Hi,

I attached here a very simple sample program with Data Logging.

As didactical propose, I just call the relative blocks and mount a Watch Table to the manual command. The block FB1 is used just to evaluate diagnose, it has no influence on the data log functions.

I suggest the follow sequence of commands in the Watch Table:
1 – Set a size for the data loggin: “Nr_Records”=10
2 – Create a File: “Cammand_Create”=1, and after “Cammand_Create”=0
3 – Give values for the logged variables, for example: “Data_Block_1”.Data.Int1 = 123; “Data_Block_1”.Data.real1=4,56;
4 – Write the open values to the File: “Cammand_Write”=1, and after “Cammand_Write”=0Repeat the steps 3 (with different values) and 4, so many times you wish
5 – Open the Internet Browser and give the Ethernet address of the PLC as Address (10.100.120.3).
6 – Browse in Data Logs, and click in Download Icon

Note: this sample program was made with STEP 7 V11 SP1 upd1.
