MQTT driver: Can it subscribe? Or only publish?

[drmalony]

I am evaluating whether to consider using the new MQTT driver for connecting WinCC OA to Maximo. The owners of Maximo prefer that our solution is bidirectional, which would require MQTT drive to both publish AND subscribe. The help is not decisive on the subject, but appears to only support write (publish). Does WinCC OA not support MQTT subscribe?

From the help (MQTT driver, basics):

The WinCC OA MQTT driver represents an MQTT client which can either publish or subscribe to data and allows to establish and handle connections to MQTT brokers

The help also shows address configuration panel, which shows as possible mode/direction options: publish, subscribe or both.
