EMail Messages (Node 50 to 99)
This chapter describes using the ENI/ENIW’s email feature. The
following topics are included:
• Overview
• Configuring Email
• Sending an Email Message
Overview The ENI/ENIW is capable of transmitting email messages generated by
the attached controller. This provides an extremely versatile
mechanism to report alarms, status, and other data-related functions.
To send an email message, the controller generates a 485CIF/PLC2
write message, with a string element as the data, to a node number
that correlates to the email destination address.
ENI/ENIW email behavior in a system is described by the following
diagram.
IMPORTANT
Email messages can only be initiated by controllers
that support String elements. Therefore, this
functionality cannot be used with the
MicroLogix 1000 family of controllers.
