S7-300 (DP) communication with FUXA

[Ckostopoulos]

Hello community,

I recently started a project in which I would like to connect my S7-313 2DP CPU (Via PROFIBUS - CP5711) to TIA Portal and then using as HMI FUXA. My questions now are:

1. Is it possible to connect with FUXA when my connection is via profibus? (Because profibus has no IP address but node address).
2. Will I need OPC UA for the connection?

(I just need FUXA for some basic buttons (e.g. Start, Stop of motors) and Visualize some graphs (e.g. motor speed).

If someone knows how this procedure could be done, please let me know.

Thank you!

@Ckostopoulos you need to do more research about Profibus, it's not an ethernet based protocol but an serial protocol on the RS485 physical layer. Only the S7-1200 and S7-1500 support OPC-UA. You will need a protocol converter in order to do this. Profibus to Profinet or OPC-UA

One way to connect is that you buy Helmholz NetLink which converts Serial communication to Ethernet communication. You will be able to connect via S7 driver then which is available in FUXA
