TMAIL_C (Send an email using the Ethernet interface of the CPU) instruction
Overview
You use the "TMAIL_C" instruction to send an e-mail using the Ethernet interface of the S7-
1200 CPU.
The TMAIL_C instruction has two functionalities:
● Email over the CPU Interface (only SMTP without SSL)
● Email over a CP Interface (either SMTP without SSL or SMTP with SSL) If you want to
use the SSL functionality, you must set the TMAIL_C input parameter CERTINDEX = 1
and use the CP Interface. Also, the correct certificate must be stored in CP cert storage.
The instruction can only be used once the hardware has been configured and if the network
infrastructure allows for a communication connection to the mail server.
