Modbus protocol

Dear Expert.
In my project, I use modbus protocol as below diagram

I have 3 Modbus RTU slave device connected to Modbus gateway. After that I use factory studio for reading realtime data. I create 3 nodes and assign them into a node. Please see my confjgurator at below.

But when Rumtime, Factory studio just only read one Modbus RTU device.
I guessed that, I was wrong somewhere.
Please help me to find out it.

Hi Manh,

Hope this message finds you well. Would it be possible for you to share the .tproj file of your current project with us? Additionally, could you please provide us with the trace window log, making sure that the following options are checked?

By doing so, we can assist you in identifying the cause of the issue.

Best Regards,
