Real inputs via Profinet and slave in the same time

    Hello
    I have a robot Agilus with Profinet option on the arm. XPN41
    It's possible to read the inputs from sensors inside the controller KR4 via Profinet? or I have to connect the cable directly in the PLC and send back the signals state to the controller.
    The robot it's slave to a PLC Siemens via Profinet.
    The modul for inputs is: Impact20 ProfiNet-IO digital input module 16 digital inputs.
    If is possible please guide me.
    Thank you!

    there is no "profinet option in the arm". the port you are refereeing to (XPN41) just part of built in energy supply - this is just a 4-wire cable (and you can use it for what ever you like, does not need to be ProfiNet).

    To get your robot controller to support profinet, you must have ProfiNet software package installed and configured.

    What you are asking for is have two masters (PLC and KRC4) talking to same slave. I am not sure if this is sported on ProfiNet (it is in EthernetIP).
    If you ask me, keep it simple. have one master and if needed map signals through it.
    KRC4 can have dual role: be master and slave at the same time - IF installed version of ProfiNet is allowing it (Profinet is available in different editions: Controller/Device or just Device).

    This means that you can have few options:

    1. PLC is master, KRC4 and I/O are slaves (commonly used setup). You can share any PLC signal (including those from I/O) with KRC4.

    2. KRC4 is master, PLC and I/O are slaves. You can share any KRC4 signal (including those from I/O) with PLC.

    3. KRC4 is master to some I/O (such as your Impact20 module) and slave to PLC. PLC is master to other devices (other I/O and KRC4).

    etc.

    1) read pinned topic: READ FIRST...

    2) if you have an issue with robot, post question in the correct forum section... do NOT contact me directly

    3) read 1 and 2

    Thank you panic for your answer.
    I need this option.
    3. KRC4 is master to some I/O (such as your Impact20 module) and slave to PLC. PLC is master to other devices (other I/O and KRC4).
    etc.

    Does our controller support it? And which is the connection interface, I used X65 to communicate with pe PLC
