it looks like it is, in principle, possible to have your S7-1200 PLC send emails directly, without needed a PC involved. For more info, see:
Whether these techniques will work well in your system largely depends on the amount of data to be sent and how specific your data format requirements are. I don't think the TMAIL_C instruction does attachments, so the data transmitted would have to be directly in the email message. If you are sending a lot of data, this may not be feasible. Mechanisms that I know of that support sending data as email attachments all involve some type of computer: not necessarily a full blown PC, but at least something like a IOT2040/2050 or an Edge device. In theory you could build up a full SMTP client using TSEND & TRCV, but that isn't anything I would want to tackle. Another possibility would be to use the LMQTT_Client blocks and send JSON-encoded data to a cloud-based MQTT broker. The larger cloud players (AWS, Azure, etc.) have mechanisms for directing MQTT data to other types of clients, so I would expect that there is some way to transform the MQTT data to the format you are looking for. |
