There are two variations of the local HMI (operator station) for the Standalone DeltaV PK controller: the DeltaV local panel HMI and the 3rd-party local panel HMI.
The Standalone DeltaV PK controller must be commissioned and authenticated; and, the relevant protocol enabled, before you can communicate with the local HMI panel.
The DeltaV HMI option is differentiated by hardware (local panel HMI or local HMI) only. Both hardware platforms are installed as a DeltaV Operator Station and are configured and downloaded using the Engineering Station. Because of utilizing the DeltaV Operator Station installation, The DeltaV HMI can be converted (by running Workstation Configuration and supplying a valid DevData.cfg file) to a licensed DeltaV Operator Station when merged with the DeltaV balance-of-plant system.
DeltaV HMI basic functionality can be expanded with ST scale-up licensing, for example, the DeltaV HMI can serve as the DeltaV Batch Executive and the DeltaV Batch Historian when appropriately licensed.
The optional Modbus local panel HMI is not installed with DeltaV nor configured using the Engineering Station. The Engineering Station enables the ModbusTCP communication and maps DeltaV parameters to the registers and coils specified by the 3rd-party HMI software. The 3rd-party software in the local panel makes use of the registers and coils.
3rd-party software in the local panel can also communicate with the PK controller's OPC UA server. Configuration is determined by the 3rd-party software installed on the local panel.
