This module provides students with an introduction to advanced PLC programming languages which are widely used in industrial automation. In addition to graphical languages such as Sequential Function Chart (SFC) and Function Block Diagram (FBD), text-based languages such as Structured Text (ST) and Instruction List (IL) are also presented. Numerous programming examples are discussed using real-world applications and problem-solving techniques. This module also provides an overview of the RSLogix 5000 programming language and controller organizer, including tagnames, alias tags, and various editors (ST, FBD, SFC, etc.).

Learning Outcomes:
