Setting The Ip Address Using The Beckhoff Bootp Server - Beckhoff BC9000 Documentation

Parameterization and Commissioning
A short flash from the ERROR LED at the moment of switching on indicates that the Bus Coupler is being
addressed by ARP, and that DIP switches 1-8 give no indication of the address that is set.
Changing the IP address
If the IP address is changed, all dynamic ARP entries must be deleted. Only one ping with a length
of 123 bytes is permitted for the reconfiguration of the IP address (>ping -l "IP-Address<).
Sample
1. C:>ping 172.16.17.255
2. C:>ARP -a
172.16.17.255 00-01-05-00-11-22
3. C:>arp -d 172.16.17.255
4. C:>arp -s 172.16.44.44 00-01-05-00-11-22
5. C:>ping -l 123 172.16.44.44

Setting the IP Address Using the Beckhoff BootP Server

If the address is to be set by the Beckhoff BootP server, then set DIP switch 9 to ON (1) and DIP switch 10
to OFF (0). DIP switches 1-8 then no longer have any address function. If this is not the case, the Bus
Coupler reports LED error code 6-4 (see diagnostics LEDs). The TCP/IP ERROR LED flashes while the
address is being allocated.
IP address save modes
DIP switches 1-8 in the ON position
The address assigned by the BootP server is stored, and the BootP service will not be restarted after the
next cold start.
The address can be cleared again by reactivating the manufacturers' settings (using the KS2000 software or
by DIP switch and end terminal [} 22]).
DIP switches 1-8 in the OFF position
The IP address assigned by the BootP server is only valid until the Bus Coupler is switched off. The BootP
server must assign a new IP address to the Bus Coupler at the next cold start.
The address is, however, retained through a software reset of the Bus Coupler.
