Configuring the Email Service
(Original Document)
About us
Using the Email Service
Use the Simple Mail Transfer Protocol (SMTP) service to configure up to three (3) Email messages. The PLC uses the Email messages you configure to notify specified Email recipients about meaningful run-time events—for example, a change in the value of a variable, or a threshold overrun.
NOTE: The Email service is available only when you first perform the following tasks:
  • upgrade the firmware in the TSX ETC 101 Ethernet communication module to version 2.01 or higher
  • select the TSX ETC 101.2 Ethernet communication module for your project using Unity Pro version 7.0 or higher
NOTE: Unity Pro is the former name of Control Expert for version 13.1 or earlier.
Email messages are transmitted by the execution of a SEND_REQ function block included in your application logic.
NOTE: To successfully send an Email message using the SEND_REQ block, synchronize the SMTP service and PLC application—i.e., activate the SMTP service whenever the PLC is in RUN mode.
You can configure the Email service only in the Email Configuration page of Control Expert. You can diagnose the operation of the Email service in the diagnostic pages of both the Control Expertsoftware and the communication module web pages.
