E-Mail Messages (Node 50 to 99) 6-3
Destination Addresses
The ENI stores e-mail addresses; it does not store the e-mail 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 e-mail ASCII text string address, as
illustrated in ST15:0 through ST15:5 in the example below.
Message Text
To send the actual e-mail 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
e-mail address (150 to 199).
The following table shows the relationship between the e-mail
message and the e-mail address. The maximum size of the message is
1 string element of 84 bytes.
IMPORTANT
Remember the following when setting up destination
addresses:
• The ENI can store up to 50 e-mail addresses.
• E-mail addresses can be up to 45 characters long,
exceeding this will result in an error.
• The e-mail address must contain an “@” character.
• E-mail addresses cannot contain any spaces or
any other special ASCII characters other than the
“@” character.
