if you not have stored before the program in SD card, during the first phase of commissioning, you can not read from PLC the program.
Please note at the follow adress the same question and the answer
Open Codesys and go to file and select open, In the Open Dialog box you can see the option called open project from PLC (reffer attached snap Shot) than select your controller type and press OK.
If you have AC500 target files and correct communication setting than you can upload the pogram into your Laptop.
