Ethernet port configuration page

The
Ethernet
 configuration page is available for L20E, L50E, and L70E controllers. Use the page to do the following actions:
  • View and configure the port and IP address settings for IPv4 or IPv6 (for L50E and L70E controllers only).
  • Obtain IP addresses automatically using Dynamic Host Configuration Protocol (DHCP) or manually configure IP settings, and then download it to the controller when in
    Program
     mode.
  • Open the communication diagnostics view.
  • Synchronize the settings in the controller with the
    Internet Protocol Settings
     in your project using the
    Download to controller
     or
    Upload from controller
     button.
  • Select and clear the
    Detect duplicate IPv4/IPv6 address
     checkbox to enable and disable duplicate IP address detection.
  • Turn on or turn off duplicate IP address detection for IPv4 or IPv6 (for L50E and L70E controllers only).
  • Configure port settings, such as mode and speed.
    If you change the
    Speed
     or
    Duplex Mode
     settings and then download changes to the controller,
    FactoryTalk Design Workbench
     disconnects the controller after the download. This only happens when using an Ethernet connection, not when using a USB connection.
  • Enable or disable the
    Modbus TCP
     server.

    , such as IP addresses from 169.254.0.0 through 169.254.255.255
  • IP addresses from 224.0.0.0 through 255.255.255.255
When you configure the IP address manually, the box displays either of the following:
  • The IP address in the controller, when the controller is online and its settings align with the specified IP address parameter value
  • The entered IP address
Subnet mask
Separates the entered IP address into a network address and a host address.
  • When you use the DHCP server to obtain network addresses, the subnet mask is displayed when the controller is connected.
  • When configuring the network settings manually, you must enter the IP address, and then select the
    Subnet mask
     box to fill the value automatically.
If the subnet mask is not correct, you cannot build the program successfully.
Gateway address
Specifies the network address of the gateway that connects individual physical networks into a system of networks.
  • When you use the DHCP server to obtain network addresses, the gateway address is displayed when the controller is connected.
  • When configuring the network settings manually, you must enter the gateway address.

IPv6 address
, Subnet prefix length, and Gateway address.
Available when IPv6 is enabled.
Options are:
  • Enabled
  • Disabled
It is disabled by default.
IPv6 address (for L50E and L70E controllers only)
Identifies the IPv6 address for the controller on an EtherNet network.
IPv6 address is 128 bits long, represented as eight groups of four hexadecimal digits, separated by colons. For example, 2001:0db8:0000:0000:0000:0000:0000:0001.
The following IPv6 addresses are likely to be set to the
Micro800
 controller:
  • The IP address you entered, which is one of the IPv6 addresses set for the controller.
  • The read-only IPv6 address set by the router. It shows the last known value. The address is always available, and it appears dimmed when the controller is offline.
  • The read-only IPv6 address set by the static or DHCP server. It shows the last known value. The address is always available, and it appears dimmed when the controller is offline.
  • The read-only Linked Local Address set by the firmware using the SLAAC (Stateless Address Autoconfiguration) method. It shows the last known value and is always available.
Subnet prefix length (for L50E and L70E controllers only)
Specifies the size of the network portion of the IPv6 address.
The valid subnet prefix length range is from 0 through 128.
For example, an IPv6 address 2001:0db8:85a3:0000:0000:8a2e:0370:7334 with a subnet prefix length of 64 means that the first 64 bits (2001:0db8:85a3:0000) identify the network portion, and the remaining 64 bits identify the host portion.
When configuring the network settings manually, enter the
IPv6 address
, and then click the
Subnet prefix length
 box to auto fill the value. Otherwise,
Subnet prefix length
 remains empty.
Gateway address (for L50E and L70E controllers only)
A gateway connects individual physical networks into a system of networks.
When configuring the network settings manually, enter the
IPv6 gateway address.
Detect duplicate IPv6 addresses (for L50E and L70E controllers only)
Enables and disables duplicate IPv6 address detection.
  • Enabled
  • Disabled
It is enabled by default.

The maximum number of client IP addresses for access control is 5.
End point type
Selects the endpoint type from one of the following:
  • Listening
    : Supports using a single TCP connection as a server, through which unsolicited responses can exclusively be transmitted. The connection is established by the DNP3 client. User Datagram Protocol (UDP) broadcasts are accepted.
    Listening
     is the default value.
  • Dual
    : Supports using single TCP connections as a server and a client. When a TCP server connection is not present, unsolicited responses are sent to the DNP3 client via the TCP client connection. UDP broadcasts are accepted.
  • Datagram only
    : DNP3 over Ethernet communication is exclusively accomplished via UDP. TCP connections are not supported.
Local port number (UDP)
Specifies the UDP port number on the controller that the DNP3 client uses for UDP broadcasts. This is used with any endpoint type.
The port number ranges from 0 through 65535. The default value is 20000.
Local port number (TCP)
Specifies the TCP port number on the controller that the DNP3 client connects to. This is used with a
Listening
 or
Dual
 endpoint.
The port number ranges from 0 through 65535. The default value is 20000.
Master UDP port number (Unsol)
Specifies the UDP port number on the DNP3 client to which the controller sends unsolicited responses. This is used with a
Datagram only
 endpoint.
The port number ranges from 0 through 65535.
Master UDP port number (Init Unsol)
Specifies the UDP port number on the DNP3 client to which the controller sends its unsolicited null response with RESTART IIN bit set after a restart.
This is used with a
Datagram only
 endpoint and
Send the initial unsolicited null response on restart
 is selected on the
DNP3 Slave
 tab.
The port number ranges from 0 through 65535.
Master TCP port number (Unsol)
Specifies the TCP port number on the DNP3 client to which the controller connects for unsolicited response.
This is used with a
Dual
 endpoint and when the DNP3 client doesn't already have a TCP connection open with the controller.
The port number ranges from 0 through 65535. The default value is 20000.
Keep-alive interval
Specifies the time interval, in seconds, for the TCP keep-alive mechanism. If the DNP3 client does not send any communication on an open TCP connection within this timeout period, the controller initiates a DNP3 Data Link Layer status request. If no response is received within the confirmation time period, 10 seconds by default, the controller will end the TCP connection.
This is used with a
Listening
 or
Dual
 endpoint.
The value is from 1 through 65535. The default value is 10.
