AXC F 2152 Network Configuration: PROFINET or Ethernet/IP or TCP/IP or MODBUS

What is the easiest and most robust way to connect different devices to AXC F 2152? I am trying to select a device to connect it to AXC F 2152, but different versions of the same device support MODBUS, PROFINET, Ethernet/IP, and TCP/IP. Which one should I go with? After reading a bit, it seems PROFINET is the easiest one to set it up regarding programming, but I just want to be sure. I would appreciate it if you can point me to further resources to read about this subject if there are any.

Thank you very much! :)

    I'm sure there are many and varied opinions on this question, but here's my 2 cents:

    - TCP/IP: A low level Ethernet protocol that could be implemented in PLCnext Control devices without too much effort. Probably simple to implement basic functions, but it won't have the same features as the other (higher-level) fieldbus protocols.

    - Modbus/TCP (I guess you don't mean Modbus/RTU): A good, solid, fairly simple protocol that has been around for years, popular among all PLC vendors but especially Schneider (in my experience), and popular in utilities like Water and Energy. In PLCnext Control devices, Modbus is not supported "natively", and requires the use of additional Function Block libraries, which some people may find more complicated than the other fieldbus communication options.

    - Ethernet/IP: Championed by Rockwell / Allen-Bradley. Limited support in PLCnext Control devices, and probably not the best choice for a PLCnext Control application where the PLC is acting as the fieldbus master.

    - Profinet: Championed by Siemens and Phoenix Contact, and fully integrated in PLCnext Control devices and PLCnext Engineer. This would probably be the best choice for a PLCnext Control application, especially if it is an industrial application. You should make yourself familiar with the Profinet Engineering and Installation guidelines, e.g. network design and installation, which may avoid some of the more common issues that people have with Profinet applications. You can search for training courses on the Profinet website (https://www.profibus.com/), and even get Profinet certification for yourself, if you want.

    Hi Martin,

    This is the information I needed. Thanks a lot!
