SCADA Vantage display unanswered alarm list on the lower right corner of a standard screen. SCADA system also adopts main screen map display method. You can open a picture

by press a page button in which alarm message collection is included. SCADA Vantage

will arrange the order of alarm message per priority and time sequencing. When alarm

occurs to one of the alarm collection, the relevant light among the alarm collection will flash until it has been responded. When there is alarm being neglected, an aural signal may be produced by SCADA Vantage to warn the operator. The selection of sound style will depend on your company’s preference. Response to any alarm can be done by placing the cursor on the alarm point and double click mouse. You can rearrange the order of alarms within the alarm collection by click the item within the title bar.

Collection of operator alarm

 

Operator alarm is a type of single or repeated alarm that can be set by operator. This

type of alarm can contain information defined by customer. Operator alarm is similar to an alarm clock, which means alarm appears in special time span and with special information. You can open a picture relating to this type of alarm by click relevant command button.

Click “ ”button to increase new operator alarm. New operator alarm dialog box will appear in front of you, as shown below:

Enter operator alarm title and click button, a new page relating to features and configuration of operator alarm will appear, as shown below:

You can also open this page by clicking relevant alarm in operator alarm sheet. In this page, you can obtain information such as description on operator alarm, comments, schedule type and re-schedule type. Activation of alignment of activity means daily starting time

for an alarm assigned to a designated activity. Activation interval is effective only when

timing style is defined as Interval or Interval offset. Activation interval is defined as the time span from activation of an alarm to alarm signal being sent out by the alarm device. Operator alarm feature is used for defining alarm zone and priority. Operator alarm zone and priority can be determined by clicking one of options appeared on the screen. Operator alarm information is described as displayed information when an alarm really occurs.

Features of tendency chart

Although all real-time system and SCADA system boast tendency chart function, SCADA Vantage system has obvious advantage over other systems.

Trend diagram basing on real-time data can be saved, whatever ways used by you to visit it.

The automatic online archiving and reappearing function for blocks of tendency chart

allow customer visit data tendency chart representing a long time.

1.1.6 Application management system for customer station(CAM)

This software is responsible for the management of client station upgrading.

When the client stations of SCADA Vantage system are connected with server, CAM

Will check software of each client to identify whether it is the newest version.

It will perform automatic upgrading in case that the software is not the newest version.

In case that software upgrading is needed for client, CAM can download necessary component to client station and perform upgrading. Allowing system administrator save new software inside CAM and automatic upgrading client station make software upgrading easier. At the same time, problems stemmed from upgrading can be reduced.

Flexible framework

SCADA Vantage system can select any operation mode from following:

Single computer system without redundant function

Redundant system which can perform automatic switch in case of malfunction and

possess warm standby function.

Hierarchy server and point to point, peer to peer server

Automatic

Visit via internet

Single computer system is mainly applied in middle and small system. Short time rest is allowed for this type of system.

Redundant system with warm standby function is applied in main control center where

operating condition is very strict. Rest is not allowed for system in main control center.

Hierarchy server is applied where database is located at different fields, so as to minimize influence stemmed from out of service of computer. But there must be

a real-time host database for use of inquiry and visit. The upgrading of host database

is done via field database.

Point to point server is used for off-line warm backup. Compared with host server, off-line server is placed at different place or places far away and frequency of data refreshing is very low. Once system at main control center is taken out of service

by catastrophe, off-line backup system will take over

Real-time database and history database can be visited by table.

Human Machine Interface(HMI)

IndustrialIT SCADAVantage is applied as HMI monitoring software and used by SCADA system. It is used for equipment control, monitoring process data, display of data/state/alarm, recording of alarm/incident, production of report form, and so on.

Operator station receives data from SCADA system server without interrupt and presents them to local HMI to finish command and data input at local station level. With it you can provide local station CRT with graph and form and obtain data, alarm message

,record, graph, real-time tendency line, history tendency line as well as history data.

The application of history tendency can provide each recorded variable with selectable sample cycle, dead zone and time cycle.

IndustrialIT SCADAVantage：

The picture style provided by IndustrialIT SCADAVantage include:

Provide local SCS with operation interface. Provide each unit in local station with

graph or table display function. With a series of graph and table display, as well as printed incident record and report, the operator can secure status messages on station and unit in the station through color(CRT display) and value.

Picture selection is done through menu selection, and with one touch you can switch from one picture to another one. The initial picture will display panorama of station and field, including main equipment and buildings. Each picture at lower level will

display a smaller area of the field and provide more detailed process information compared with that contained in the last one.

With the aid of keyboard and mouse, operator can modify operation parameter of a station, turn off one pump unit, switch on/off valves, change set-point for a station, change alarm threshold value and change station operation mode.

There is dynamic zone in the picture that is reserved for inputting data and command.

Operator can input relevant data and command in this zone to change system parameter, turn on/turn off pump unit and change operation mode. When a new picture is selected,

the way for data entry is not selected automatically. At first, place cursor at place where data to be entered (by the time, the zone will be lightened). Then, you can input desired data or select command or data from dialog box. At last, you can click

acceptbutton in the picture ( or press return key) to receive new data or command.

In case that what is inputted has not been accepted in designated time, the command or data will be restored. It can accept various data, including transfinite testing data and preference upgrading data. System will not accept new data or command until

Return key or accept button is pressed. Data or command inputted can be edited before being accepted. At the same time, any inputted data or command will be saved in alarm/incident printer and which is displayed in alarm/incident collection picture.
