This document discusses best practices for learning SCADA systems. It recommends a three phase approach: 1) a strong foundation in PLC and SCADA basics, 2) vendor-specific SCADA training, and 3) more advanced SCADA topics. For phase one, it outlines prerequisites like PLC basics and computer literacy. It also recommends getting hands-on experience installing and modifying real SCADA software. Phase two involves training from SCADA software vendors. Phase three covers more specialized topics like process control, networking, and programming. The overall goal is to learn SCADA systems thoroughly through a structured, multi-step process.
