At the moment I trie to use Thingworx 8.5 + Manufacturing Apps + KEPServerEX 6.7
I want to publish MQTT Messages Thingworx with the KEPServer and the MQTT Driver (Not MQTT Extension).
I successfully subscribe the Data in Thingworx.
I created the Tags in KEP and I see the messages from a MQTT Client (Node-Red) via the MQTT Broker (Mosquitto) to the KEPServer.
In Thingworx I created with Discover the Thing (Remote Thing) with the Binding to the KEPServer Tag.
Everything works fine and I see the Value in the Properties.
But if I trie to change the value in the properties i see in the event log from KEPServer:
Warning MQTT Client Channel2.Device1 | Unable to write to address on device. | Address = 'thingworx+invalue'.
In KEP the Client Access = Read/Write. if change it to Read only I get an error in Thingworx.
In the MQTT Manual I found:
Reading data from a MQTT server (writes are currently not supported)
But if I use in from the Channel "Simulation Examples" the Device "Functions" I can publish messages.
Like in the video "https://www.youtube.com/watch?v=yTaoGtQ5JkA".
Somehow its possible to publish.. anyone an idea?
Solved! Go to Solution.
I found more or less a solution for the problem.
If I change the device to simulated, I am able to set the values in thingworx and they get published. Problem with that solution is, that the other way around doesnt work anymore.
Simulated Device | Enabled | Disabled |
KEP -> MQTT Broker possible | Yes | No |
MQTT Broker -> KEP possible | No | Yes |
so i will try to use two devices. One device in, and one device out.
