You can upload parameter values from function blocks running in a commissioned fieldbus device to the database. This is useful if you want to ensure that factory-set parameter values are maintained in the database or that values modified by a technician in the field are uploaded to the database. Parameter changes to the following function blocks can be uploaded to the database: AI, AO, DI, DO, fieldbus Multiplexed AI, fieldbus Multiple DI, fieldbus Multiple DO.
Unlike controllers where the system detects a need to upload changes, the system does not detect a need to upload changes to fieldbus device parameters. To upload a fieldbus device, select the device in the DeltaV Explorer, and select Upload Function Blocks. There is no need to download the device after an upload.
