7 Operator Control

iPower provides a complete environment for safe and efficient operator control, making it ideal

for operator-intensive SCADA applications. No programming or special configuration is required

to deliver the following functionality:

Control Dialog

Click on a device to pop-up a control dialog that is specific to that type of device. The operator is

presented with a clear and consistent control interface.

Select Before Operate

The Operate button is only highlighted once a specific control command has been chosen,

reducing the chance of accidental control.

Check Before Operate

“Are you sure” prompts operators for a last check before issuing a control. This final check can

be disabled for those that don’t require the extra safety step.

Alarm Control Failures

An alarm is raised if a control fails to complete after a user-defined time.

Suppress Alarms for Operator-initiated Changes

Prevents the generation of spurious alarms, when an operator deliberately controls a device to

a normally alarmed state. An example is tripping a circuit breaker open.

Simultaneous Control Prevention

Once the first operator opens the control dialog, any other operators trying to do the same are

advised who has control of the device and on which workstation. This prevents multiple users

on different computers from controlling the same device at the same time.

Dialog Timeout

The control dialog automatically closes if idle for a user-defined time. This releases the device

for control by other operators, thereby preventing any unintentional disabling of control.

iFIX iPower 5.5-5.8 docv2.3.docx

8 Control Tag-out / Lock-out

A control tag is a software lock, applied by operators, that prevents operation of a device.

• Prevents both manual (operator) controls and controls initiated by SCADA automation

• Attempts to control a tagged device cause the tag information to be displayed

• Operators select from up to 50 user-defined control tag types when tagging a device

• Users can define their default tag type

• Operators can add a free-format, unlimited-length tag reason message

• Tag presence is shown by Attribute Indicators

• Adding and removing tags is recorded in the Events list

• Control Tag List displays all tags in a system

• View / remove tags from any display of the block, or from Control Tag lists

• *Control Tag list in a Device display, only displays Control Tags for that single device

*Available in iFIX iPower 5.8

iFIX iPower - Product Overview 16 July, 2013 Page 16 of 32

iFIX iPower 5.5-5.8 docv2.3.docx

9 Information Tag

An information tag provides an advisory or warning to Operators. When an operator clicks on a

block, any information tags are displayed to the Operator, before the Operator can control the

device. That is, the Information Tag acts as a pre-control warning, typically of an unusual

condition. However unlike a control tag, an information tag does not prevent the operator

completing the control.

• Attempts to control a tagged device cause the Information Tag to be displayed

• Both Information Tags and Control Tags can be applied to one device.

• When both tag types are present, the Control Tag text message is displayed in preference to

the Information Tag message.

• Operators select from up to 50 user-defined Information Tag types when tagging a device

• Users can define their default tag type

• Operators can add a free-format, unlimited-length tag reason messages

• Tag presence is shown by Attribute Indicators

• Adding and removing tags is recorded in the Events list

• The Information Tag list displays all tags in a system

• *An Information Tag list in a Device display only displays Information Tags for that device

• View / remove tags from any display of the block, or from Information Tag lists

*Available in iFIX iPower 5.8 and later

iFIX iPower 5.5-5.8 docv2.3.docx

10 Manual Overwrite

Manual Overwrite enables operators to write a current value for a block into the SCADA

database, and have the SCADA ignore telemetered readings for that block. It is typically used

when a transducer is not yet installed, is faulty, or has been removed for servicing. Manual

Overwrite is also known as ‘Local Force’

Fig: Operator dialog for Manual Overwrite

• Manual Overwrite is available for both analog and single-bit digital values

• Manual Overwrite presence is shown by Attribute Indicators

• Manual Overwrite values are displayed in an identifiable Manual Overwrite color

• Adding and removing a Manual Overwrite is recorded in the Events list

• Manual Overwrite List displays all blocks in a system where a Manual Overwrite is in place

• Operators can view / remove Manual Overwrite blocks from any display of the block or from

the Manual Overwrite list

• *A Device Manual Overwrite list displays manually overwritten blocks in that single device

14 Notes

iPower Notes facilitates operators sharing information about devices or locations. iPower can

be configured to automatically provide a unique note for each main device (say a pump or a

transformer). Notes can also be added to pictures, so adding a note to a substation/pump-

station picture provides a note about that substation/pump-station.

Features

• Per device, e.g. circuit breaker, pump, generator, motor, transformer

• Per picture, e.g. substation picture, pump station-picture, well-head picture

• A Secure text editor, Notes does not provide access to computer hard drives through ‘Save

‘As’

• Automatic Notes history: Each ‘Save’ keeps the previous revisions accessible through Notes

History.

List Configuration

All iPower Lists provide a consistent user experience. The function of any list is set during

configuration, but can also be changed on the fly at runtime. So for example an events list can

become and list of disabled alarms, then a Control tag list, and so on. The List configuration

tool is accessed directly from within the Workspace in configure mode, from the “iPowerTools”

toolbar:

Adding a list is simply a case of dropping it into the iFIX picture, dragging it to resize and position

it, then picking the functions required:
