Describe security levels
Introduction
In the previous exercise you learned how to start the Experion PKS® Station with Station based
security. You now need to know about the security used by Experion PKS®. There are several
levels of security and each level determines the tasks that can be performed at that level.
Main Idea
Station supports two types of security, only one of which you will use.
•
Operator-based security – If you have been assigned a user name and a password
or your Station user name and password are the same as your Windows user name
and password.
•
Station-based security – If you have not been assigned a user name. When you
start Station, you are automatically assigned to the OPER security level. You can
subsequently change to a higher level providing you know the password for that
level on that Station.
Explanation
Security Levels
Your security level determines which tasks you are permitted to perform. However even if you are
allowed to perform a particular task, you may be prevented from performing that task under certain
circumstances.
TIP
If you attempt to perform a task that requires a higher
security level, the following message appears in the
Message Zone:
Higher Security Level Required

Describe security levels
Your security level appears at the right of the Status Line.
In the following example, the security level of this station is MNGR (Manager).
The security levels are: (from lowest to highest)
•
VIEW Only
•
ACK Only
•
OPER
•
SUPV
•
ENGR
•
MNGR
Security Level
Description
View Only
Permits you to look at displays, trends, and reports, but no process changes
are permitted.
Ack Only
Permits you to acknowledge alarms and look at displays, trends and
reports, but no process changes are allowed.
OPER
Permits you to acknowledge alarms and make process changes to those
points that are in areas assigned to your Station or your Operator ID.
SUPV
Gives you all the permissions of the OPER level and the ability to change or
configure Trend set and Group Displays, Holiday and Shift Details,
Configuring recipes, and Alarm Duration Reports.
ENGR
Gives you all the permissions of the OPER and SUPV levels and the ability
to make changes to point configuration and other systems.
MNGR
Gives the user permissions to change everything that can be changed or
configured on the system.

Introduction
In the previous lesson you learned how to sign on the Experion PKS Station using Station based
security. In this lesson we will discuss the two types of security that can be used.
The two types of security for the Experion PKS® Station are:
•
Station-based security. This is the default level for Station access.
•
Operator-based security. This provides a higher level of security than Station-based
security.
Main Idea
Station-based Security
Station-based security is the default used for Station access.
Operator-based Security
Operator-based security provides a higher level of security than Station-based security.
Explanation
Operator-based Security
Operator-based security provides a higher level of security than Station-based security. There are
two types of operator-based security:
•
Traditional operator accounts – the Experion PKS operator account does not have an
associated Windows account.
•
Integrated accounts – the Window’s accounts are used to authenticate the user and
operator definition in Experion PKS to authorize the user.
In general, Operator-based security with traditional operator accounts, works as follows:
10
•
Each user is assigned a specific security level.
•
Users cannot access any Station functions unless they enter a valid ID and password.
•
To access a higher security level other than the one they are currently using, users
need to sign off and sign on again as a different operator who has the higher security
level.
•
Areas are assigned to the operator irrespective of which Station they are currently
logged onto. Who you are not where you are determines the areas that you can
control.

Differentiate between station-based and operator-based security
Station-based Security
Station-based security is the default used for Station access. Station-based security works as
follows:
6/11/2004
•
Station starts without prompting users to enter any form of operator ID or password.
•
The initial security level setting allows users to perform the basic operating functions
associated with the user level of OPER (for example, acknowledging alarms and
controlling points).
•
Users only need to use a password if they want to change to a higher level of
security.
•
Area assignment applies to the Station not to the operator.

Recognize display objects
Introduction
So far you have used the Station tools and the function keys to call up displays on the Station.
There are other ways to call up displays or initiate action. All of the text, lines and shapes that
make up a graphic display are called display objects. These objects are either selectable or not
selectable.
A selectable object can be scripted (written code) to:
•
Call up displays
•
Call up other objects
•
Initiate actions
In this lesson you will learn about some of the display objects used on the Experion PKS displays.
Main Idea
Custom Graphics contain many display objects that are selectable, change behavior indicating a
status change in the process or provide other information that is helpful to the operator.
Display objects include the following:
•
Pushbuttons
•
Alphanumeric fields
•
Scrollbars
•
Indicators
•
List and combo boxes
•
Checkbox
•

