Read multiple server modbus

[Elmatbaisaad]

Hello everyone !
I m working in project using symfony and docker and i have three Modbus servers which they have the same ip adress but different ports when i launch the application it connects to the servers because i can define to wich server it should be connected .
the probleme is that i when connect the application to the three servers in the same time it connects but it display 0 as value for the registers and coils.
should I create a container for each server or there is a solution for that ?
Thank you!

are you really sure that this docker block instructs that python script to spawn listener on 3 ports? For me it seems only to say that map 3 ports from your host to docker container and run some python file. Now that python file that you screenshoted seems to spawn only one server.

you could always bash/sh into that python container and see if python is really listening on 3 separate ports.
