Description
The electronic mail notification service allows controller-based projects to report alarms or events. The controller monitors the system and dynamically creates an electronic mail message, which alerts local or remote users.
A user-defined event or condition triggers the MSTR block to create a message. Each message uses one of three user-defined headers. Each message sent from the controller can contain text and variable information (with a maximum of 238 bytes).
The project selects the appropriate header. Each header contains:
sender name
list of recipients
subject
To program an MBP_MSTR block to send email, use function code 13.
Network Implementation
A send email operation can be performed on a TCP/IP Ethernet network.
