Read full description

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.

ReceptionRating · Positive reviews · Number of ratings

Electrical Calculator lite holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: Electrical Calculator lite has 578 ratings behind it against 59, so its average is the more settled of the two. Written reviews complicate that: 39% of Electrical Calculator lite's written reviews are positive against 75% of PLC Simulator, PLC Trainer's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 months. Both last shipped on October 24, 2026.
