EMail Messages (Node 50 to 99) 6-3
Destination Addresses
The ENI/ENIW stores email addresses; it does not store the email
messages. To store a destination address, write a message to a specific
node number (nodes 150 to 199). The message data must be a string
element that contains a valid email ASCII text string address, as
illustrated in ST15:2 through ST15:5 in the example below.
Message Text
To send the actual email message, the controller generates a write
message, with a string element as the data (see ST15:7 to ST15:9 in the
example above) to a node number (50 to 99) that correlates to the
email address (150 to 199).
IMPORTANT
Remember the following when setting up destination
addresses:
• The ENI/ENIW can store up to 50 email
addresses.
• Email addresses can be up to 45 characters long;
exceeding this will result in an error.
• The email address must contain an “@” character.
• Email addresses cannot contain any spaces or any
other special ASCII characters other than the “@”
character.
