Configuring the network
16.2 Settings of the system network
Description
Specifies a maximum waiting time (in seconds)
for the response of the master server (see DHCP
server synchronization mode). After this time
elapses, the server itself becomes the active
server.
This additional pause makes it possible for the
intended DHCP master to become the active
DHCP server without displacement even if it is
shortly switched on thereafter, or takes longer to
boot than other controls.
Default: 120 seconds
Assigns the DHCP server a fixed host name. In
this way, the server can also be addressed via
the host name and not only via the IP address.
Because the host name is also used as DNS
name, it must satisfy the corresponding
requirements of the RFC:
ASCII letters (a-z, A-Z), numbers (0-9) and '-'
•
maximum 63 characters
•
This is used to specify the Top Level Domain
(TLD) name used in the system network. The
DNS server of the NCU assigns names to the
devices in the system network in this zone. Name
requests for all other zones are forwarded to an
external name server in the company network.
The "local" default setting recommended by the
RFC1035 is used for local networks, to avoid
conflicts with globally defined domain names. As
a rule, this default setting is sufficient.
A separate machine name can be defined here
for PROFINET purposes. This is used at the
ERTEC interface (when available), transferred to
the ERTEC system program and also used by
DCP at this network interface.
This string is used for the SINUMERIK-specific
OID mcSinumerikMIB.mcSinumerikMiscStation.
The value is the name of a station to which the
device belongs. Devices with the same station
name can therefore be identified as belonging
together. This is for information purposes only.
This string is used for the standard OID SNMPv2-
MIB::sysLocation. If required, a location can be
specified here which can be called with an SNMP
client. This is for information purposes only.
This string is used for the standard OID SNMPv2-
MIB::sysContact. If required, a contact address
can be specified here which can be called with an
SNMP client. This is for information purposes
only.
