Unfortunately, in my requirements, I failed to say that I also wanted to contact/interrogate the device via SMS/txt.
The TF6350 SMTP/SMS Solution appears to be only Outbound?
Unusual requirement, but sending messages to the PLC from your phone can be done, but just maybe in a different way. At least one way that I know of is to use the MQQT protocol via TF6701 TwinCAT 3 IoT Communication. From my understanding, there are MQQT phone apps that you can then use to send messages to the broker, which then get relayed to the PLC.
