Hello, I would like to know if I can use schema like this one I attached? Is it possible to use PROFINET and MODBUS TCP simultaneously in one CPU with 2 PN ports? Are all of these components connected properly? Please, help me explain my doubts. Regards

HelloKrzysztof M.,
To the best of my knowledge, It is possible. For more info on how to establish the Modbus TCP connection with H CPUs, please check this,
As recommended byMaraitorzzzzzIt is better to use switches to have better availability. I've change your configuration a bit so you can use it If you still do not want to use switches. Just take care that having switches doesn't mean your job is over. Note in the Modbus TCP above link: Using the "Modbus_PN_CPU" library blocks it is possible to establish a redundant Modbus/TCP communication over the integrated PROFINET interface of a CPU 41x-H. The redundancy function must be programmed by the user. Best regards. H-H
