A Controller fault is indicated when the red E LED is blinking. In this state, the node LEDs (O1, O2, R3, R4, and Q5) will blink the actual error code as two separate binary numbers followed by a 3-second pause (all node LEDs off, 0000). This sequence repeats as long as the error state persists. Open the GMD (General Message Display) for an actual readout of the error code in hexadecimal.

Refer to the Ovation Error Codes Reference manual for information on the error codes.


Ovation Local I/O Panel (ROP)

Controller I/O Module Address Format

Addressing Format

The logical I/O address is composed of three numbers (four when remote I/O is used) separated

by decimal points in the following format.

D = Device number assigned to the I/O device (1-5).

N = Node number (only used for remote I/O; 1 through 8)

B = Ovation Branch (1 through 8) or Q-Line Crate (1 through 4).

S = Slot where module is configured (1 through 8 for Ovation I/O; 1 through 12 for Q-Line

I/O)

See examples on the following pages.

I/O Module LEDs

Information about I/O module LEDs are located in the Ovation I/O Reference manual.

Module 3 Objectives

Demonstrate Basic Operator Functions


1. ACCESS a graphic window and perform basic operator tasks

2. IDENTIFY the Ovation Record types

3. ACCESS an Alarm window and perform basic operator tasks

4. ACCESS a Point Information screen and perform basic operator and technician

tasks

5. SEARCH for specific point parameters using Point Information

6. ACCESS a Trend window and perform prescribed tasks

7. ACCESS a Point Review window, perform a specific search, and modify points

attributes


Ovation Record Types (with examples, if applicable)

Record Type Abbr. Monitor status of: Example Name break down

Drop record DU Ovation MMI’s & Controllers DROP200, DROP1

Node record RN Power supplies / remote nodes D002P1 Drop2Device1 D001P2N4 Drop1Device2Node 4

Module rec. RM Configured I/O modules D001P1B4L3 Drop1PCI1Branch4Slot3

♦Digital LD Digital points, two possible values (1 or 0), software and hard wired.

♦Analog LA Points with a range of values. (0-100%, 0-3000 PSIG, etc.)

♦Packed LP 16 digital bits that are treated as a single point or “word”.

Long control LC Long Control or Algorithm points are created while building and modifying control sheets using Ovation Control Builder. See Control Builder Users Guide for more information on algorithm point names.

♦ Note: There are no “standard” Emerson Process Control Power & Water Solutions

point names for these record types and therefore, no examples are given.


Point Information Search Window

Use the left window to define the level you want to search. Searches can be done at

the Drop, Unit, or Network level.

Use the right window, via the “Filter” pull down menu on the Find Points window, to

narrow the search using wild cards and/or pull down options.

* = Point Information multi-character wild card

? = Point Information single character wild card

Wild cards can be

used in name, alias,

and description fields


Point Review Window

Point Review allows the Ovation user to see the current status and checking

configuration for points. The user can specify the parameters they want to search and

then have the Point Review tool help them find points meeting the specified criteria.

Once the search is complete, the user has the option of modifying attributes on any or

all points. (See guidelines on page 16.)

Point Review Filter Window

Common filter search items, as shown below, are Alarm Check Removed, Limit Check Removed, Scan Removed, Test Mode, and Entered Values.

Point Review Modify Attributes Window

Using Point Review (see screen captures from previous pages)

1. Open Point Review.

2. Select the “Filter” button on the toolbar.

3. Check the items you want to search for (see example on p. 15)

4. Click OK.

5. Click the “GO” button on the toolbar. After the search is complete, points meeting

any of the search criteria will be on the screen.

6. NOTE: Proceed only if you are sure of your actions.

7. Select any points you wish to modify attributes.

8. Click the “MODIFY POINT ATTRIBUTES” button on the toolbar.

9. Select attributes you want to modify on ALL selected points. Click OK

10. The Point Review window will update status as point attributes are changed

Module 4 Objectives

Discuss the Hierarchy and Right Click Functions within the Ovation

Developer Studio


1. ACCESS the Ovation Developer Studio

2. RESIZE the Overview, Workpad, and Workspace windows in the Developer Studio

3. USE the right click menu in the Developer Studio to Load controllers

4. UNDERSTAND recommendations when Loading Controllers

5. UNDERSTAND data movement in an Ovation system


Resizing Ovation Developer Studio Windows

Make these common changes and use these guidelines for building and modifying ALL

points in class this week.

LOCATIONS Hint: Watch for the cursor to change to “bars”


Drop Load Recommendations

• Read all bullets prior to loading controllers.

• Use the Developer Studio to perform a Consistency Check on the controller pair

prior to actually loading the controllers. Fix all items that are listed that may

cause problems during / after the Load.

• Use the Developer Studio to perform a Reconcile on the controller prior to

actually loading the controllers. ONLY RECONCILE THE CHANGES YOU

KNOW ARE VALID. IF YOU ARE NOT SURE ASK OTHERS.

• Load the controller in control first. DO NOT ASSUME! Use your system status

graphic to verify which controller is in control and back up.

• Only Load the backup controller after you verify proper operation of the points

and controls.

• Note that the Drop Details graphic indicates Powertools and/or Partner

mismatches. Some customer system status graphics may also reflect mismatch

conditions.

• Drop Load after making a relatively small number of changes – Don’t Stockpile

• If possible only induce failovers when plant is running at steady state conditions

or when the unit is offline.

• Make sure you have the authority and permission to Drop Load when the unit is

in operation.

well as put the point into calibrate mode. Take any precautions necessary to

prevent problems!

Module 8 Objectives

Create and Test Packed Points


1. MODIFY existing packed points in the Ovation Developer Studio

2. CREATE new packed points in the Ovation Developer Studio

3. UNDERSTAND applications for packed points


Control Application for Packed Point

Common Uses of Packed Points include:

• Mode words for control algorithms

• Status feedback for motors, pumps, valves, etc

• Permissives for starting, stopping, and controlling field devices

Output of a PACK16 algorithm is a packed point. Each bit represents the status of a digital input point. The PBPT output of control algorithms are packed points.
