18Software4. DiagnosisThe KEB F5 PROFINET operator offers two possibilities with the start-up tool KEB COMBIVIS to have access tothe parameters of the operator and the connected frequency inverter.4.1 Diagnosis via the diagnostic interface (X6B)Here the serial interface of a PC is connected with the diagnostic interface (X6B) of the KEB F5 PROFINET ope-rator with a special HSP5 cable (see order data). All parameters of the inverter control and the operator can beresponded with the start-up software KEB COMBIVIS.4.2 Diagnosis via the second EtherNet port parallel to PROFINET (X6C/X6D)If one of the both PROFINET ports (X6C or X6D) is not assigned by the PROFINET wiring this port can be con-nected with the EtherNet interface of a computer via EtherNet cable. Then KEB COMBIVIS can communicate viathis port with the PROFINET slave.The following must be considered at configuration of COMBIVIS:The IP address of the PROFINET slave must be entered at host in the menu Edit → Configuration → IP. Thisaddress is preset by the PROFINET master. The value can be read in the operator parameters as OS15Pnet_IPAddress.By setting the last digit of the host IP address to value = 255 in the IP configuration of COMBIVIS one ensuresthat COMBIVIS can address several connected IP devices whose IP address is in the range 192.10.1.x.