Identify functions of Area and Point
Identify functions of Area and Point
Introduction
You have learned about point Detail and Group display components and where information is
located on the Detail Pages (Tabs). Before you can control a point you must have access to the Set
point, Mode and Output parameters. You are given access to those parameters through area
assignment.
If your system is divided into areas, your access to those areas of the system can be restricted. In
areas where you do have access, the tasks that you can perform may also be restricted.
Each area represents a portion of the process; you may have several areas assigned to you: some for
control purposes and others with VIEW ONLY restrictions.
Main Idea
The Experion PKS database can be partitioned into areas to control access to a particular section of
the plant or process. Typically, these areas match actual physical areas or sections of a site or
building.
Only Stations or Operator IDs configured to have access to a given area are able to view Alarms
and Custom displays or Control Points for that area. For example, if you have VIEW access to an
area in your system, you can only view items in that area; you cannot make any changes such as
acknowledging alarms or changing point parameters.
The Experion PKS database contains a System area. System items such as printers, channels, and
controllers are automatically assigned to the System area.

Change the Output (OP)
Change the Output (OP)
Introduction
The output (or OP) can be used to read and write an analog value. An operator can only change OP
if the mode is set to MANUAL. The OP value is always in the range of 0% to 100% and is intended
to indicate % open of a valve.
Main Idea
Output Changes
OP is the opposite of PV, that is, OP represents values that can be changed by an operator or by
another component of the system when performing supervisory control. Usually, only an operator
can change the OP of a point if the mode of that point is set to MANUAL.
Explanation
There are several ways to select the output for change:
•
Select the alphanumeric box, type in the desired value, and press the ENTER key.
•
Select the alphanumeric box and use the raise or lower tools on the toolbar.
•
Select the alphanumeric box and use the function (<F9> or <F10>) keys.

OP limits can be found on the PV and OP page of the Detail display. These limits apply to the point
when it is in AUTO or CAS (cascade) mode. When the point is in MANUAL mode, the OP can be
stroked by the operator (from –6.0% to 106.9%).
Output alarms can be set for a point. You can see that the OP High and/or OP Low alarms have
been assigned to a point by looking at the Alarm Page of the Detail Display.

PV Tracking is a setting that assists the operator with transferring a point from MANUAL mode to
AUTOMATIC mode without causing a process upset.
Main Idea
The key characteristics of PV Tracking are:
Characteristic
Set point value
Description
SP is made equal to PV when the
controller is in MANUAL mode.
When the controller is returned to
AUTOMATIC mode, PV and SP are equal.
A smooth transfer to AUTOMATIC
mode is made.
The Operator does not have to change the
SP to match the PV.
Explanation
The PV Tracking can be seen in the Setpoint tab of the Points Detail display.
When the Enable PV Tracking checkbox is selected, the Set Point will match the Process Value
when the point is in MANUAL mode or initialized (secondary point is not in CASCADE mode).

Identify the Point, the ID, and the Parameters
Explanation
Main Parameters for Standard Point Types
Parameter
PV (Process Variable)
Description
The current value or state of the point.
This input is known in Experion PKS as the PV (Process Variable) of
a point, because it represents values that are a function of the
process (or the controller or both).
An operator cannot change process variables.
SP (Set Point)
Only applicable to analog points.
The SP is the desired value or state of the point.
OP (Output Value)
Only applicable to analog and status points.
The OP is the raw (uncalibrated) value of the point. In the case of an
analog point, OP is expressed as a percentage of the full value. In the
case of a status point, OP has four possible values (0 to 3).
MD (Mode)
Only applicable to analog and status points.
The MD indicates the manner in which the point is being controlled.
For example, if you want to change a point's SP, you first need to set
MD to Automatic. If MD is set to Manual, it means that the point’s
output is being controlled directly by the operator.
Process Variable (PV)
PV Status points are used to represent the current state of the field device or process. For example,
four distinct states for a valve could be defined as: TRAVEL, CLOSED, OPEN, and FAIL.
The PV of an analog point represents the current reading (represented in engineering units) of the
field device or process. PVs are often used to represent the process variable of a control loop.
Set Point (SP)
The set point can be used to read and write an analog value in a controller. Set points are
represented in engineering units and are often used to represent the ideal operating value for a
control loop.
Control Mode (MD)
The current control mode of a point determines whether or not an operator is permitted to control
the OP or SP of the point.
The available control modes are: manual, automatic, cascade, and computer, although, cascade and
computer are only available with specific controllers. Most Experion PKS device interfaces support
just single bit modes (that is, values of 0 and 1, displayed by default as MAN and AUTO).

