regarding "timestamp"

Pegaia

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.

Good Morning fron France
Thank you verry much for this sample . It's working well without errors.

I would like to know a detail regarding "timestamp" of each record .

Does it possibloe to configure this telegramm? I have to add the HH:MM:SS:MS (mill-second).

Do I add manually "ms" like a data (var1,var2,..ms")?
The goal of my question is to create a management of alarm's into the CPU. So it is more important to have more accuracy, time in "seconde" isn't enough
That's the reason so it is necessary to have the ms into Time
Thank you for your help
