Thingworx Protocol Adapter Toolkit - Write from Thingworx to Edge

Hi all!

I saw Liveworx 2018 demo with PAT with bidirectional connection. (MQTT channel)

I am ok with EDGE -> Thignworx connection. I understand also how Egress message is working.

My question is if it is even possible to send request to PAT from Thingworx without any EDGE based trigger?

I saw remote service on the example WeatherThing, but cannot find any reference in code.

How it can be done in PAT?

Regards,

Adam