Introduction
In this lesson you will learn about the parameters that determine the control mode of the process
points.
Main Idea
Point Mode (MD)
The mode of a status point is used to determine whether or not an operator is permitted to control
the output value.
The two most common modes are:
•
Manual
•
Automatic
The available control modes are: manual, automatic, cascade, and computer, although, cascade and
computer are only available with specific controllers.
Mode Attribute (MD Attr)
Mode attribute determines whether an operator or a user program has the authority to change certain
variables such as Mode, OP, or SP.
Normal Mode
When defining a point that includes a control, the builder can specify what is to be the normal mode
for that point.
The normal mode applies:
•
By default for this point.
•
When an authorized operator presses the appropriate function keys to reset the mode
after manual intervention.
For most points, the normal mode is AUTO.

Explanation
Analog Mode (MD)
The mode (MD) is used to determine whether or not an operator is permitted to control the output
value.
The two most common modes are:
•
Manual
•
Automatic
Property
Description
Man
When the manual mode is set, an operator is permitted to change either the set
point or the output value.
Auto
When the automatic mode is set, the controller (or sometimes the server)
controls the output and operators cannot change the output value unless the
Disable mode checking on output is set.
Casc
Cascade mode is specific to S9000, TDC, and UDC controllers.
The cascade mode is used when the SP is coming from the output of another
PID loop within the controller (that is, PID loops are cascaded together). When
the mode is set to cascade, operators cannot change either the set point or the
output value.
Comp
This mode is specific to TDC controllers.
The computer mode is used when the SP is coming from a computer that is
performing automatic control. When the mode is set to computer, operators can
change either the set point or the output values.
Normal Mode
If the normal mode is configured correctly an operator doesn’t have to know what mode a point
should be in.

Describe the Term: Setpoint
Introduction
In this lesson you will learn about the parameter called Set Point or SP and the procedures to change
SP depending on the points configuration.
Main Idea
Set point (SP)
Only applicable to analog points.
The SP is the desired value or state of the point. If, for example, a point represents room
temperature, changing the SP causes the room to change to that temperature.
Set point is the desired value of the process and can be set by:
•
The operator
•
The sequence program
•
The controller or another controller
Explanation
The operator changes the set point (SP) of a controller by placing the controller in the proper mode
and selecting the SP and then changing it to the desired value.
Step
How the set point is changed on a Single loop controller:
1
Place point in AUTOMATIC mode and the mode attribute to OPERATOR.
2
Select the set point parameter and type in a new set point value and press
the ENTER key.
3
You could select the set point parameter and use the <F9> key to increase
the value or the <F10> key to decrease the value.
If two or more points are cascaded (linked together), the primary point sends a set point to the
secondary point’s set point parameter.
Step
How the Set point is changed on a cascaded controller:
1
Place the secondary point in CASCADE mode and the mode attribute to
OPERATOR.
2
Adjust the set point or the output of the primary point.
The set point of secondary point will change based on the primary point’s
output.

Process Operations
Describe the Term: Setpoint
Controllers can be controlled by a sequence (computer) program rather than by the operator.
Step
How the Set point is changed by a sequence program:
1
Place point in AUTOMATIC mode and the mode attribute to PROGRAM.
2
The sequence program script writes a new set point value to the controller.
The Controller can be configured with PV tracking that enables the controller to adjust its own set
point when in Manual mode making the set point equal to the process value.
Step
1
How the Set point is changed by PV tracking:
Place point in MANUAL mode and the mode attribute to OPERATOR.
ATTENTION
The set point (SP) is immediately made equal to the process value
(PV) (PV Tracking Option).
2
As the output of the point causes the PV to change, the SP changes to match
the PV value.
This feature is designed to prevent the process from being bumped when the
point is transferred to automatic control mode.

