Configuring advanced Ethernet parameters using the webpages
You can configure advanced Ethernet parameters, such as TCP keepalive, connection timeouts and idle times, using the Advanced Ethernet Settings webpage.
- Login to the meter webpages.
- Based on your meter firmware version, click OR click .
- Modify the Ethernet setup parameters as required.
-
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.

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

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

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

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
Used for data transfer.
Connection Security Mode
No Encryption, TLS/SSL Implicit Encryption
Encryption for secure mode connection.
Encrypted Control Port
1-65534
Establishes encrypted connection between hosts.
Encrypted Data Port
1-65534
Used for encrypted data transfer.
