Manually Setting the IP Address
Automatically Assigning an IP Address using DHCP
Automatically Assigning an IP Address using Auto-IP
To set the IP address manually both the DHCP and Auto-IP must be disabled. The IP address, subnet mask and
gateway address will be set from the values in the parameters
0933 User IP Address, 0934 User Subnet Mask,
0935 User Gateway Address.
If the network does not have a gateway to another network then the gateway address may be set to 0.0.0.0
If the network on which the AC30 is connected has a DHCP (Dynamic Host Configuration Protocol) server then the
IP address may be assigned by this server. The DHCP must be enabled. The AC30 will then request an IP address,
subnet mask and gateway address from the DHCP server.
Note: The IP address is requested by the AC30 each time the drive is powered up or when the Ethernet cable is
plugged in. There is no guarantee that the DHCP server will provide the same IP address each time.
The AC30 may assign itself a link-local address automatically using Auto-IP. This would be used where an automat-
ic address is required but where no DHCP server is available, such as a small local network or when connecting an
AC30 drive directly to a PC (point to point). The Auto-IP must be enabled.
The AC30 will choose an IP address randomly from the link-local range
169.254.*.*
. The AC30 checks that no other
Ethernet device on the network is using the address before allocating it. The AC30 will store this IP address (in pa-
rameter
0931 Last Auto IP Address
) and attempt to use it next time Auto-IP is used. The gateway address is fixed
to 0.0.0.0

0932 DHCP to Auto IP
Timeout in seconds after which DHCP stops and Auto
IP address is assigned.
Using Both DHCP and Auto-IP
If both the DHCP and Auto-IP are enabled then an IP address will be obtained automatically depending on the net-
work. This is the default setting.
The AC30 will take a link-local address in the range 169.254.*.* if no DHCP server is discovered on the network. If
a DHCP server is available (or becomes subsequently available) then the AC30 will take the IP address from the
server. Note that the DHCP has precedence.