Main Idea
The PV of an analog point represents the current reading in engineering units of the field device or
process.
Explanation
The PV has a:

•
Range Low Value
Process Variable
Definition
PV High Range
The highest and the lowest valid values of the range for this point
PV Low Range
For example, if the maximum output of a temperature transmitter
represents 600 degrees Celsius, and the minimum is zero degrees
Celsius, the Range High Value is 600 and the Range Low Value is
0 so that the server can correctly scale or convert the raw data
captured from the controller.
The PV of a device point represents the current status of the field device. For example, the four

Describe the Term: Output
Introduction
In this lesson you will learn about the control parameter output (OP).
Main Idea
Output value (OP)
Only applicable to analog and status points, the OP is the raw (uncalibrated) value of the point. In
the case of an analog point, OP is expressed as a percentage of the full value. In the case of a status
point, OP has four possible values (0 to 3).
PID Point Output
The OP value is always in the range of 0% to 100% and is intended to indicate the percent open of a
valve.
If the valve is reverse acting, for example, 4 mA represents the valve fully open and 20 mA
represents valve fully closed, then the OPReverse parameter should be enabled so that the OP
indicator still shows % open. The output (OP) can be used to read and write an analog value. An
operator can only change it if the mode is set to MANUAL.
Device and Status Point Output
OP represents values that can be changed by an operator or by another component of the system
when performing supervisory control. Only an operator (usually) can change the OP of a point if the
mode of that point is set to manual. In the case of a status point, OP has four possible values (0 to
3). Device points may have as many as eight (0 to 8) possible values.

Describe the Term: Initialization
Introduction
Initialization (INIT)
Allows cascade controls to be re-established after they have been interrupted without causing bumps
in the process.
Main Idea
Initialization Propagation
Initialization requires each Regulatory Control block in a cascade to check its secondary to see if
the cascade has been broken. If it has, each block will initialize and provide an initialization request
and initialization value to its primary. In this way, the initialization will start at the final control
element and propagate upstream.
Explanation
Points with Secondary Initialization, within the Control Option area, the, enabled will initialize
when the secondary is not in cascade. If this parameter is disabled initialization will not take place.

Introduction
The mode (or MD) is used to determine if an operator is permitted to control the output value
(manual mode) or the set point value (automatic mode).
Main Idea
Control Modes
The current control mode of a point determines if an operator is permitted to control the OP or SP of
the point.
The available control modes are: manual, automatic, cascade, and computer, although, cascade and
computer are only available with specific controllers.

Change Mode
Explanation
Property
Description
MAN
When the manual mode is set, an operator is permitted to change either the set
point or the output value.
AUTO
When the automatic mode is set, the controller (or sometimes the server) controls
the output and operators cannot change the output value.
CAS
Cascade mode is specific to C-200, S9000, TDC, and UDC controllers. The
cascade mode is used when the SP is coming from the output of another PID loop
within the controller (that is, PID loops are cascaded together). When the mode is
set to cascade, operators cannot change either the set point or the output value.
Normal Mode
When defining a point that includes a control, the builder can specify what is to be the normal mode
for that point. The normal mode applies by default for this point. When an authorized operator
selects the NORMAL option from the Mode list box, it resets to the mode specified by the normal
mode parameter (NORMMODE).
For most points, the normal mode is AUTO.

x_AC12 is the Primary and x_FC19 is the Secondary in a Cascade loop.
When the secondary is not in cascade, the Primary shows the initialize
message of INIT to advise that the operator has control of the Secondary
point.
13
Return the point x_FC19 to the normal mode.
Notice that the INIT message has been removed from the Primary point

Introduction
The set point (or SP) can be used to read and write an analog value in a controller. Set points are
represented in engineering units and are often used to represent the ideal operating value for a
control loop.
You will practice changing the set point from the Group faceplate display using the number keys
and the <F9> and <F10> keys.

Change the Set Point (SP)
Introduction
In previous lessons you have made SP changes using keys and toolbar buttons. In this lesson you
will use these same tools while displaying the point in the Point Detail display.
Main Idea
Use the same methods to change SP (set point) from the Detail display as you used in the Group
display.
•
Type in the SP in the alphanumeric field
•
Select the SP and use <F9> and <F10> keys to increase or decrease the SP in 1%
increments
•
Select the SP and use <ALT>+ <F9> or <F10> keys to increase or decrease the SP
in 10% increments (configured rate may vary from system to system)
•
Select the SP and use the Raise and Lower toolbar buttons
Explanation
The Detail display has a Setpoint tab that contains the Set Point Input Range limits and the SP
Processing/Tracking configuration for the point.
You cannot make changes to this page at the OPER level. However, this page displays the largest
and smallest SP values for the point and indicates if the point has the PV Tracking enabled.

