ND30-09D 44 User's manual
Modbus TCP/IP. Configure Ethernet group parameters to use the meter's
network services. The standard Ethernet parameters of the meter are shown
in Table 9. The main parameter is the IP address of the meter, e.g.
10.0.1.161, which must be unique in a network the device will be connected
to. The IP address can be assigned to the meter automatically by the DHCP
server present in the network if the meter has an option to obtain an address
from DHCP server enabled: Ethernet → Addresses → DHCP→ On If the
DHCP service is disabled then the meter will work with the default IP
address allowing the user to change the IP address, e.g. from the menu of
the meter. Change of the Ethernet parameters can also be done via the
RS485 interface. So it is required to confirm the changes by writing the
value "1" to the register 4149. The Ethernet interface is rebooted in
accordance with the new parameters after applying changes - all services of
the Ethernet interface are restarted.
10.3.1 Connecting 10/100-BASE-T interface
Connect the device to a TCP/IP network using the RJ45 socket
located at the back / terminal side / of the meter to get access to the
Ethernet services.
The meter's RJ45 socket LEDs description:
• yellow LED - illuminates when the meter is properly connected to the
Ethernet 100 Base-T, does not illuminate when the meter is not
connected to a network or is connected to a 10-Base-T.
• green LED - Tx/Rx, illuminates (irregularly illuminates) when the meter
sends and receives data, illuminates continuously when no data is
transmitted
It is recommended to use a twisted pair cable to connect the meter to the
network:
• U/FTP – twisted pair cable with a separate foil for every pair
• F/FTP – twisted pair cable with separate foil for every pair and
additional foil shielding for the cable
• S/FTP (former SFTP) – twisted pair cable with separate foil for every
pair and additional mesh cable shielding
• SF/FTP (former S-STP) – twisted pair cable with separate foil for
every pair and additional mesh and foil cable shielding
