Publish MQTT Thingworx with the KEPServer

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?

Re: Publish MQTT Thingworx with the KEPServer

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.

Hi @dhmuech 

 

Are you able to update tag value using Kepserver OPC Client ?
