1: If you have Windows 2000 or Windows XP, I recommend the new USB adapter. 6ES7972-0CB20-0XA0

ALternatives are:
Serial adapter. 6ES7972-0CA23-0XA0 (slow speed !).
CP5512 PCMIA adapter 6GK1551-2AA00 (Windows 2000 or Windows XP only !).

2: When you are online, you can use the function "upload station to PG". That will copy everything from the PLC to the laptop. But there will be no symbols or comments !
