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

1.3. 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.
