Kepware

Dear community members,   We are working on integration of Kepware and Thingworx using IoT Gateway plugin.   On Kepware IoT Gateway side status shows connected to the Thing, but in Thingworx, in remote things tab, We are unable to see any active remote thing.      

When I import the extension of kepware ,the error message is showing up. Could anyone help me?

I used OPC DA Server to connect KEPWare to Thingworx, I can read Item values, and I can use KEPWare client to write item value, but I can not write value to items in Thingworx even if I set item ReadOnly true.     {         "BaseType": "INTEGER",         "Name": "TemperatureUpperLimit",         "ReadOnly": false,         "Source": "Channel1.Device1.MyFBox.S7-1500.Item00.温度下限",         "SourceType": "System.UInt16"       }
