    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

    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

    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.

    - 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.