Introduction
In previous lessons you have been using the Detail display to make control changes and view alarm
limits. It is now time to learn more about the Detail Pages/Tabs and what information is available.
Main Idea
Each point type has a Detail display that consists of a Faceplate and a Main Page, Chart Page, and
several others. These pages contain all the configuration information about the point. Most of the
settings require an access level greater than OPER for changes. However, as the operator you will
find some of this configuration information very useful when you are investigating alarms, range
limit messages, interlocks, Redtags and other conditions that limit or control what you can do to
control the point.

Start the SP Ramp Option for a Controller
Introduction
In this lesson you will learn to operate a PID controller that has the Set Point ramping enabled. This
feature allows you to change a SP in small increments over a period of time. The PID point makes
the changes and you specify to final set point and the time or rate of change.
Main Idea
Set Point (SP) ramping option.
This allows the set point target value processing to provide a smooth transition from the current set
point value to a new value. It ramps the set point (SP) from the existing value to a desired value
over a period of time.
Terms
Requested Ramp Rate
Specify a value in engineering units per minute to define the normal ramp rate when set point
ramping is enabled.
This parameter allows starting set point (SP) ramping without having to specify a ramp time.
Normal Ramp Rate may be either NaN (Not a Number) or greater than zero.
NaN means ramp time = 0.
Maximum SP_DV Deviation
Specify a value in engineering units per minute that represents the maximum ramp deviation when
set point ramping is enabled.
If the maximum ramp deviation is ever exceeded, SP ramping stops until the PV input catches up
with the set point (SP) within the specified deviation range. Maximum Ramp Deviation may be
either NaN (Not a Number) or greater than zero.
NaN means "do not check ramp deviation."

Operate Cascade Loops
Introduction
In this lesson you will
•
Discover why cascade loops are used
•
Identify control functions that enhance operation of cascade loops
− Process Variable tracking
− Initialization
Main Idea
Cascade control strategy is a multiple-loop system where the primary variable is controlled by
adjusting the setpoint of a related secondary variable controller. The secondary variable then affects
the primary variable through the process.
The primary objective in cascade control is to divide an otherwise difficult to control process into
two parts, whereby a secondary control loop is formed around a major disturbance thus leaving only
minor disturbances to be controlled by the primary controller.
Cascade control uses the output of the primary (master) controller to operate the setpoint of the
secondary (slave) controller as if it were the final control element.
This is an Example a Cascade Loop
Point
X_FC20
Reason for using Cascade control
Allows this faster secondary controller to handle disturbances in the secondary
loop.
Allows the secondary controller to deal with non-linear valve x_FV20 and other
final control element problems.
Provides limits on the secondary variable.
Operator

Operator can directly control secondary loop during certain modes of operation,
such as Startup.

Process Operations
Operate Cascade Loops
Point
X_LC16
Reason for using Cascade control
Provides better control of the Level (primary variable)
The primary is less affected by disturbances.
Provides quicker recovery from disturbances.
PV Tracking
The PV Tracking option sets SP equal to PV when a cascade is broken due either to function block
initialization or operator or program action (such as, setting the mode to Manual).
Typically, PV tracking is configured for PID blocks in a cascade configuration strategy. This allows
the PIDs to resume control with no error after initialization or when they are taken out of Manual
mode.
If PV tracking is configured, the PID block sets SP equal to PV (subject to SP limits) when either of
the following conditions exist:
•
PID block is in Manual mode
•
PID block is initializing and not in Auto mode.
ATTENTION
•
PV tracking does not occur on recovery from a bad PV.
•
PV tracking does not occur if PID block is in Auto mode.
−
If PID block is in Auto mode, it means SP is normally
stored by the user.
−
If PV tracking is initiated, this Operator entered SP
value is lost and SP is determined by PV until the
mode is returned to AUTO.
In Automatic mode the Operator controls the setpoint of the controller.
Describe the term initialization
Initialization Propagation allows cascade controls to be re-established after they have been
interrupted without causing "bumps" in the process.
Initialization requires each Regulatory Control block in a cascade to check its secondary, to see if
the cascade has been broken. If it has, each block will initialize itself, and provide an initialization
request and initialization value to its primary. In this way, the initialization will start at the final
control element and propagate upstream.

