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.

Command-Line Calculator (CLCalculator) provides the most fluid interface, especially if you are performing chained calculations i.e. multiple calculations that rely on the results of previous calculations. By providing a command-line interface, CLCalculator allows you to easily enter and view the history of your calculations. You focus on your calculations instead of being intimidated by myriad of buttons on a traditional calculator interface! In addition to performing basic calculations, CLCalculator provides an array of features such as: - Assign and reuse variables - Complex numbers - Number bases i.e. binary, octal, hexadecimal - Constants e.g. e, pi - String manipulation - Matrices - Unit conversion: in-built and user-defined (create your own units!) - Functions: in-built and user-defined (create your own functions!) - Arithmetic functions e.g. fraction, square root, rounding off, ceiling, floor, logarithm - Algebra functions e.g. derivative, simplify symbolic expressions, solve linear equations - Bitwise functions e.g. bitwise and, not, or, left and right shift - Combinatorics functions e.g. Bell, Catalan, Stirling numbers - Geometry functions - Logical functions e.g. and, not, or, xor - Probability functions e.g. combinations, permutations, factorial - Relational functions - Set functions e.g. cartesian product, intersection, union - Statistics functions e.g. mean, median, mode, standard deviation, variance - Trigonometry functions e.g. sin, cos, tan, cot, sinh, acos - and much more! The app also comes with a comprehensive in-built help system with plenty of examples. CLCalculator is powered by math.js (https://mathjs.org/)
