Modbus RTU Master Implementation in Python - Read Data from Modbus RTU Slave

[@elizasapkota2785]

Before running this program, do we need to connect the controller to the device(slave) with any ideal(organisational) software and then only use Python for further control? Although my computer is connected to the controller then controller cannot communicate with the slave(linear motor in my case). what would you suggest, I should do?

It should actually connect. Sometimes you may use a Modbus TCP Master to Troubleshoot but it is not necessary. I wonder why its not working for you. Can you provide more details about your setup and code as well?

Hi, thank you so much for the video. Seems you have another video that introduces how to implement a RTU slave. I can not find it anywhere, can you share the code or the video to me ? thank you so much !!!

yes, here is the video: kzbin.info/www/bejne/pH2QlYVubMl7hdk

@@brightersidehacks Thank you! May I simulate a RTU slave using python since I do not have an Arduino? Cannot find an instruction anywhere....

Hi, do you have a video about how to implement the slave with python?
