A standard profibus cable can be used to connect a Siemens S7-300 series processor to a proface display. The Siemens standard port on the S7-300 is Siemens MPI protocol. You can get the profibus quick connectors from Siemens as well as the profibus cable.

If your connecting a S7-300 PLC to a proface display, the profibus cable and connectors will work. Although your not running profibus, the wiring for MPI is the same. I have a S7-312 Siemens PLC connected to a Proface model AST3211 using th Siemens profibus cables and quick connectors and it works fine.
