Configuring the network
17.2 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 elap‐
ses, the server itself becomes the active server.
This additional pause makes it possible for the in‐
tended 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 require‐
ments of the RFC:
● ASCII letters (a-z, A-Z), digits (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 con‐
flicts 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 ER‐
TEC 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 to‐
gether. 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 by 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 by an
SNMP client. This is for information purposes only.
