Hello franckaay roy,

you did not specify your CPU and your panel, but most CPUs of 300 series have possibility to connect via MPI or Profibus DP. Some also are able to connect via ProfiNet.

Depending on type of connection, you will have different cable.

If you have your CPU connected via Profibus already to other devices, you might want to use display as part of Profibus also and thus use same cables.

regards

Hello franckaay roy,

in your case you will have to use standard MPI cable, as your CPU does not support any other. Be aware that both products you stated are already outdated. Thats why you could not find any sata I guess.

See here the manual for your CPU:

PLC S7-300, CPU Specifications CPU 312 IFM to CPU 318-2 DP
