We have an IIoT application built on Thingworx and Kepserver monitoring hundreds of machines in a manufacturing setting and corresponding Kepserver Ping Drivers to monitor their power on states. We're currently running Thingworx 8.5.6-b110 and KEPServerEX 6.10 and we are encountering issues with properties of Industrial Things that extend the PTC.Factory.DeviceThingTemplate stopping communication with their bound tags in Kepserver, despite the Thing reporting being connected.
Typical solutions have been to execute the RestartThing service on the affected Things. Occasionally, rebinding a single property fixes all of them when RestartThing does not work.
Has anyone else encountered this behavior? Any troubleshooting steps or tips we should be taking?
One other thing to note, when we restart Thingworx, all of the Industrial Things start in a disconnected state. So we have a service that is periodically triggered by a timer that will find disconnected Things that implement the PTC.Factory.DeviceThingTemplate and restart them to bring them online.
Our setup is the same as what is described here: https://community.ptc.com/t5/ThingWorx-Developers/Sharing-Use-Thingworx-to-monitor-Kepware-and-PLC/m-p/630822#M39857
