SCADA: Beginner's Guide
This book has detailed Project that explain the practical concept of PLC & SCADA Systems and it will be useful for Students, Technicians and design professionals.
SCADA is a system operating with coded signals over communication channels so as to provide control of remote equipment (using typically one communication channel per remote station). The supervisory system may be combined with a data acquisition system by adding the use of coded signals over communication channels to acquire information about the status of the remote equipment for display or for recording functions. It is a type of industrial control system (ICS). Industrial control systems are computer-based systems that monitor and control industrial processes that exist in the physical world. SCADA systems historically distinguish themselves from other ICS systems by being large-scale processes that can include multiple sites, and large distances.
Scada processes include industrial, infrastructure, and facility-based processes, as described Industrial processes include those of manufacturing, production, power generation, fabrication, and refining, and may run in continuous, batch, repetitive, or discrete modes. Infrastructure processes may be public or private, and include water treatment and distribution, wastewater collection and treatment, oil and gas pipelines, electrical power transmission and distribution, wind farms, civil defense siren systems, and large communication systems. Facility processes occur both in public facilities and private ones, including buildings, airports, ships, and space stations. They monitor and control heating, ventilation, and air conditioning systems (HVAC),
SCADA can be a great tool while working in an environment where operational duties need to be monitored electronical communication instead of locally. For example, an operator can position a valve to open or closed as desired through SCADA without leaving the control station or the computer. The SCADA system also allows to switch a pump or motor on or off and has the capability of putting motors on a Hand operating status, off, or Automatic. Hand would be referring to operate the equipment locally, and automatic would be scaling the equipment to be operated according to set points the operator instructs on a computer that can communicate with the equipment through SCADA.
Remote terminal units (RTUs) connect to sensors in the process and convert sensor signals to digital data. They have telemetry hardware capable of sending digital data to the supervisory system, as well as receiving digital commands from the supervisory system. RTUs often have embedded control capabilities such as ladder logic in order to accomplish boolean logic operations. Programmable logic controller (PLCs) connect to sensors in the process and converting sensor signals to digital data. PLCs have more sophisticated embedded control capabilities, typically one or more IEC 61131- 3 programming languages, than RTUs. PLCs do not have telemetry hardware, although this functionality is typically installed alongside them. PLCs are sometimes used in place of RTUs as field devices because they are more economical, versatile, flexible, and configurable.
This Guide explain the each topic with real time projects and case studies.
In the interest of continual further improvement, all readers of this book are invited to make contributions by way suggestions, ideas and constructive criticism.

Gods for beginners
This book is a good beginner book. The program would of been a lot better if it was labeled in the actual name of sensors.
