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.

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.

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.
