Communicating with Devices on an EtherNet/IP Link 6-23
Using a MSG Instruction to
Send an Email The controller is an email client that uses a mail relay server to send email.
The DriveLogix5730 controller can execute a generic CIP message that
sends an email message to an SMTP mail relay server using the standard
SMTP protocol.
Some mail relay servers require a domain name be provided during the
initial handshake of the SMTP session. For these mail relay servers, make
sure you specify a domain name when you configure the network settings.
See 6-3 for information on configuring the network settings of the controller
and specifying a domain name.
Important: Be careful to write the ladder logic to ensure the MSG
instructions are not continuously triggered to send email
messages.
Creating String Type for Email String Data Type
The tags for the email text and transmission status can contain as many as
474 characters. For these tags, you must create a user-defined STRING data
type that is larger than the default. For example, create a STRING data type
named EMAILSTRING.
1. While offline, in the Controller Organizer, right click on the folder for Strings and select New String Type.
2. Enter the Name (e.g. EMAILSTRING) and the maximum number of
characters (e.g. 520).
Click Apply, then OK.
