Siemens S7-1200 MQTT

Anyone worked with the Siemens S7-1200 PLC with MQTT?

From the documentation it shows that it is a MQTT client, so it should be able to send and reduce data from an Ignition system with Cirrus Links MQTT modules right?

Yes, S7-1200 act as MQTT client which able to work with any Brocker

Since it’s not using SparkPlugB, the data come in won’t populate by default, there will need to be some custom configuration in the gateway right?

As I remember this lib only can publish data and not able to receive any data by subscribing. Also it is MQTT and not MQTT SB
