1.2 PI Tags

14


What is a PI Tag?

It is a unique storage point for data in the PI system. It is simply a single point of measurement.

15

Examples A flow rate from a flowmeter A controller’s mode of operation The batch number of a product Text comments from an operator The results of a totalizer or calculation


PI Tag Attributes

Each PI Tag has a set of attributes for: Describing the tag to a User/Client Application

o “How is the information displayed?” Describing the tag to the Control System Interface

o “How is the information found?” Describing the tag to the PI Server

o “How is the information stored?”

16


PI Tag Attributes – Display

Tag name: unique name of the PI point Descriptor: PI tag description EngUnits: Engineering units PointType: type of variable stored Zero, Span and Typical value: minimum, range

and typical values Point source: allows grouping of PI tags by data

interface (DCS,PLC, or other sources)

17


1.2 Data Flow


Data Tests

Every value can go through 2 data screeningtests before being archived:

Exception Test “Send only significant changes in data to the

server”

Compression Test“Store only data needed to reliably represent

process behavior”

Exception Test (Interface Level)

Exception Test:

+ ExcDev

- ExcDevCurrent Snapshot

• New values outside the box violate the Exception test.

• The Exception Test is performed by the interface• When a value violates the Exception test, this value

and the previous one are sent to the PI Server.

22


Exception Test

When a value passes this test, that value and the previous value are reported. Why? To have a better representation of the actual tag behavior

The current snapshot value and timestamp are: 70.3 10:00:00

Which pass the exception test (not including previous values):

26


Turning Off Exception?

Behavior of ExcDev = 0, ExcMax = 0, is that Exception Test is turned off All values are sent to PI. This will increase the traffic between the data

collection node and the server.

27


Compression Test (PI Server)

Compression Test:

Last archived value

• If a value between the last archive event and the current snapshot is outside the box, the current snapshot violates the compression test. In this case, the value previous to the current snapshot will be archived.

• The Compression Test is done by the PI Server• Compression can be turned off with the Compressing attribute

+ CompDev

Turning Off Compression?

Behavior of Compression Compressing set to Off: all exceptions are archived

(no compression) Better Compressing set to ON, CompDev set to 0:

successive identical values (or values aligning perfectly) are not archived. This is much more efficient

32


Data Flow

The exception and compression specifications should be adjusted to achieve efficient archive storage without losing significant data.

Exception and Compression Attributes

Each PI Tag can be individually configured for its exception reporting and compression

Recommended Data Compression Specifications

Set the Compression Deviation to the minimum change that is measurable by the instrument.

Set the Exception Deviation to ½ of the compression deviation

Note: these are starting point recommendations.

Note: ExcMin, ExcMax, CompMin and CompMax are in SECONDS

Using Data Sets

179


More about Data sets

Elements which include data from a data set are updated automatically

Many elements of a ProcessBook can use the same data set simultaneously

Different ProcessBooks can include the same Data set

Modification of a data set will only affect elements of the current ProcessBook (.PIW) and display (.PDI)

180


Modify a Data set Important to verify which elements use a Data set

prior to modifying it The Show Use button of the Data Sets screen shows the

list of elements using a given data set To modify a data set, use the Edit button.

Modifications will affect all elements using this Data set

181


Copy a Data Set

Allows using data sets in other ProcessBooks In the source ProcessBook file (.PIW or .PDI):

1. Open the Data Sets dialog box (Tools > Data Sets)

2. Select the data set (or sets) you want to copy

3. Click the Copy… button

4. Select the destination file in the dropdown list Both source and destination files must be open

5.0 PI Module Database


Objectives Describe the PI Module Database structure Integrate the PI Module Database in PI ProcessBook

PI Module Database

199


PI Module Database

Each PI Server has its own PI Module Database (PI ModuleDB)

The PI ModuleDB is used to organize an enterprise’s information streams into logical sub-areas

The path to a certain area is called a context If the context (plant, unit, etc) is changed, the

referenced PI points will change, without having to search again for their tag names

200


PI ModuleDB – Physical Model

Department

Unit

Enterprise The structure of the PI ModuleDB allows the information to be stored hierarchically in relation to a physical model, a business model or an application model.

Division

Location

Equipment

Equipment Class

201


PI Module DB – PI Modules

Each module has: Configurable information – PI Properties Linked tags – PI Aliases Dated versions - Revision number, Version number,

Effective Date, Obsolete Date and Query Date System assigned information – UniqueID, Owner,

Parent list, etc. Sub-Modules with the same characteristics – PI

Modules

202


PI Module DB – PI Properties

PI Properties are collections of named values that can store information related to a PI module

A PIProperty has a name and a value The Value can be nearly any type: string,

numeric, date, etc. PIProperties are used to store information about

a module, example: Serial number Installation date Name of the technician who performed the installation


PI ModuleDB – PI Properties

PI Properties can also be hierarchical

204


PI ModuleDB – PI Aliases

PI Aliases let you configure common names to access real time information => PI tags

205


PI Module DB – PI Aliases

Temperature identification without aliases

RX:TC143.PV RX:TC144.PV RX:TC145.PV RX:TC146.PV

Temperature identification with aliases

Temperature Temperature Temperature TemperatureReactor1 Reactor 2 Reactor 3 Reactor 4

Reactor1 Reactor 2 Reactor 3 Reactor 4


Tag Search Window – Alias Search

Search by browsing the PI ModuleDB or specifying search criteria

You can filter by context, module name, alias, heading set and heading

The result pane shows the underlying tags for the aliases found

207


Module Relative PI ProcessBook Displays

208

Problem• A site has 100 units,

exactly the same• Need to monitor each

one• PB requires the creation

of a display for each unit

Solution• Define the units as

modules with aliases• Select a “template” unit• Design the display

using aliases from the “template”

• Shift the context from one unit to another

• One display can be used to monitor all 100 units


Accessing PI ModuleDB in PI ProcessBook

To add modules to a display, go in

Tools > Module Context > Add Module

209



210

Choose Modules that you wish to be included in the display

They will then be available in that display for reference



211

3. Choose the item you want to display and click OK

2. You will see a list of all the aliases and properties defined in the current

context

1. Click Module Context in the dropdown list beside the Tag Search

button

1.

3.

2.


The result: a streamlined approach

One display for multiple modules!

212


Displaying the Current Context

You can display the current context being used with a value symbol

213


What needs to be done in a PI ProcessBook display in order to access the information contained in the PI ModuleDB?
