Equipment Hierarchy DeltaV supports a logical hierarchy for large systems which includes the following levels: Area - logical division of a process control system. Areas typically represent plant locations or main processing functions. Cell - may be class-based (available to the Batch Executive) or non class-based. The process cell can be used to organize units and modules within the plant area. Unit - adding control modules to a unit module allows you to take advantage of advanced alarming techniques. Module - links algorithms, displays, I/O, conditions and other characters (parameters) to the equipment. Modules can reside under any level of the hierarchy.
Important: DeltaV batch requires a full hierarchy of area , cell , unit in order to operate properly.

Device Signal Tags (DSTs) DeltaV Device Signal Tags are
Named items which attach an I/O channel to a control module
Typically named to match an instrument name
Define I/O properties such as –
Analog In vs. HART
–
DO Latching vs. Momentary
Workshop Defining Plant Areas The following workshop requires you to rename AREA_A as PLANT_AREA_A. From the DeltaV Explorer select: Control Strategies
AREA_A
Rename
AREA_A appears as a highlighted selection in the Contents window. Enter the new name PLANT_AREA_A before pressing the ENTER key.
Workshop Defining Plant Areas PLANT_AREA_B
The following workshop requires you to add PLANT_AREA_B. From the DeltaV Explorer select: Control Strategies
New Area
AREA1 appears as a highlighted selection in the Contents window. Enter the new name PLANT_AREA_B before pressing the ENTER key.

Downloads
Download the controller from the DeltaV Explorer by selecting: CTLR

Controller
Total/Full Download Download -- Transfers Controller configuration, setup data and cold restart memory from the configuration database of the Professional Plus to the controller(s) and/or workstation(s) run time database. Downloads are performed from DeltaV Explorer or Control Studio. Two Main Types of Downloads:
Total/Full Download -- Downloads the entire configuration for the selected node (controller or workstation). A total/full controller download will download all control modules assigned to the selected node. Control parameters will go to configured default values. This download type is performed from DeltaV Explorer.
Important: It may not be desirable to perform a Total/Full Download on a running process.
Partial Download -- Downloads only specific parts of the configuration ie; a single control module. This only affects the control module that is being downloaded. All partial downloads are performed from the DeltaV Explorer or Control Studio.
Download Status Indicators A triangle with a question mark ? indicates that some of the node’s database parameters may not match the parameters in the node itself. A manual request is required in an effort to update the download status. Update the download status manually to determine if a download is required. A blue triangle indicates that some of the node’s database parameters do not match the parameters in the node itself. If you perform a download, some changes will be made to the node. If this indicator is not present, no download is required. A yellow triangle
indicates no configuration.
Download Subsets Download Subsets — Configuration data that is not directly related to a control module.
Setup Data — includes named sets, parameter security, cold restart information, redundancy information, alarm preferences and event chronicle definitions. Setup data can be downloaded to Controllers and Workstations. Performed from DeltaV Explorer.
Changed Setup Data — Sends only changed setup data items.
Controller Cold Restart Memory — Updates the controller non-volatile memory so that the Cold Restart download script is valid. Should be performed after any of the following tasks:
–
Controller Upgrade
–
Decommissioning and re-commissioning
–
Partial download and/or Uploads
This can be performed without affecting working configuration in the controller! Performed from DeltaV Explorer.
Download Subsets Re-send Last Known Good Download — Sends the last successful total
download to a node without going to the database. This is useful for situations where a controller has been replaced. This function enables you to bring the new node up to the previous operational status without downloading recent edits to the configuration. Performed from DeltaV Explorer
Update Download Status — Updates the download status of the individual Nodes or Network depending on where it is initiated. Performed from DeltaV Explorer.
Workshop Completing the Configuration You will notice, after configuring the channel, that a blue triangle with a question mark appears next to the CTLR, I/O and card listing in the tree. You must check the download status and/or download the controller to remove the blue triangle.
Workshop Updating the Download Status Update the Download Status by selecting from the DeltaV Explorer: CTLR
Download Update Download Status
The blue triangle will either disappear following the update or will remain; indicating that the controller must be downloaded.
Workshop Downloading the Controller Download the controller by selecting from the DeltaV Explorer: CTLR

You will be required to respond to several options while stepping through the download process.
Workshop - Downloading the Controller
Verify the configuration dialog box provides the opportunity to check selected items for unresolved references and other configuration problems before downloading. You will be alerted to problems and given the opportunity to resolve them before continuing with the download.
The cautionary note above gives you the opportunity to abort the controller’s pending download. Click the Yes button if you wish to continue.
Downloading Dialogue Box
Downloading Dialogue Box The Downloading Selected Objects dialog box above displays the download’s progress. The checkmark beside each item indicates that the function is complete. As a specific event is processing, it is displayed as bold type. Highlighted items are events that do not need to be performed during the current download.
Creating Log File creates the log file for the download which is stored on the hard drive. (C or D:\DeltaV\DVData\DownLoadProgress.log)
Performing Upload Checks verifies values on uploadable items.
Performing PreDownload Checks determines which items are installable, loaded, created, licensed and if the user has download privileges.
Performing Dependency Checks are initiated when fieldbus devices or modules with fieldbus blocks are included.
Click the Close button to continue when the download is complete.
Workshop Downloading the Controller Download the controller to remove the blue triangles.
