1 Introduction
The optional Ethernet module enables the instrument to be
connected to computer networks for remote monitoring and
data access. The module contains an embedded web server
enabling the instrument's data and status to be viewed remotely
using an internet browser on a PC. The web server supports up
to eight independent connections.
1.1 Ethernet Communications
Ethernet is a form of electronic communication that has been
adopted as a worldwide networking standard. Each device on
an Ethernet acts independently from other stations on the
network, that has no central controller.
There are a number of media that can be used for Ethernet
interconnections, e.g. coaxial cable, unshielded twisted pair
(UTP) cables and air transmission. The Ethernet module fitted to
the instrument supports the 10BaseT standard that uses UTP
cable to connect nodes. UTP cable comprises four pairs of
wires twisted together into a single cable.
Ethernet signals are transmitted serially, one bit at a time, over a
shared signal channel to every station attached to the network.
When a station has data to transmit, it 'listens' to the channel to
wait until the channel is idle then transmits its data as an
Ethernet frame or packet. After each frame transmission all
stations must contend equally for the next frame transmission
opportunity. This ensures that no station can lock out the other
stations on the network.
Access to the network channel is determined by the Medium
Access Control (MAC) mechanism embedded in the Ethernet
interface of each station. This mechanism is based on a Carrier
Sense Multiple Access with Collision Detection (CSMA/CD)
system.
Each Ethernet frame contains the source and destination
addresses for the frame, a variable size data field and an
error-checking field that checks the integrity of the frame
content to ensure that it has been delivered intact. The address
fields, called physical or MAC addresses, are each 48-bits long.
Every station on the network has a unique, pre-assigned MAC
address programmed into its Ethernet Option board.
1.2 Higher Level Protocols
Data can be transmitted over an Ethernet network using higher
level protocols that overlay the Ethernet infrastructure. The
higher level protocol packets are contained within the data field
of Ethernet packets. The instrument uses the Transmission
Control Protocol/Internet Protocol (TCP/IP); this is a worldwide
standard that was used to create the Internet.
The Internet Protocol (IP) routes the packets of information to
their destination devices. The routing is performed using an IP
address embedded in the header attached to each packet. The
IP address is a 32-bit number divided into four sections (called
octets) that are shown as decimal values. A typical example is
192.168.1.1.
The Transmission Control Protocol (TCP) establishes a
connection between the two devices before any data is
transmitted; this enables confirmation of receipt of all
transmitted packets, so that any lost packets can be
re-transmitted.
Other protocols that operate at the same level are the Address
Resolution Protocol (ARP) and the Internet Control Message
Protocol (ICMP).
Above the TCP and IP layers there are a number of application
protocols that perform a range of tasks. Typical examples are
File Transfer Protocol (FTP) and HyperText Transfer Protocol
(HTTP).
These layers fit together to provide a full data transfer system:
FTP provides a reliable mechanism for the transfer of files
between a client and a server – see Fig. 1.1.
HTTP enables the transfer of hypertext files such as web pages
and allows a web browser to access pages within a web server
– see Fig. 1.2.

SM1000 only – from the 'System Configuration' screen, access
the Ethernet Module:
SM2000 only – from the 'System Configuration' screen, access
the Ethernet Module:
Set the IP-address to be assigned to the instrument. The IP
address is used by the TCP/IP protocol to distinguish between
different devices. The address is a 32 bit value expressed with
four values (0 to 255), each separated by a period (.).
The subnet mask is used to indicate which part of the IP
address is for the network ID and which is for the host ID. Set as
'1's each bit that is part of the network ID, e.g. 255.255.255.0
indicates first 24 bits are for the network ID.
Set the IP address for the 'Default gateway' (router, switch etc.)
required to communicate with other networks. This setting may
not be required. The default setting is '0.0.0.0'
The 'FTP User' name and password are used during logon to
enable the FTP server. Access for up to four different users is
provided. These passwords can also be used to allow access to
some functionality provided by the web server.
Enter the name of the user granted FTP access.
Enter the password of the user granted FTP access.
Select whether this FTP user has full access (i.e. the ability to
read, write and delete files) or read-only access.
Select the level of remote operation access granted to this user:
None – the user is unable to log on to the instrument
remotely using a web browser
Operator – the user can acknowledge alarms and
start/stop totalizers using a web browser
Configuration – in addition to operator functions, the user can
load configurations and change the
instrument's internal clock using a web
browser
Note. Changes to the IP address, subnet mask and default
gateway are implemented only after the instrument has
been restarted. Change the addressing parameters, exit
and save the configuration, wait until the 'Please Wait'
message disappears then power down and restart the
instrument.

