Downloading and Debugging the Program

7.1 Establishing an Online Connection
Using the supplied project "GS-LAD_Example" or the "Getting Started" project you
have created and a simple test configuration, we will show you how to download
the program to the programmable logic controller (PLC) and then debug it.
You should have:
•
Configured the hardware for the "Getting Started" project (see Chapter 6)
•
Set up the hardware according to the installation manual
Example of a series circuit (AND function):
Output Q 4.0 is not to light up (diode Q 4.0 lights up on the digital output module)
unless both Key I 0.1 and Key I 0.2 are pressed. Set up the test configuration
below using wires and your CPU.
