Hello.
Thanks to Claes, I was able to start the project. It works fine for over a year. It consists of a processing station on raspberry pi, attached to it is 12 modbus modules.
Now I wanted to broaden my knowledge and build a new, more advanced project.
PLAN
1 - ubuntu development server 16.04 64bit
2 process station raspberry pi 3
3- storage ubuntu 16.04 64bit
4 operator as client through browser
I do not understand where in the project put a storage server instance and where to add the ability to view historical data from analog inputs.
It would help the outline of the project.
If someone can send me a screenshot of a visible data server, I will be very grateful.
Regards