Introduction
In previous lessons you have been using the Standard displays to make control changes via the
Group and Detail faceplates. In this lesson you will practice making changes and monitor the
process with custom graphic displays and the faceplate that is part of the Experion®PKS HMI Web
graphic package.
Main Idea
Custom graphics are becoming the primary operator interface to the process because the custom
graphic can provide a more complete picture of the process and the status of the equipment. A
custom graphic can contain many process points, their important parameters, and targets to call up
faceplates, list boxes, dialog boxes and other displays.
Explanation
Lets look at some examples of Custom graphics that were built using the HMI Web tools and
objects that come with the system.

Introduction
In previous lessons you have been operating the process and have called up the Detail pages for the
process points. You have identified the:
•
Alarm limits and setting on the alarm tab of the Detail display.
•
Alarm limit bars on the Faceplates.
• Alarm tools on the Menu bar and on the Toolbar.
You are now ready to use the Alarm Summary display and become familiar with its tools. The
various type and causes of alarms and the different ways that alarm states can be shown.
Main Idea
Alarm indication of Process Upsets
The Station application provides an Alarm Summary display that lets you view all the current and
unacknowledged alarms in the system, or just those alarms with a configured priority level of high
and/or urgent, or just those alarms assigned to a given area.
The Alarm Summary display is the focal point for viewing alarms. Individual alarms can appear on
any display including
•
Detail
•
Group
•
Trend
•
User-built schematics (faceplate).
Alarms that are configured for a priority of journal are not displayed but can be included in a report
or logged in a printed journal.
Explanation
Status Line
The Station's Status Line provides an overview of your system's status. For example, a flashing red
field indicates that there is at least one unacknowledged alarm.

Frequently asked question about the Alarms display.
How many alarms can the Experion PKS System handle concurrently?
•
1000 active alarms
Is this the size of the alarm page buffer?
•
YES
What happens if there is an alarm overflow?
• In general, newer alarms replace older alarms. The Experion PKS Server can request
full alarm regeneration, if needed, and the ultimate data owning alarm blocks hold alarm
information, in case of a system alarm overflow.
If the alarm summary page is full, what happens with the alarms that follow?
•
Newer alarms replace older alarms on the alarm summary. An algorithm is applied to
discard the least important alarm from the list according to this schem.
− Discard any duplicate alarm; then,
− Discard lower priority alarm; then,
− Discard oldest alarm.
When are overflow alarms stored?
•
All alarms received are placed in the Event journal.
What happens to alarms when the Experion PKS Server is not running?
•
When the Server is restarted, all alarms generated by the Hybrid Controller are resent
to the Server database. Alarms will be regenerated in response to any of the
following events.
− Server startup
− Redundant Server failover
− Re-enabling alarms system-wide, by area or by point
− Control Processor startup
− Redundant Controller switchover
− ControlNet communications failure and recovery
− Setting a CEE's state to RUN (Control Execution Environment)
− Setting a CM's state to Active (Control Module)

When are alarms timestamped?
•
Alarms are timestamped when received at the Server database.
Can alarms be disabled during maintenance periods, plant commissioning or other circumstances?
•
Alarms can be disabled through several means, depending upon the extent of the
silencing required. You can disable alarms on a point (CM or SCM), area, or system
wide basis through Station.
Navigating the Alarm Summary
There are several ways to scroll the list of alarms on the Alarm Summary. You can:
•

Introduction
Alarms
Alarms indicate unusual conditions in processes (excess pressure in a valve, low temperature of an
oven, and so on) or in the system (such as the failure of a channel) that require operator action.
An alarm remains until the condition that triggered the alarm returns to normal and someone
acknowledges the alarm.
All alarms are recorded in the event log, including when it was generated, when it returned to
normal, and when it was acknowledged.
You can see and acknowledge alarms from these displays:
•
Alarm line
•
Alarms Summary
•
Custom display faceplate
•

