Manual.

[Slavko Kocjancic]

Hello...

I look for manual for modbus-tk but can't find it.
Is it non existing?!?

Slavko.

Hi Slavko.

I do believe that there isn't a "manual" documentation (something like a PDF document) on the usage of modbus-tk.

As you should know the resources and infos about modbus-tk can be found at this link . ;-)

I know for that link.
But actualy there are no manual. And most examples doesn't work. Digging
into source to understand what and how to do is little to much for my
level of knowledge. Seems that I should pick some other library with manual.

Hi Slavko.
Did you get a look at the Wiki pages.

There are pages for examples on Master and Slave (Server) application.

I'm not a Python expert but believe me .... I get modbus-tk working quite easily .

I agree with you that the documentation is a bit "essential" but I do believe that modbus-tk is a good Python module for writing modbus applications .

Hello Slavko,

I agree that documentation is a "must-have" and that modbus-tk must be improved to explain better how to use it. Unfortunately, I would need time to work on it and I don't have it currently.

I would welcome anyone who is able to help on this topic :) 

The wiki and the examples tries to be a starting point for this doc and this mailing list where to ask for help.

Can you please try to explain what is going wrong when getting started so we can try to help you.

Best

I got working solution based from examples, but it's not easy.
I stuck with modbus_tk as seems that other libraryes are only for master
or slave but not both.

Good to know that you succeed and welcome to the modbus_tk users. 

Feel free to contribute by giving some feedback about the troubles you had when getting started.

Hello..
Actually still have trouble.
For now I run rtu server.
I just do the GUI for my plc simulator. And seems to work nice in one
direction. When I change input or coil on simulator I got correct
reading on scada program on other side. But when I update coil from
scada the my simulator GUI isn't updated.

How to setup some kind of callback when coil is updated from scada?
Slavko.

I had some success with modbus_tk, and I wrote an article on what I did here: https://www.linkedin.com/pulse/how-get-python-modbustk-modbus-rtu-simulator-working-tony-nordstrom/
