with ros2_canopen, I followed the tutorials about ros2_canopen and ros2_control, I referenced the config files the sample program from github.

Problem: When I run the program, ros2 diff_drive_controller and ros2_canoepn work fine respectively. When I call 

ros2 topic pub --rate 30 /diffbot_base_controller/cmd_vel geometry_msgs/msg/TwistStamped "
twist:
  linear:
    x: 0.7
    y: 0.0
    z: 0.0
  angular:
    x: 0.0
    y: 0.0
    z: 1.0"

the robot in rviz turned normally, but wheels that ros2_canopen drives are not turning. Some of the files are not configured correctly, but I don't know how to configure them correctly.

the terminal output is 

[ros2_control_node-3] [WARN] [1720421078.777601620] [resource_manager]: (hardware 'diff_robot'): 'left_wheel_joint/position' state interface already in available list. This can happen due to multiple calls to 'configure'

Environment :

I tried many times but I can not config it correctly. Could you please help me?

你用的是虚拟can和虚拟的两个从机 所以不动

Yes, I am using a virtual CAN interface. When I check the status of the joints, the virtual CAN interface is theoretically working fine. But currently ROS2_CANOPEN and ROS2_diff_controller are working fine respectively, but the state and command interface are duplicated and configured. As the terminal output said "This can happen due to multiple calls to 'configure'".

I am still trying to solve this problem but I can not configure it properly.

Thanks for your reply!
