This book contains various applications of programmable logic controllers and SCADA designing of a plant. Nowadays, all human handled plants are being replaced by automatic control systems, thus called Automation. PLCs are accepted worldwide for easier access and better precision. In this book Rockwell PLCs are described and so is the SCADA design, which is also done by the RSView32 software, manufactured by Rockwell. It is one of the biggest names in the PLC software industry, being easy to use, control and modify. Some electrical drives, such as D.C drives and A.C drives, are also described in detail because the control part is done by the PLCs but the main plant is based on these electrical drives.

CHAPTER 3: SCADA DESIGN:
The SCADA Human Machine Interface (HMI) software provides a graphical representation of the RTU status and alarm history. The SCADA HMI software allows visualization of all process data and operator control over site equipment. Operational and environmental reports can be generated from the SCADA HMI system and summarized data can be stored in historical files of the SCADA HMI system.
SCADA HMI SOFTWARE System Overview, Trends, Alarms, Reports, Historical Data:
RSVIEW SCADA HMI SYSTEM FROM ROCKWELL SOFTWARE PROVIDES THE ABILITY TO:
- View facility-wide operationally-centric data.
- Capture, store and retrieve critical operational data with operator notes.
- View Trend data in real-time from "live" data or historical sources - Provide high system availability and data integrity.
- Preemptive critical alarm notification of operations and maintenance staff via text or voice paging system.
- Produce operational and regulatory report on regular intervals.
- Provide system-wide administration of security and log-on rights.
COMMUNICATION MEDIA:
Lease line modems, radio modems, cellular modems, frame relay, satellite, and microwave are all means of connecting RTUs to a central SCADA HMI system. Rockwell Automation RTUs connect to many Third Party devices to build a complete SCADA system. Rockwell Automation maintains a list of quality communication technology partners in our Encompass Partnering program. We have partnerships with some of the top names in the industry.
INTRODUCTION TO DESIGNING:
Whether describing Oil and Gas or Water Wastewater industries, today´s focus on the bottom line and reducing costs put Operators and Engineers under constant pressure to find ways to maximize efficiency.
As an Oil or Gas production or transportation company, you are under constant pressure to maximize production, meet increasingly demanding delivery schedules and reduce operating and maintenance costs while ensuring compliance with environmental regulations and secure operation.
As a Water Wastewater Supervisor, you are expected to ensure public health, protect your local environment, operate your system within budgetary constraints, and provide secure, uninterruptible wastewater collection and water distribution service to your customers. With increasing government regulations, increasing output and heighten security awareness, many have seen the need to install or upgrade Supervisory Control and Data Acquisition (SCADA) systems. The function of a SCADA system is to monitor, operate and control remote systems that are located over a large geographic area from a central location. Remote monitoring and control can provide data that can be used to significantly enhance operation efficiencies, reduce downtime, and increase security and counterterrorism measures. Other benefits of remote monitoring include better regulatory record keeping and reporting, remote trouble shooting to reduce downtime and increase repair efficiency, reduce time and travel labour cost, and improved capability to instantly alert operators of alarms and undesirable events. Rockwell Automation is a leader in providing high quality, off-the-shelf, hardware and software SCADA solutions for the water and wastewater and Oil & Gas industries. Built with open communication protocols like Ethernet, DF1, and Modbus and support for the most used SCADA protocols like DNP, BSAP and others, our PLC-based Remote Terminal Units (RTUs) offer multiple topology configurations:
- Point to Point.
- Point to Multi-point.
- Report by Exception.
- Broadcast.
- Store and Forward.
and are supportable by your maintenance staff or local systems integrator using ladder logic programming language. Visualizing and maintaining your system, and informing your operators from a central location is made easy with our RSView SCADA software which comes with I/O drivers to co
