Hello, look, I'm reading a few meters through RTU but I need many registers to read, I tried to put several queries in packets of maximum 60 but I see that when placing several it does not read if not the first one. My question is how do I read various information packets from modbus registers?

Could You upload the project somwhere for testing?

[bacemex]

Hello Kurt, it is possible you can share the program (text is OK) for test purposes?

there is a chance to show how to do the same thing, with the same configuration, but in codesys 3.5?

I have 4 slaves of the same type, I am trying to make interrupt functions but the code is very confusing

Thank you Kurt Braun
if I have multi slaves connected to 750-652 and I need to read same register from them.
can I use one instance of FbMbMasterSerial and just change bUnitId from array
or its better to use FbMbMasterSerial for each slave ?

Can you load the project or just text to your github account?

Hi, you are amazing, but I have a request. Would you please help to use one Wago as master and the other one as slave just by them connecting to the internet. Meaning that Wago devices have no connection to each other and just by IP addresses they can communicate via inetrnet. I really appreciate it.

How did you declare parameters and program all codes at the same time and paste it so quickly?

Why is everything programmed in ST today? To make the program easier to read, FUP is always preferred. Try to implement the project in FUP and the YouTube viewers will thank you.

I thin when you make a lesson please slow down. This is wasting of time
