Hello everyone,
I have an Ewon Flexy 203 with HMI KTP 700 Basic DP and a PLC IM 151-7 CPU. The communication is done as follows.
The Flexy 203 is connected to the PLC, and the PLC in turn is connected to the HMI. All communication is by MPI. The MPI address of the PLC is 2, that of the ewon is 29 and that of the screen is 1.
The PLC and the EWON connect successfully, but the HMI does not. I don’t know what I’m doing wrong, or if the HMI can really have online access, both to view the data by using a program like VNC Viewer, and to upload data, well, if I want to update remotely Currently I can’t, I can only do it to the PLC.
Thank you very much in advance,
If something occurs to you, tell me.
All the best,
Samuel
