![]() To prepare for the lesson, I recommend that you use my affiliate link to download Factory IO and start your 30 day free trial. We'll sort that out in tomorrow's lesson when we connect the Micro800 Simulator to a Factory IO model and control a simulated process in a virtual warehouse. It is not clear how this program would control a physical process. ![]() I hope this lesson has helped you to understand how Ladder Diagram programs work in more detail.Įven though we have tested our PLC program, the end result is still very abstract. We saw how to download our project to a simulated PLC, how to force input values to test our logic, and how to monitor output values to verify that our logic is working correctly. In this lesson, we learned how to simulate a Micro800 PLC to test our PLC project. What happens when you force the input DI 01 or DI 02 to True? Wrap Up ChallengeĬontinue testing the behaviour of the PLC program by forcing the other inputs. We can see that the Direct Input instruction is evaluating to False since the input DI 00 is False.Įven though the Direct Contact instruction is evaluating to False, there is still logical continuity in our rung because we have used a seal-in circuit design pattern. In Connected Components Workbench, launch the Micro800 Simulator by clicking on Tools > Micro800 Simulator (1) or by clicking on the Micro800 Simulator button on the Toolbar (2). If you don't have the project from yesterday's lesson, you can grab the required files from the PLC Bootcamp Facebook group which you can join using this link. This lesson builds on the PLC project that we created in yesterday's lesson. Test our logic by monitoring the program while forcing the PLC's physical inputsīy the end of the lesson, you will know how to debug your program when it doesn't do what you expect it to do (and trust me, this happens a lot when you are writing PLC programs!).Download our PLC program to the simulated PLC.In the next few sections, we will learn how to ![]() Today, we are going to focus on testing the PLC program that we created yesterday using the Micro800 simulator. ![]() Welcome back to another lesson in PLC Bootcamp, a free course designed to teach you everything you need to know to be a proficient PLC programmer. ![]()
