The KEPServerEX IoT Gateway Plug-in is not a requirement for connection with either the ThingWorx platform or the Manufacturing Apps. It is best to install this plug-in, as it enables the use of the Manufacturing Apps training sessions.
When completing a full install of KEPServerEX, the ThingWorx Native Interface will be included. This interface facilitates connection with the ThingWorx NextGen composer Industrial Gateway, (or with earlier versions of ThingWorx when set to Legacy Mode). For more information on KEPServerEX / ThingWorx version compatibility, see: ThingWorx / KEPServerEX version compatibility chart
Note: the ThingWorx Manufacturing Apps are compatible with ThingWorx v8.0 (and newer) and KEPServerEX v6.2 (and newer)