3.2 Testing a Network Connection
With the instrument connected to an Ethernet network (see
Section 2, page 3) and configured for use (see Section 3.1,
page 5), use the MS-DOS® 'ping' command to test its
operation:
1. On the PC, click the 'Start' button on the task bar and
select 'Run'.
2. In the 'Open:' field, type 'cmd' then click the 'OK' button.
This displays a DOS window with the cursor at the default
drive prompt:
3. Type 'ping' followed by the IP address assigned to the
instrument and press Enter. A message is displayed in the
window indicating that a ping operation is sending 32
bytes of data to the specified address. If the connection
and address are correct, four replies are received, e.g.:
Pinging 192.168.1.1 with 32 bytes of data:
Reply from 192.168.1.1: bytes = 32 time<10ms TTL=128
Reply from 192.168.1.1: bytes = 32 time<10ms TTL=128
Reply from 192.168.1.1: bytes = 32 time<10ms TTL=128
Reply from 192.168.1.1: bytes = 32 time<10ms TTL=128
4. If a valid response is not received, check that the correct
IP address was entered and that the host PC has an IP
address with the same network ID as defined by the
subnet mask. If that is correct, check the connecting
cable and confirm that the green continuity LED on the
instrument's Ethernet module indicates that a connection
has been made – see Fig. 2.1.
3.3 Configuring FTP Access
The FTP server in the instrument is used to access its file system
from a remote station on the network. This requires an FTP client
on the host PC. Both MS-DOS® and Microsoft® Internet
Explorer version 5.5 or later can be used as an FTP client.
A File Transfer Scheduler Program (FTSP) is available that
enables archive and configuration files to be transferred
automatically to a PC using FTP. The transferred files can be
stored either on the local drive of the PC or on a network drive
for easy access and secure back-up.
To obtain the FTSP (FTS.exe), enter the following (without
spaces) in a web browser's address bar:

3.5 E-Mail
The instrument can be configured to send e-mails to a
maximum of 6 recipients in response to certain events. The
addressees can all subscribe to the same SMTP server or the
instrument can be configured to send e-mails via 2 different
SMTP servers to a maximum of 3 addressees per server.
Up to 10 independently configurable triggers may be enabled to
generate an e-mail when the selected source becomes active.
When a trigger source becomes active, an internal 1 minute
delay timer is started. At the end of that minute, an e-mail is
generated that includes, not only the event that initiated the
delay timer, but every other event that occurred during the delay
period together with any enabled reports. The data returned in
the e-mail therefore reflects the real-time alarm state at the time
the e-mail was generated, not the state when the first trigger
source became active.
Each e-mail includes a link to the instrument's embedded web
server enabling the instrument's data and status to be viewed
remotely using an internet browser on a PC – see Section 5,
page 17.
3.5.1 Configuring the Instrument
Enter the IP address of the SMTP server through which e-mails
are to be routed.
Enter the address(es) of the e-mail recipient(s).
Select the options to enable.
Channels Report
When selected, a summary of all enabled channels together
with their instantaneous values is included in the e-mail.
Totalizers Report
When selected, a summary of all enabled totalizers together
with their instantaneous values is included in the e-mail.
External Media Report
When selected, a summary of the condition of the external
media (if any) and archiving status is included in the e-mail.
Fig. 3.6 is an example of a reports e-mail.
Select up to 10 event source types to generate an e-mail.
Fig. 3.7 is an example of an event triggered e-mail.
Note.
Reports, when enabled, are included only on an
e-mail generated as a result of a real time alarm event
unless the 'Reports in ALL emails' box is ticked, in
which case enabled reports are included on every
e-mail generated.
Triggers 6 to 10, if enabled (see below), may be
'inverted', i.e. an e-mail is generated when the trigger
source becomes inactive instead of active. Event
trigger source types that cannot be inverted are:
Alarm acknowledge, Any alarm and New alarm.

4.1 Introduction
Modbus TCP enables Modbus TCP devices to communicate via an ethernet network transferring Modbus messages via TCP/IP.
Communication with standard, serially connected, Modbus RTU devices is also possible through a Modbus TCP Gateway.
The instrument can be configured to act as either a Modbus TCP Server (Slave) or a Modbus TCP Client (Master) device on a
Modbus TCP network.
If configured as a Server, the recorder responds to Modbus queries transferred via the Modbus TCP protocol for the registers
described in Appendix B of the relevant instrument’s User Guide, IM/SM1000 or IM/SM2000. The recorder can be configured for
unrestricted access or access can be restricted to a maximum of 6 Modbus TCP Clients, from defined IP addresses.
If configured as a Client, the recorder collects data from Modbus TCP Servers (or RTUs via a gateway) into its 24 Comms Analog and
24 Comms Digital Channels. Each analog and digital input can be individually configured to any register within any slave device. The
configuration allows for receipt of data in most commonly used data formats
