Parameterization and commissioning
CX8050, CX8051 - Embedded-PCs for
CANopen and CAN
35
Version: 1.4
2-pole DIP switch (under the flap between the battery and the SD card slot)
Requirements
DIP switch (red)
Meaning
1 off and 2 off
normal mode, TwinCAT is started
1 on and 2 off
The CX mode starts in Config Mode; the flash
memory or, in the case of the CX80xx the SD card, is
reachable via the USB interface (for example for an
image update).
1 off and 2 on
Restore the registry
1 on and 2 on
No function so far
6.2
Setting the IP adress
6.2.1
IP address
The CX8010, CX803x, CX805x and CX8080 have an Ethernet interface, X001.
X001
IP addressing via the operating system; default is DHCP (represented in the operating system as FEC1)
EtherCAT interface
The EtherCAT interface is a further Ethernet interface that is not visible in the operating system for the IP
addressing.
6.2.2
Setting the address via DHCP server
Port 1 (X001) is set to DHCP by default.
If DHCP is switched on, the CX is automatically assigned an IP address by the DHCP server. The DHCP
server must know the MAC ID of the Bus Terminal Controller for this. The IP address should be assigned
statically by the DHCP server. A local IP address is used if no DHCP server is reachable.
The DNS name is formed from the type and the last 3 byte of the MAC ID. The MAC ID is given on the
production label of the Bus Terminal Controller.
Example: CX80xx
• MAC ID: 00-01-05-01-02-03
• DNS name: CX-010203
6.2.3
Subnet mask
The subnet mask is subject to the control of the network administrator, and specifies the structure of the
subnet.
Small networks without a router do not require a subnet mask. The same is true if you do not use registered
IP numbers. A subnet mask can be used to subdivide the network with the aid of the mask instead of using a
large number of network numbers.
The subnet mask is a 32-bit number:
• Ones in the mask indicate the subnet part of an address space.
• Zeros indicate that part of the address space which is available for the host IDs.
