QJ71E71-100 mail send

[gphong]

I used a translator.
Please understand.

Use the QJ71E71-100 card.
If the machine has an alarm, I would like to send it to the machine manager's Google email.

Is it possible?
Is there a reference program?

From a brief review of that module's documentation (User Manual SH(NA)-080010-P(1506)MEE), you cannot send directly from the PLC to any Google email.  Google, and many other email providers, do not accept email from random, unidentified devices on the internet.  If using a Google "From" address, you must use an SMTP submission port (465 or 587) and OAuth credentials.  Classic SMTP authentication will not be accepted (this was cut off last year).  If not using a Google "From" address, the sending machine must be identified as a valid sender for the domain name (via Sender Policy Framework) and must have DKIM or DMARC encrypted signatures attesting to its validity (tamper-proofing).

As shown in that manual's network diagram in §2.2, you are expected to have a proper email server in the facility with the PLC, and that server would be responsible for passing on the email with the appropriate modern security procedures.  If you have such a server, then simply configure the card to point at it, and use the MSEND instruction in your ladder program to trigger a new email.
