IO-Item IP.21 gRPC Object
An IO-Item IP.21 gRPC object represents an item in an external IP.21 gRPC datasources. In other words, IO-Item IP.21 gRPC objects are created for each tag that is subscribed from a IP.21 gRPC datasource.
IO-Item IP.21 gRPC objects can be created under Datasource IP.21 gRPC objects, IO-Node IP.21 gRPC Record objects and History Transporter objects.
When creating an IO-Item object under a History Transporter, make sure to select the IO-Item type that corresponds to the imported data. On Datasource IP.21 gRPC and IO-Node IP.21 gRPC objects, only IO-Item IP.21 gRPC objects can be created.
