Send Email 71
Send an Email with a
Controller-initiated
Message Instruction
A Logix controller can send a generic CIP message instruction to the
web server module that instructs the web server module to send an
email message to a SMTP mail server using the standard SMTP
protocol. This is useful to automatically communicate controller data
and/or application conditions to appropriate personnel.
Create String Tags
You need two controller-scoped string tags, one to contain the email
text and the other to contain the status of the email transmission.
These tags can contain as many as 474 characters.
You must create a user-defined STRING data type (the default STRING
data type in RSLogix 5000 software is not large enough for most email
text). For example, create a STRING data type named EmailString.
IMPORTANT
Be careful to write the ladder logic to ensure the MSG
instructions are not continuously triggered to send email
messages.
