CEC – Building Your Own Internet Connected PLC

Programmable Logic Controllers (PLC’s) are the foundation for manufacturing and the industrial IoT. Developers are probably used to purchasing off-the-shelf PLC controllers, but it is possible to build a simple low-cost PLC controller using microcontroller components. In this course, we will explore PLC fundamentals and how we can create our own internet connected PLC controller using an STM32 microcontroller.

Session 1 – PLC Fundamentals

In this session, attendees will learn about programmable logic controllers (PLC’s) and the role that they play in the industrial IoT. We will explore when and where PLC’s can be used along with the typical PLC use case.  We will also begin a basic discussion about how to control a PLC through ladder Logic.

Session 2 – Designing a PLC

This session will walk developers through the steps necessary to design an internet connected PLC. We will select the major hardware and software components that will be used to assemble the PLC. We will explore how to perform an objective analysis using a KT matrix. Attendees will walk away with an increased knowledge on how to properly select components for an application.

Session 3 – PLC Software Design Part 1

In this session, attendees will examine the underlying details on how to create an internet connected PLC. We will setup a software project and the major library components necessary to start assembling the PLC. We will examine the low-level drivers and middleware necessary to get the PLC up and running.

Session 5 – PLC Application Design

In this session we will setup a test PLC application that controls several I/O devices over the internet through a mobile device. Developers will get to design their very own PLC application. We will then review the major points that developers need to take-a-way and implement a PLC in their development cycle.
