To connect Kepware to ThingWorx Server you need to provide the following details in the Kepware Project Properties :
1. Host : It will be the hostname of your ThingWorx Server
2. Port : Port at which ThingWorx is running
3. Application Key : Search for Application Key in ThingWorx Composer for the thing specified in Project Properties
For example i am launching ThingWorx using this URL : http://localhost:8080/Thingworx .
So the host would be localhost and port will be 8080.
Once these properties are updated , the Kepware will again try the connection to ThingWorx Server using above properties .
The host should be the address of your ThingWorx server and the thing Name is the name of the thing in ThingWorx that you will use to interface with your kepware server. This information and more can be found using this link:
