Then , thelogs contain more than 100,000 sample of several data and I think it took large capacity of memory space. I want save the data in PG memory. At last I need to do it in realtime.

If it's quite big - try reading it with SCADA (has trends already), OPC protocol (can use SIMATIC NET), Prodave Library+ self-developed programm or CommandInterface (didn't have a precise look on that thing, but it must be possible). If time interval is relatively small - you need some special hardware.

Run the software on your PG (Siemens does allow it to run without licence, but you will get popup messages) Afterwards, you can check the log file for all data
