E-MAIL: CONFIGURATION AND OPERATION
Overview
The HI 3000 Series instruments are configured with E-mail
capability (SMTP Sender) that enables the user to send either
Basic Alarm E-mails or Custom Event E-mails to remote
locations on a local network, wide area network or the Inter-
net. The E-mail capability allows the user to maintain a sys-
tem update automatically listing any alarm conditions or
events that occur in the weigh process or condition monitor-
ing system. It provides an alternative to networked audio or
video alarms which cannot be detected when personnel are
away from the process or control room itself or outside of the
plant. In addition you can configure the filters in your
browser to collect certain E-mails for a certain category.
NOTE: The HI 3000 Series Instruments cannot receive
E-mail messages.
The Standard Format E-mail allows the user to specify up to
3 groups of E-mail addresses where alarms can be sent. The
3 groups of E-mail addresses can list as many as can fit in a
240 character address field per group. For example:
• [email protected], rob-
[email protected], sally-
[email protected]
- will yield fewer group addresses.
• [email protected], [email protected],
[email protected] - will yield far more group
addresses.
In addition to each E-mail address, the user can select which
events/alarms are forwarded by selecting the setpoints (1-12)
from a list which sends a predefined formatted E-mail to the
list of E-mail addresses in the group. There is no limit as to
how many events/alarms can be forwarded to an E-mail
address.
The Custom Format E-mail is configured using the Custom
Event E-mail Setup web page and the Mapping Web Page.
The Custom Event E-mail allows the user to define the Des-
tination, Subject and Body of the E-mail. In addition to the
three main parts of an E-mail the user can define which
events trigger the E-mail. This is accomplished by defining
the events through the use of tokens (< >) in the body of the
E-mail. To illustrate:
Body = <2C0><50><HO0.0>
<2C0> is the parameter for Gross Weight on Channel 1 and
is replaced by the words - “Gross Weight”
<50> is replaced by the current date and time.
<HO0.0> is replaced by a floating point integer reflecting
the actual Gross Weight - 100.000
All configuration procedures must be performed from the
web-browser. The DNS server address can be entered from
the front panel of any HI 3000 Series Instrument.
Understanding IP Addresses
An IP address consists of four octets (1 octet = 8 bits), or 32
bits. The value in each octet ranges from 0 to 255 decimal, or
00000000 - 11111111 binary.
These octets are broken down to provide an addressing
scheme that can accommodate large and small networks.
There are five different classes of networks, A to E. Here,
we'll only be addressing classes A to C, since classes D and
E are reserved. To determine the class of an address, look at
the first octet of the dotted-decimal address.
Class A: 1 - 126 (e.g. 10 .1.23.19)
Class B: 128-191 (e.g. 172.16 .19.48)
Class C: 192-223 (e.g. 193.18.9 .10)
In a class A address, the first octet is the network portion, so
the class A example above has a major network address of
10 . Octets 2, 3, and 4 (the next 24 bits) are for the network
manager to divide into subnets and hosts as she/he sees fit.
Class A addresses are used for networks that have more than
65,536 hosts (actually, up to 16,581,375 hosts!).
In a class B address, the first two octets are the network por-
tion, so the class B example above has a major network
address of
172.16 . Octets 3 and 4 (16 bits) are for local sub-
nets and hosts. Class B addresses are used for networks that
have between 256 and 65,536 hosts.
In a class C address, the first three octets are the network
portion. The class C example above has a major network
address of
193.18.9. Octet 4 (8 bits) is for local subnets and
hosts - perfect for networks with less than 256 hosts.
Glossary of E-Mail Terms
Gateway
A node on a network that serves as an entrance to another
network. In enterprises, the gateway is the computer that
routes the traffic from a workstation to the outside network
that is serving the Web pages. In homes, the gateway is the
ISP that connects the user to the internet.
