1.1. HMI/SCADA Systems_____________________________________

A. SCADA Functionality - Managing and Controlling the Process

In order to manage a process effectively, a solution is needed to provide a realistic

view of the process and the ability to manage and controlthat process

- a Supervisory Control and Data Acquisition (SCADA) system providesthis ability

Todays SCADA systems combine a number of technologies to provide securedata and control over various communications mediums

The SCADA software runs on a personal computer and may be a stand alone

system or a collection of PCs providing the needed functionality

SCADA systems typically maintain a database of last known values of the fielddevices

The SCADA system will gather and record data and provide the ability to displaythat data promptly to the operator

Some of the benefits of implementing a SCADA system includes an increase inproductivity, increase in quality and reduce overall operating costs

B. HMI Functionality - Visualizing the Process

The operator will need an intuitive and logical interface for process visualization

- aHuman Machine Interface (HMI) provides this ability

Some of the types of data the operator may want to view include real-time values,alarms, charts/trends, and reports

The HMI interface typically is in the form of graphics which will include

specialized capabilities to present the various types of data to the operator

Developing the HMI will include incorporating, ActiveX controls, Visual Basicfor Applications (VBA), Key Macros, Charts and more

1.2. HMI/SCADA Features_____________________________________

A. HMI/SCADA System Features

HMI/SCADA systems such as iFIX provide the ability to quickly develop

systems incorporating open industry standards and technology

- COM/DCOM

- OPC

- TCP/IP

- SQL/ODBC

- VBA

- ActiveX

The HMI/SCADA system provides the ability to communicate and acquire data

from many types of data sources using various communication methods

- TCP/IP

- COM/DCOM

- OPC

- Serial

- Proprietary connections

- Software interfaces (such as RSLinx)

The HMI/SCADA system will provide powerful functionality to manage the data

- Data Monitoring

- Data Distribution and Sharing

- Alarming

- Reporting

- Real Time Trending

- Historical Trending

- Data Protection and Security

1.3. HMI/SCADA Development_________________________________

A. Preparing to Develop an HMI/SCADA

First, a thorough understanding of the process to ensure all the process

information needed is available

Next, identify specific information

- PLC / Device definitions and addresses

communication methods used

memory addresses to access

types of data to access

- communication information for other data to be accessed, such as:

OPC Server information (including Group and Data Item names)

Relational Database Data Source Names

- number of nodes (PCs) that make up the HMI/SCADA system

non iFIX nodes such as Servers

iFIX nodes such as SCADA Servers, Clients, Remote Clients

- SCADA and Clients connectivity (TCP/IP, NetBIOS, etc.)

- software to be loaded onto each PC

include additional software such as Driver software

Once all the pertinent information is identified, the actual HMI/SCADAdevelopment can begin

B. Developing an HMI/SCADA in iFIX

A typical development process includes:

- installing the software

- basic system configuration

- configuring the Drivers

- building a Process Database

- creating graphics

- incorporating specialized functionality

alarming, security, trending, reporting, etc.

- add additional features, such as Visual Basic, C++, VBA, 3rd

party

applications, etc.

1.3. HMI/SCADA Development_________________________________

C. Before developing with iFIX, the following areas of iFIX should be understood:

Software installation

- include the appropriate hardware keys

- development versus runtime keys

Process Database development

- Tag types to be used (Analog, Digital, etc.)

- Tag naming convention

Control

- will control exist in iFIX (typically in PLC)

- iFIX has tags that can provide control Alarming

- use iFIX alarming or alarm in PLC or both

- alarm thresholds

- alarm destinations (report, view, store, etc.)

Security

- how to implement and maintain iFIX security

Types of data the operator needs to view

- real time values, alarms, trending, reports, etc.

Specialized functionality

- custom Database Blocks, custom applications (C++, VB or VBA)

Data storage

- Historical

- Relational Database
