This app is designed to help anyone that is new to PLCs and wants to learn the basics of "How a PLC works" and PLAY with a simple simulator to experiment with some simple programming. The app consist of three main sections, "How a PLC works", "PLC Block Diagram" and the PLC Simulator. The PLC Simulator allows the beginner to learn simple programming skills with 3 timers, 2 counters, 6 compare instructions, 2 Binary outputs and 3 RES outputs. The user interface is very friendly. For first time users, there is an information icon that shows just how easy this app is to program. The NEW SAVE feature allows a user to start a program and come back to it at a later time. This app also helps people better understand the exam-off instruction -[/]-, the "Seal-In" or "Latching" logic, such as a motor start/stop circuit and much more. Enjoy the fast growing world of PLCs. My daughter found it very useful for her Mechatronics class. Try it, you will like it.
