The paper provides a brief explanation of the automation and SCADA industry along with networking schemes. Protocols as a crucial part of the system are explored in depth. In addition, commonly used protocols and standards are mentioned concisely. The newest invention of the IEC standards committee, known as IEC 61850, is also introduced. IEC 61850 and UCA have promising advantages over other protocols and will greatly change SCADA systems today. Also, a general guideline is provided for protocols, which is then used to create a comparison chart for them.