Build a custom filter
Introduction
In previous exercises you have view the Alarm Summary display and acknowledged alarms. In is
lesson you will learn how to control what is on the display and how it is displayed. The filtering
and sorting function allow you to limit and organize alarms.
Main Idea
Changing What Is Shown In The Alarm Summary
ATTENTION
Depending on your security privileges, you may not be able to filter
and sort the Alarm Summary. The options that are not available to you
are disabled and appear grayed out.
By default, the Alarm Summary shows all alarms, with the newest alarm at the top. You can change
the Alarm Summary by applying filters and sorting the summary.
Explanation
Filtering the Alarm Summary allows you to show alarms that match the filter criteria and hide
alarms that do not match the filter criteria. For example, you can filter the Alarm Summary to show
alarms of a particular priority only, or you can filter the Alarm Summary to show alarms for a
particular area only. You can filter the Alarm Summary by any column in the summary.

Build a custom filter
Filtering
An easy way to filter the summary is to perform a "like currently selected" filter. For example, if
you want to see all alarms for a particular point. You can select an alarm for the particular point,
click the Source column and select (like currently selected). The Alarm Summary is filtered to show
all alarms in the summary that match the source (Point ID) of the currently selected alarm.
Sorting
Sorting allows you to set the order in which alarms appear in the summary. The sort order can be
ascending or descending. For example, you can sort alarms by date and time, in ascending order.
This means that alarms are listed in order of ascending date and time, that is, the oldest alarm is
listed at the top of the summary.
Using more that one Filter
You can apply more than one filter at a time and you can also filter and sort at the same time. When
the Alarm Summary is filtered or sorted, the column by which you are filtering or sorting is
highlighted.

Process Alarms
Using priorities to identify alarm conditions for corrective action.
Using priorities to identify alarm conditions for corrective action.
Introduction
The Alarm priority can be a useful tool to help you determine the correct action to take during a
process upset.
All alarms are assigned a priority to assist the operator in making decisions. These priorities are:
•
Urgent
•
High
•
Low
•
Journal
•
None
A secondary ranking is Severity, as a number between 0 and 15. This determines the alarm
processing order relative to other alarms with 15 being the most severe.
Condition can also be used to determine alarm type and permit you to view points with the same
type of alarms.
Main Idea
You can sort or filter alarms based on different criteria. Priority has three options:
•
Urgent
•
High
•
Low
You can select a point and choose to use it as the selection criteria (Like Currently Selected).
If you use the Alarms State field, you can choose to limit the view to only Active alarms, excluding
all those that have returned to normal.
You can choose to show a combination of selections such as:
Urgent or High and Active, sorted from the highest to the lowest priority.

Introduction
Changing the sample size and the sample interval when analyzing the performance of the process
enables you to view the trend in a more meaningful way.
The number of samples viewed increases the time span on the X-axis. For example 60 1-minute
intervals cover a period of one hour, or 120 samples at 5-second intervals cover a period of 10
minutes.
Main Idea
History File Sizes
What does Sample and Interval represent? How much history is available? The system has a
minimum file size; see the table below. Your system may have more history configured.
The duration and the number of samples for each history interval are shown in the table below.

Locate point values on a trend using the hairline function
Introduction
In the last segment you learned how to change the Samples and the Interval on the Trend display.
You are now ready to use the Hairline function to gather information about the plot at a specific
location on the graph.
Main Idea
Clicking in the graph area or the trend activates the hairline function. This function provides you
with the value and the time at the hairline position.
Explanation
When you are using the Trend displays you may want to identify the exact time that the process
reached a high or low point and the value of the high or low reading. The hairline function does
that on the bar and line graphs.

Select point parameters
Introduction
In the last section you learned how to turn pens on and off and to add and remove points from the
trend. It is possible just to change the parameter that is being trended rather than the whole point.
Main Idea
Changing the parameter requires knowing the correct parameter for the point.
If the parameter has been configured to be collected or historized, you will be able to display a
historical trend otherwise it will be a real-time trend. A real-time trend starts when you call up the
Trend display or select the Pen ON/OFF checkbox.
DACA= data acquisition block. The process variable for the controller is provided by the parameter
DACA.PV (signal in from the sensor).
PIDA = PID controller block. The output signal is sent to the final control element by the parameter
PIDA.OP. The setpoint also is part of the PIDA function block and is called PIDA.SP
Explanation
To change the trended parameter from DACA.PV to the OP, you need to know that the OP is really
PIDA.OP. Now it is a matter of selecting the Parameter list box and selecting the PIDA.OP
parameter.
Demo
To demonstrate this procedure, call up a Trend display and change the trend pen parameter from
DACA.PV to PIDA.OP.

