DeltaV Explorer displays the devices attached to the DeltaV PK controller as both physical and logical devices under the port. The logical devices contain signals that define the specific data items in the devices to be accessed. The device data can be mapped into DeltaV module parameters through the signal DSTs. The port, devices, and signals have configuration properties unique to each protocol.
When connecting devices to the DeltaV PK controller, data from those devices can only be referenced within the controller connected to the device. Device data cannot be externally referenced directly from another controller (or workstation) without going through a module parameter in the DeltaV PK controller.
