Automatic Network Configuration TCP/IP Network Connectivity and ION Meters
Page 2 © 2007 Schneider Electric. All rights reserved.
Automatic Network Configuration
ION8800, ION8600, ION7550 and ION7650 Ethernet meters have several 
configurable parameters that are used in TCP/IP communications, such as IP 
address, default gateway, subnet mask, DNS server, etc. These parameters can be 
set manually (via the meter’s front panel, the meter’s Network Setup web page or 
ION software) or assigned automatically to the meters via a BootP server.
N
OTE
BootP is available for certain firmware versions only.
Some ION7550/ION7650 meters (firmware version 350 and later) also come pre‐
configured with IP addresses automatically assigned from the factory. The default 
IP address is 172.16.xxx.xxx, where the last two bytes of the address (decimal) 
match the last two bytes of the meter’s MAC address (hex). This ensures unique IP 
addresses. For example:
MAC address = 0060780112DC
12 (hex) = 18 (decimal) and DC (hex) = 220 (decimal)
Default IP address = 172.16.18.220
To learn how to configure meter network settings manually with the meter’s front 
panel, refer to your meter’s Installation Guide and your meter’s User Guide.
To learn how to configure meter network settings manually with the meter’s 
Network Setup web page, refer to the WebMeter Internal Web Server Feature 
technical note.
Using a BootP Server
BootP
 
(Bootstrap Protocol) is a protocol that automatically configures a device’s 
(e.g. meter) network settings without user involvement.
The BootP server is managed by your network administrator, who allocates the 
meter IP address and other network settings to the BootP server. When this is 
completed, and the meter is powered up, the BootP server automatically assigns 
the IP address and other network settings to the meter.
When the meter is in BootP mode, it does not require a manual re‐boot for an IP 
address change. Since most power meters cannot be easily re‐booted on demand, 
the meter is factory configured to poll the BootP server every eight hours for an IP 
address. If the IP address is changed on the BootP server, then the meter obtains 
the new address at the next polling interval.
Preparing the BootP Server to automatically configure network settings
1.Set up the BootP server on the same Ethernet network as the meter. Follow the 
documentation packaged with the BootP software for the correct installation.
2.Enter the meter’s Ethernet MAC address in the BootP database.

3.Allocate these settings to the meter Ethernet MAC address:
‹
meter IP Address
‹
Subnet Mask (if the network is subnetted)
‹
Default Gateway (if the network has a default gateway)
‹
SMTP Mail Server Address (if the meter will send email)
N
OTE
When the meter is in BootP mode, you must configure the network settings in the BootP server. Otherwise,
those settings are NOT updated on the meter. BootP mode prevents you from changing network settings
through the meter’s front panel, or via ION software.
Preparing the meter to use BootP
Depending on your meter and meter firmware version, BootP may be enabled by 
default. You can enable BootP with the meter’s front panel or with ION software. 
1.Set the IP Boot Option setup register in the Ethernet Comm module to BootP.
Domain Name Resolution (DNS) TCP/IP Network Connectivity and ION Meters
Page 4 © 2007 Schneider Electric. All rights reserved.
Domain Name Resolution (DNS)
A DNS (Domain Name System) server is used to resolve a domain name to a 
corresponding IP address. If a meter is configured to use a DNS server by 
specifying the IP address of the DNS server to the meter, then the meter can access 
other network resources (e.g. NTP and SMTP servers) by domain name rather than 
by IP address.
Preparing the meter to use DNS
Configure the following registers in the meter’s Ethernet Comm module:
Register Name Type Description Notes
Primary DNS Server String Setup
This register specifies the IP address of the primary
DNS server that the meter sends name queries to.
This value must be an IP address in the format
aaa.bbb.ccc.ddd.
‹
Domain name resolution is required if a
fully qualified domain name has been
entered for either the SMTP server
address or the NTP server address.
‹
Use the front panel, ION Setup, Designer
or a web browser.
Secondary DNS Server String Setup
This register specifies the IP address of the
secondary DNS server that the meter sends name
queries to.
This value must be an IP address in the format
aaa.bbb.ccc.ddd.
‹
Domain name resolution is required if a
fully qualified domain name has been
entered for either the SMTP server
address or the NTP server address.
‹
Use the front panel, ION Setup, Designer
or a web browser.
TCP/IP Network Connectivity and ION Meters Network Time Synchronization (NTP)
© 2007 Schneider Electric. All rights reserved.Page 5
Network Time Synchronization (NTP)
NTP (Network Time Protocol) is a protocol that synchronizes computer clock 
times in a network.
Preparing the meter to use NTP
Configure the following registers in the meter’s Clock module:
Configure the following registers in the meter’s Ethernet Communication module:
Register Name Type Description Notes
Enable NTP Time Sync Enumerated Setup
This register enables NTP time synchronization when
set to Yes, and disables it when set to No.
Default setting is No.
NTP Time Sync Interval Numeric Setup
This register specifies the frequency at which the
meter attempts to time synchronize via NTP. Values
between 60 seconds and 1 year are acceptable.
Default is 1 day (86,400 seconds).
Register Name Type Description Notes
NTP Server String Setup
Use this register to specify the IP address of the NTP
server that the meter synchronizes its clock to:
‹
This value can be either an IP address in the format
aaa.bbb.ccc.ddd or the fully qualified domain name of
an NTP server (for example, ntp.domainxyz.com).
‹
Maximum 80 alphanumeric characters, dot and dash
allowed.
‹
You cannot change this register using the
front panel (use ION Setup, Designer or
a web browser).
‹
If you enter a fully qualified domain
name for the NTP server you must also
specify a DNS server.
Email (SMTP) TCP/IP Network Connectivity and ION Meters
Page 6 © 2007 Schneider Electric. All rights reserved.
Email (SMTP)
SMTP (Simple Mail Transfer Protocol) is a TCP/IP protocol that sends and receives 
email. 
Preparing the SMTP Server
See the MeterM@il Internal Email Client Feature technical note for more information.
Preparing the meter to use SMTP
Configure the following registers in the meter’s Ethernet Comm module:
1
This register is only available on some meter models and firmwares. Check your meter’s technical
documentation for details.
Register Name Type Description Notes
SMTP Connection
Timeout
Numeric Setup
This defines the time period the meter will wait when
establishing a connection to an SMTP server:
‹
The default setting is 60 seconds, which is sufficient time if
the SMTP server resides on your local network.
‹
If the SMTP server is accessed using a dial-up connection,
you should increase the SMTP Connection Timeout value to
allow the meter sufficient time to establish the connection.
SMTP Server String Setup
This register specifies the IP address of the email server
that the meter sends outgoing email to:
‹
This value can be either an IP address in the format
aaa.bbb.ccc.ddd or the fully qualified domain name of an
SMTP server (for example, smtp.yourcompany.com).
‹
Maximum 80 alphanumeric characters, dot and dash
allowed.
‹
You cannot change this register using
the front panel (use ION Setup,
Designer or a web browser).
‹
If you enter a fully qualified domain
name for the SMTP server you must
also specify a DNS server.
SMTP Port Number
1
Numeric Setup
This register specifies the TCP/IP port the meter uses to
communicate with the SMTP server. Default is 25.
‹
You cannot change this register using
the front panel (use ION Setup,
Designer or a web browser).

Wide Area Network (WAN) Application (Modem)
The ION meter is located on a remote LAN, while the SMTP, NTP and DNS servers 
are on the Internet.
In this example, a dial‐on‐demand router is used to access the Internet (and the 
servers situated there) via telephone when required. Generally, the meter in this 
example would only access the Internet to send data (perform a “data push”).
