Network Services
4.1.5.1 DHCP Client
The controller can get network parameters from an external DHCP master via the
DHCP Client service.
The following parameters can be obtained:
•
IP address
•
SubNet mask
•
Router/gateway
•
Hostname
•
Domain
•
DNS server
•
NTP server
For the IP address, SubNet mask and router/gateway parameters, the entries are
stored per ETHERNET port (X1, X2).
The Hostname and Domain parameters are stored according to the LIFO
principle (Last In First Out). The settings from the last DHCP offer received are
always used.
The DNS and NTP Server parameters are stored centrally for global use. All
transmitted parameters are saved.
4.1.5.2 DHCP Server
The controller provides the DHCP server service for the automatic configuration
of IP addresses of network stations on the same subnet.
Generally, only one DHCP server can be active on a subnet at one time.
The following can be set for the DHCP server:
•
The service itself (active/not active)
•
The range of dynamically assigned IP addresses
•
The lease time of the dynamically assigned IP addresses
•
A list with static assignments of IP addresses to MAC addresses
In “switched” mode, these settings are possible for both interfaces together and
in “separated” mode for each interface separately.
