Programmable Logic Controllers (PLC) are the workhorse of Industrial Control systems. This session will cover the PLC system and dive into I/O modules used to interface with sensors/actuators on the factory floor. I/O modules must meet stringent electrical specifications and can be classified into current, voltage and digital input/output types. We will explore the challenges that designers face in conditioning and converting these signals and touch on solutions to address these challenges. These I/O modules communicate over industrial fieldbuses. Therefore, we will also briefly cover processors and interface solutions for communication fieldbuses in Industrial Automation
