4.5.9.7 EtherNet/IP address switching positions
Switch position
Description
0x00
The IP address saved in flash memory is used. The adapter is started via DHCP if attribute 3 (configuration control) of
the TCP/IP interface object was set to DHCP.
0x01 to 0x7F
The last position of the IP address saved in flash memory is changed to the address switch value. The IP address saved
in the flash memory is not changed. All other adapter parameters are read from the flash memory and are used without
being changed.
0x80 to 0xEF
The bus controller runs in this range in DHCP mode. The DNS server is informed of the current host name. A host name
is generated according to the setting of the network address switch.
The generated host name is made up of three elements:
"br" + "eip" + address switch number (three decimal places)
Example:
This means that a address switch number of e.g. 0xD7 (dec. 215) would result in the following host name:
"breip215"
0xF0 to 0xFD
Reserved (same function as position 0xFF).
0xFE
All bus controller parameters are initialized with default values during the boot procedure. No values are read from the
flash. The communication parameters are equal to the values as with the switch setting 0xFF.
0xFF
All communication parameters are initialized with default values. All other bus controller parameters are read from the
flash.
The default parameters:
•
IP address:
192,168,100.1
•
Network mask:
255,255,255.0
•
Gateway:
192,168,100,254
•
Primary NetBIOS name:
"br" + MAC address
•
Secondary NetBIOS name:
"br" + "eip" + address switch number (decimal)
•
X2X Link configuration:
1 ms cycle time
•
X2X Link cable length:
0 m
Table 155: Network address switches
4.5.9.8 Setting the IP address (default value)
Changes to the network address switch are only applied after a restart (power cycle). If the bus controller is restarted
with the address switch number 0xFF, it is initialized with the IP address 192.168.100.1. This address is also the
default address upon delivery.
This IP can be used to establish a connection to the bus controller. The internationally unique MAC address is
listed on the housing side of the bus controller. The combination of "br" and the MAC address results in a unique
name (primary NetBIOS name) that also makes it possible to access the bus controller.
Example for the primary NetBIOS names:
MAC address:
00-60-65-00-49-02
Resulting NetBIOS name:
br006065004902
This means that, without additional parameter changes, either the default IP address 192.168.100.1 or the NetBIOS
name "br+MAC" can be used to communicate with the controller.
The bus controller can only be accessed via this name if there are no intermediary routers or gateways because
the NetBIOS method is used.
