1 HMI Overview

The HMI utilizes the Rockwell FactoryTalk View SE (version 8.2) software suite as a local standalone application. The FTView local application runs on (2) desktop machines running Windows 7 Professional.

The clients have the ability to view the data logged history (historical data) and any of the alarm events logged by the server.

*NOTE: This document is in draft form and is intended to provide an overview of the screen layout, colors and functionality.

2 GRAPHIC DISPLAYS

This section will describe the various displays, operator controls, and information that are presented to the Operator. Sequencing and control operation is described in detail in document ACGAL020S000002 System Design Specification).

2.1 COMMON DISPLAY ELEMENTS

The HMI incorporates two types of screens: Primary and Secondary. A Primary screen is a screen that displays data and control elements used for monitoring and control of the unit or a specific system. It is displayed as a large (full-screen) window. A Secondary screen is a screen that displays specific information on the state of the unit or commands to execute a specific action.

Common elements are displayed on all Primary HMI screens using a standard template.

• Information Bar (major components)

• Navigation Bar

• Alarm Banner (latest Alarm displayed)

• Main Screen

2.1.1 Information Bar

This contains consistent and key information for each individual Unit and is located at the top of all displays. It also includes such state information such as speed, valve demand, engine status, etc.

2.1.2 Navigation Bar

This provides the Operator with the ability to navigate to other displays. Additionally there are icons at the bottom that allow the operator to open trend files, display the alarm Summary and History pages, Acknowledge All Alarms.

2.1.3 Alarm Banner

The Alarm Banner is anchored to the bottom of the screen. It displays the five most recent alarm messages. These messages may advise alarm or shutdown conditions. When an alarm condition is first detected a new message is added to the top of the cumulative list of alarms. The message will have an associated date of occurrence, time of occurrence, acknowledge time, severity class, and alarm state. Upon initial annunciation, the message will blink to advise the operator of the new alarm. The message will continue to blink (shutdowns are RED, alarms are YELLOW, hardware alarms are ORANGE, events are BLUE) until the “Alarm Acknowledge” pushbutton is pressed (either from the Navigation Bar or Alarms display), confirming that the operator has recognized the alarm condition. Acknowledged alarms that are still active will be displayed in solid text. This is only applicable to the alarms, hardware alarms and shutdowns. However, for the system alarms, the operator has to go to the alarm summary screen, right click on the system alarm and select Ack from there.

An alarm message cannot be removed from the summary display until the condition which caused the initial annunciation is cleared and the alarm has been acknowledged. All shutdown conditions are latched in the PLC and the operator must press the “Reset Shutdowns” pushbutton (on the Navigation Bar or the Alarm Summary screen) to clear listed messages of their latched state.

2.2 DISPLAY SCREENS

This section will cover the screens displayed in the Main Screen area of the display.

2.2.1 Overview

The package overview displays the summary of the entire site. All five units are displayed with critical operating parameters. Further detailed information is obtained from the specific screen for that unit. Data that is displayed are as follows: temperatures, generator, unit status, and vibration..

2.2.2 Unit Fuel Screens

The unit fuel screens are the primary display for monitoring the specific unit parameters. Data that is displayed are as follows: turbine start sequence speed and temp switches, governor control status, turbine status, fuel status, and generator information.

These screens are to be used when starting a unit. Gauges provide quick visuals for key control parameters. Below the gauges are other important parameters and status information such as individual analogs, which control loop is in control and fuel being operated on. The speed and temperature switches on the left will change color as the turbine accelerates. Switches will be green above the switch value and red below the value.

On the upper right, AVR control mode selections are be made from this page. NOTE: Selections and adjustments to the AVR are then made from the Main Control Board. For example, when VAR-PF control is enabled, the selection between VAR or PF is determined by the position of the VAR/PF selector on the Main Control Board.

2.2.3 Trend Screen

The Trending screen has several default trends configured for viewing historical data. The default trends can be modified and saved. The screen also allows a user to create their own custom trends and save them via templates. Historical data is stored for 3 months on the C:\DLGLOG folder before old files are automatically erased and new ones are created.

2.2.4 Alarm Summary Screen

Displayed in this screen are all the alarms as it pertains to the turbine type and common systems.

The alarms are displayed here in rows; the information for each is grouped into four columns: 1) Alarm In Time 2) Acknowledge Time, 3) Alarm Name, and 4) Message. The first two columns contain icons that indicate the severity and the state of the alarm.

The “Alarm Time” is formatted: MM/DD/YYYY hh:mm:ss.msec AM/PM. The time stamp is based on the PLC clock.

The “Alarm Name” is formatted: [<UnitID>_<Alarm Number>]. With this format, a link is provided into the PLC logic. For example the alarm “[TCS_U1]SD_033” refers to Unit 1 shutdown number 033. Locating the shutdown 033 for the PLC type turbine in the PLC logic will provide a starting point in the logic to trace the alarm back to the point at which it enters the hardware I/O.