Introduction
In the previous lessons you have learned how to control points, acknowledge alarms, call up the
standard displays and trend points.
You are ready to learn about Events and how to view them, print them, and add comments to an
event. An event is any significant change in the system, and includes alarms and operator actions.
Main Idea
Event
An Event is a significant change in the status of an element of the system such as a point or piece of
hardware. Some events may be classified as an alarm. Events can be viewed on displays and
included in reports.
Event Archiving
This is the Experion PKS function that allows you to archive events to a network fileserver, or to
tape or other backup medium.
Event Summary display example
By default, the Event Summary shows a live summary of events. That is, current events in the
system database with the newest events at the top.

Print or display alarm/event summary
Introduction
In an earlier lesson you learned about view alarms on the Alarm Summary display.
The Events Summary has many of the same viewing tools to help you filter events, sort events and
build custom reports. Filtering and sorting depend on security privileges so that you may not be able
to manipulate Event Summary viewing. The options that are not available are disabled and appear
dimmed. By default, the Event Summary shows a live summary of events, that is, current events in
the system database with the newest events at the top.
Main Idea
You can change how information is displayed in the Event Summary by applying a different view.
A view contains the information about filtering and sorting, which event line items are shown, the
displayed order, and the space provided for each item.
There are two predefined views.
These are:
•
All recent events with live update. Shows events as they are occurring.
•
All today's events snapshot. Shows all events that occurred today up until the view was
applied.
You can:
•
Change or select the date and time
•
Filter the Events
•
Sort the Events
•
Build custom filters using conditions
Explanation
You can change the Event Summary to show all events for the current day and for each of the last
seven days.
When you view events for the current day, you can manually update the summary to show events as
they are moved to the online archive.

Events
Print or display alarm/event summary
Filtering the Event Summary allows you to show events that match the filter criteria and hide events
that do not match the filter criteria. For example, you can filter the Event Summary to show events
that occurred on a particular day, or you can filter the Event Summary to show events for a
particular area only.
You can filter the Event Summary by any column in the summary.
Sorting allows you to set the order in which events appear in the summary. The sort order can be
ascending or descending. For example, you can sort events by date and time in ascending order.
This means that events are listed in order with the oldest event listed at the top of the summary.
You can apply more than one filter at a time and you can also filter and sort at the same time. When
the Event Summary is filtered or sorted, the column by which you are filtering or sorting is
highlighted.
Considerations
You can filter, but you cannot sort the live Event Summary display.

If you notice an event (such as a safety issue) that is not recorded by the system, but that you want
included in the Event Summary. Experion PKS allows you to manually record that event into the
system. Information, such as your user identification, date and time, and event category are
automatically stored with the newly created event.
For ease in filtering, your comments are generated as a special type of operator-added event that can
be selected as a sort criterion when events are displayed.

Print or display a report on request
Introduction
What Are Reports
Reports extract information from the server database. Reports may be requested and printed on
demand, or scheduled to be automatically generated at pre-defined times. Reports can be sent to
printers or to Operator Station displays. Experion PKS can produce both.
Main Idea
Standard Reports, which are preformatted reports provided with Experion PKS, contain
information about alarms, events, points, and so on.
Custom Reports can contain almost any kind of information stored in the server database.
You can either request reports when you need them or schedule Experion PKS to automatically
produce reports at pre-defined times.
Producing Reports
Reports summarize historical information in many useful ways. For example, one report may
consist of graphs of system-critical values over the past week, whereas another report may list
equipment due for service.
All reports need to be requested, either manually or automatically. Requesting a report generates a
new version using the latest data.
Depending on how a report is configured, printed, or saved, it can be viewed on screen or used by
another program. If the report is designed to be viewed on screen, you need to call it up after
generating it
For Alarm, Event and Message Summaries, you can use the Print As Report feature to produce a
printed report containing all, or a range of, the summary information within the display.
TIP
If you want a printout as a snapshot of what is shown
in Station, see Printing Station Information.
