Hello, thank you very much for the help.. I have tried some codes but I always have the same error. Does anyone know what is happening?

Error: piControlGetVariableInfo() returned 14 for variable ' '

Hi Dirk, thank you so much for your help as always.
In this case, I need a switch to work like this. Is there a code where I can just read the data from Pictory?

Instead of using "piTest -r Input_1", I was wondering if there is a simple c code that can also get this value from my pictory?

I think my QModMaster is not reading values because the gateway component is in one network "192.168.0.X" and my RevPi is in another "192.168.88.X" So, I decided to change the IP of my router automatically to the 192.168.0.X range, I thought that after that, I would have a new IP...

8e89bf6679ea54c3-photo-full.jpg Hello, thank you so much for helping me! So for example, in this case, since my IP is 192.168.88.x, I have 192.168.88.16 ? Unfortunately I still couldnt access the website. And about the QModMaster, in the TCP section, should I put the gateway component IP? Or should...

I have seen the 5.3 section, but I do not know the address of my gateway component. My default gateway has the IP address "192.168.88.1". So I believe that my gateway component has the IP "192.168.88.x"? but how can I found out x? Also, how can I know the IP addresses of the DIP ...

Does anyone know why I cant read values from my Gateway Modbus TCP, using QModMaster?

They are in the same network. Using your last example to explain better.. My RevPi Core 1 is using the IP address of the RevPi Core 2 on pictory. All of this to get the data from this slave. But this is not working, maybe the IP address has to be from some of the Modbus TCP gateways? Maybe my cable ...

This is the link of an image with my hardware configuration: https://uploaddeimagens.com.br/imagens/KuM-cTQ on the right side, I have a Revpi core 3 and a gatewaymodule TCP. I configured it on pictory as Master TCP. On the left side, I have another Revpi core 3 and another gatewaymodule TCP. I confi...

Hello Dirk, thank you for the reply! I have already checked both tutorials. And I will download what you have mentioned. But instead of using a program to communicate with my Master revpi, and using another program to communicate with my Slave revpi, cant they communicate together just using pictory...
