6-4 EMail Messages (Node 50 to 99)
Message Fields (to, from, subject)
The ENI/ENIW includes the “to”, “from”, and “subject” fields in the
body of the message.
The default “from” text is [email protected]
([email protected] for series D). This can be changed in
the ENI/ENIW configuration, Node 249. See page 6-2 or Chapter 4.
The standard format of the “subject” line is:
Subject: 1761ENI.MSG(plus the first 32 characters of text)
For example, if the message text was “The quick brown fox jumped
over the lazy dog’s back”, the “subject” line would read:
Subject 1761ENI.MSG(The quick brown fox jumped over)
Sending an Email Message
The ENI/ENIW uses a pair of node addresses to send email or data
messages over TCP/IP. To send email, two sets of addresses are used
as illustrated in the table below. Node numbers 150 to 199 are used to
define or store the actual email address, and nodes 50 to 99 are used
to send the string element to the email recipient. The maximum size
of the message is 1 string element of 82 bytes.
