This program is unique in it's ability to test an electrical circuit. Now the complete circuit can be tested from the three phase power components to the control circuit. The built-in symbol libraries of over 600 symbols makes the creation of your diagrams fast and easy. Diagrams of over 300 rungs may be created in this version. The built-in symbol editor allows you to create your own custom symbols. Once designed, any circuit can then be Virtually Energized and operated on your computer monitor. The circuit will perform the same as a hard wired electrical circuit. The design can be edited and re-tested saving valuable time when it comes to hard wiring circuits and trouble-shooting scenarios. Automatic legends and borders allow you to make professional looking diagrams quickly. You can print your ladder diagrams out on your choice of any printer or plotter that Windows supports. The diagram may be saved to your hard drive or a floppy disk for easy reference or modification. You can also save images from within The Constructor program as bitmap files. The bitmap files can then be used for printing or imported into other programs.
