Configuring advanced Ethernet parameters using the webpages

NOTE: Refer to Restoration of temporarily disabled configuration settings in webpages to know availability of these features on your meter model.

You can configure advanced Ethernet parameters, such as TCP keepalive, connection timeouts and idle times, using the Advanced Ethernet Settings webpage.

  1. Login to the meter webpages.
  2. Based on your meter firmware version, click Settings > Advanced Ethernet Settings OR click Settings > Communication > Advanced Ethernet Settings.
  3. Modify the Ethernet setup parameters as required.
  4. Click Save changes or Apply Changes to send and save the new settings to the meter.
    NOTE: Click Default to reset the advanced Ethernet parameters to their default values.

    Refer to the table below for the following firmware versions:

    • PM5560 / PM5562 / PM5563 / PM5580 meter models: 2.9.9 and earlier

    • PM5570 / PM5660 / PM5760 meter models: 3.2.9 and earlier

    • PM5650 meter model: 2.12.9 and earlier

    • PM5561 meter model: 10.9.9 and earlier

    • PM5661 / PM5761 meter models: 11.2.9 and earlier

    Parameter Values Description

    Time to Live

    1-255

    The maximum number of hops (in other words, devices such as routers) that a TCP packet is allowed to pass through before it is discarded

    TCP Keep Alive

    0-65000

    How frequently (in seconds) the meter sends a TCP keepalive packet.

    A setting of 0 disables the sending of TCP keepalive packets.

    BootP Timeout

    0-60

    The length of time (in seconds) that the meter waits for a response from a BootP server (the default IP address is used after timeout if no IP address is assigned.)

    ARP Cache Timeout

    0-65000

    The length of time (in minutes) that ARP entries are kept in the ARP cache

    FTP Server

    Enabled, Disabled

    Enables or disables the meter’s internal FTP server

    FTP Connection Idle Time

    30-900

    The length of time (in seconds) after which an idle FTP connection is closed

    HTTP Connection Idle Time

    0-65000

    The length of time (in seconds) after which an idle HTTP connection is closed

    HTTP Port Number

    80, 1024- 65000

    The TCP port used for HTTP messages. The following port numbers are reserved for other network protocols and cannot be used: 20 / 21 (FTP), 161 / 162 (SNMP) and 502 (Modbus TCP/IP).

    HTTP Maximum Keepalives

    0-65000

    The number of times the meter sends a keepalive signal if it does not receive a response

    Modbus TCP/IP Server Connections

    16, 32, 36, 40, 44, 48, 64

    The number of TCP connections used for Modbus TCP communications when the meter is functioning as an Ethernet gateway

    Modbus TCP/IP Server Connection Idle Time

    0-32767

    The length of time the meter waits for a Modbus TCP/IP device to respond to a connection request initiated by the meter.

    Refer to the table below for the following firmware versions:

    • PM5560 / PM5562 / PM5563 / PM5580 meter models: 4.0.0 and above

    • PM5570 / PM5660 / PM5760 meter models: 6.0.0 and above

    • PM5650 meter model: 4.10.0 and above

    • PM5561 meter model: 12.0.0 and above

    • PM5661 / PM5761 meter models: 14.0.0 and above

    Parameter Values Description

    Time to Live

    1-255

    The maximum number of hops (in other words, devices such as routers) that a TCP packet is allowed to pass through before it is discarded.

    TCP Keep Alive

    0-65000

    How frequently (in seconds) the meter sends a TCP keepalive packet.

    A setting of 0 disables the sending of TCP keepalive packets.

    BootP Timeout

    0-60

    The length of time (in seconds) that the meter waits for a response from a BootP server (the default IP address is used after timeout if no IP address is assigned.).

    ARP Cache Timeout

    0-65000

    The length of time (in minutes) that ARP entries are kept in the ARP cache.

    Enable HTTPS

    By default the HTTPS is always enabled.

    Hypertext Transfer Protocol Secure (HTTPS): HTTPS is a variant of the standard web transfer protocol (HTTP) that adds a layer of security on the data in transit through a Secure Socket Layer (SSL) or Transport Layer Security (TLS) protocol connection. HTTPS enables encrypted communication and secure connection between a remote user and the meter.

    HTTPS Port

    443, 1024- 65000

    The TCP port used for HTTPS messages. The following port numbers are reserved for other network protocols and cannot be used: 20 / 21 (FTP), 161 / 162 (SNMP) and 502 (Modbus TCP/IP).

    Modbus TCP/IP Server Connections

    16, 32, 36, 40, 44, 48, 64

    The number of TCP connections used for Modbus TCP communications when the meter is functioning as an Ethernet gateway.

    Modbus TCP/IP Server Connection Idle Time

    0-32767

    The length of time the meter waits for a Modbus TCP/IP device to respond to a connection request initiated by the meter.

    FTP

    Enabled, Disabled

    Enables or disables the meter’s internal FTP server.

    Control Port

    1-65534

    Establishes connection between hosts.

    Data Port

    1-65534

    Encrypted Control Port

    1-65534

    Establishes encrypted connection between hosts.

    Encrypted Data Port

    1-65534

    Used for encrypted data transfer.
