7 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.
