4.3 Operation modes
4.3.1 Unicast
The movement has a network connection and is synchronized to UTC (Universal Time Coordinated)
from a NTP server. It is able to control up to three cascaded slave movements over the I
2
C bus (syn-
chronize, power and supervise).
This operating mode supports the monitoring and configuration of the movement via the network con-
nection. Network parameters can be automatically obtained from a DHCP server or can be manually
configured by means of the PC tool MOBA-NMS.
For supervision and configuration with MOBA-NMS one of the group addresses (multicast IP address-
es) 239.192.54.0 or 239.251.34.0 for IPv4 resp. FF38::EFC0:3600 or FF38::EFFB:2200 for IPv6 or the
IP address (selection with switch 2.7) is used.
The following switch settings select the operating mode Unicast (switches 1.5 to 1.8 and switch 2.8 in
OFF position):
Switch group 1:
ON
1 2 3 4 5 6 7 8
Switch group 2:
ON
1 2 3 4 5 6 7 8
In this operating mode the movement will attempt to obtain the following network parameters from a
DHCP server (see chapter 5.2):
-
IP address
-
Gateway address
-
Subnet mask
-
NTP server address(es) / Time zone server address
-
SNMP manager address
In this operating mode, the clock will try to obtain the following network parameters in an IPv6 network
from a DHCPv6 server (see also chapter 7.4):
-
IP address
-
NTP server address(es) / time zone server address
-
SNMP manager address
The NTP server addresses must be configured by the network administrator as DHCP options on the
DHCP server. If a server address was provided to the movement it will request time and time zone
packets (switch 1.4 in ON position) from this server. The request interval can be configured with the
PC tool MOBA-NMS.
4.3.2 Multicast
The movement has a network connection and is synchronized to UTC (Universal Time Coordinated)
from a NTP server. It is able to control up to three cascaded slave movements over the I
2
C bus (syn-
chronize, power and supervise).
Configuration can completely be done by means of the DIP switches on the movement (minimal con-
figuration effort). Further this mode supports monitoring of the movement via the network connection.
Single configuration parameters can be changed with MOBA-NMS via network.
For supervision and configuration with MOBA-NMS one of the group addresses (multicast IP address-
es) 239.192.54.0 or 239.251.34.0 is used (selection with switch 2.7). The group address is an IP ad-
dress in the multicast range (224.0.0.0 to 239.255.255.255), addresses selected by Moser-Baer AG
from a freely available range:
-IPv4: 239.192.54.x and 239.251.34.x, whereat x = 1..15
