DIP switch S101

The DIP switches have the following meaning for the switched Ethernet interfaces X101 and X102.

Position of the DIP switches: left OFF (0), right ON (1).
DIP 9	DIP 10	Description DIP 1…8	Restart behavior	Behavior with factory settings
OFF (0)	OFF (0)	Last byte of the IP address via DIP switches 1 to 8	PN name from memory IP address via DIP switches 1 to 8	PN name becomes empty string IP address via DIP switches 172.16.17.xxx (xxx DIP switch) SNM 255.255.0.0
OFF (0)	ON (1)	DHCP DIP switches 1 to 8 set to OFF	PN name from memory IP address and SNM via DHCP	PN name becomes an empty string IP address and SNM via DHCP
OFF (0)	ON (1)	DHCP DIP switches 1 to 8 set to ON	PN name via DIP switches 1 to 8 IP address and SNM via DHCP	PN name via DIP switches 1 to 8 IP address and SNM via DHCP
ON (1)	OFF (0)	reserved	-	-
ON (1)	ON (1)	PROFINET-compliant DIP switches 1 to 8 set to OFF	PN name from memory IP address from memory PROFINET name can be specified via the TwinCAT System Manager.	PN name becomes empty string IP address 0.0.0.0
ON (1)	ON (1)	PROFINET with fixed name DIP switches 1 to 8 set to ON	PN name via DIP switches 1 to 8 IP address from memory PROFINET name can be specified via the TwinCAT System Manager.	PN name via DIP switches 1 to 8 IP address 0.0.0.0

Setting PROFINET names

If DIP switches 9 and 10 are set to ON, the PROFINET name is formed from "CX7293-" and the position of DIP switches 1 to 8. At least one of the DIP switches 1 to 8 must be set to ON. Example – DIP 9 and 10: ON – DIP 1 and 2: ON – DIP 3 to 8: OFF results in the PROFINET name CX7293-3.
