DIP switch

CAUTION

DIP switches as ignition source in potentially explosive atmospheres

Gases or dusts can be ignited by a spark discharge when DIP switches are used.

Switch off the power supply and wait until the 1-second UPS has discharged. Ensure that there is no explosive atmosphere before you use DIP switches.

Ten-pole DIP switch S101

The DIP switch has the following meaning for the Ethernet interfaces X101 and X102 which are switched:

DIP switch 1:

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 switch 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 switch 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 switch 1 to 8 set to ON	PN name via DIP switch 1 to 8 IP address and SNM via DHCP	PN name via DIP switch 1 to 8 IP address and SNM via DHCP
ON (1)	OFF (0)	reserved	-	-
ON (1)	ON (1)	PROFINET-compliant DIP switch 1 to 8 set to OFF	PN name from memory IP address from memory PROFINET name can be set via TwinCAT System Manager See chapter Get Station Name from Tree	PN name becomes empty string IP address 0.0.0.0
ON (1)	ON (1)	PROFINET with fixed name DIP switch 1 to 8 set to ON	PN name via DIP switch 1 to 8 IP address from memory PROFINET Name can be set via TwinCAT System Manager See chapter Generate Station Name from Control	PN name via DIP switch 1 to 8 IP address 0.0.0.0

	Setting the PROFINET name via DIP switch If the DIP switches 9 and 10 are set to ON up to GSDML version 2.3 the default name is build out of "cx8093-" and the setting of DIP switch 1 to 8. For this at minimum one of the DIP switches 1 to 8 has to 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 cx8093-3 If the DIP switches 9 and 10 are set to ON up to GSDML version 2.3 the default name is build out of "tcpniodevice-" and the setting of DIP switch 1 to 8. For this at minimum one of the DIP switches 1 to 8 has to be set to ON. Example - DIP 9 und 10 ON, - DIP 1 and 2: ON - DIP 3 to 8: OFF results in the PROFINET name tcpniodevice-3

Located under the flap between the battery and the SD card slot.
