Part 2: Understanding the network communication process between a PLC and the SCADA computer is important because there are a number of elements that need to be addressed, such as the language a computer speaks and the tools needed to streamline the process.

Journey to the center of the plant: SCADA systems and the big picture

Part 1: Having a clear understanding of how process information is flowing through an automation system managed by SCADA is a key skill for every instrumentation and control specialist whether they are responsible for the design, integration, installation, or maintenance of the system. This understanding can make the difference between a seamlessly integrated system and complete chaos.
