5.2.1 The Function Block Diagram (FBD) Window

The Function Block Diagram (FBD) window is used for programming of the α and α2 series
programmable controllers.
The FBD window is where you will do most of your programming. From the FBD window you
can create a program, simulate the program's operation, download and then monitor the
program running on the controller.

Creating a program

• Choose a function or logic block for your program
• Set parameters for the block by double clicking on the block
• Connect the blocks in the correct sequence using the Wiring Tool

Simulating a program

• Set the inputs and watch how your program will change the outputs. Simulation mode lets
you do this without connecting to a controller. This is a great way to prototype a program.

Monitoring a program

• Run your program on the controller while connected to your PC. You can set the inputs in
software and see the results in real life. This is a great way to prototype a program.
