1. Easy and convenient program creation and editing.
2. Programs can be saved on a computer and accessed at any time. programs
   can also be upload from the controller and then edited.
3. Enables users to print programs for reference and review.
4. The Simulation Mode allows users to virtually run and test the program before it is loaded to the controller.
5. Real-time communication allows the user to monitor the EDS PLR operation during RUN mode.

FBD (function block diagrams) Programming
Easy to use MS Windows based software that requires no prior experience or training
Program elements are placed on screen, with inputs on the left and outputs on the right. All that remains is to point and click predefined function blocks (timers, counters, logic blocks etc.) in between. Connecting it all together, or wiring, is drawn graphically by mouse click to build up the logic.
Function block parameters and characteristics can be set or edited by double clicking the block, a dedicated window then appears showing all possible options.
Once a program has been created a built in simulation function can be used to ease programming effort even further. Local testing of the program can be achieved separate from the controller eliminating any chance of actual malfunction or damage to the hardware.
Online monitoring and process visualization shows the real status of inputs/outputs and function blocks. The system sketch window is a separate area where a graphical image of the process can be built and control elements copied over from the main program. During monitoring the program elements will then be clearly associated with the actual process elements.
