Create log files
The data logged with the DL data logger manufacturer function block is stored on the
card in a folder. The folder is named as entered in Programming view/Data logger para-
meter tab under the folder name of the log session.
The data in the recording is binary-encoded and cannot be read with standard Windows
PC tools. You can instead read it in easySoft 7, where you can view the logs on the card
and export them to Excel. To do this, click on Project menu/Card.../Data logger logs/icon
Card = PC button. In the process, the binary data of a log are converted to a *.csv
format, compiled and stored in a file. They can be read and edited in Excel.
Please keep in mind that only one folder can be created for each log ses-
sion, even if the number of files per log session is selected as greater than
1 and several binary files are also stored accordingly.
Task: Any time the device button P1 is pressed, this should be logged. A total of 3 log
files with 3 data sets each should be logged. No further logging will occur afterwards.
To do so, follow the steps below:
Switch to Programming view.
Place a function block DL in the workspace.
From the catalog, drag a N/O to the function block input DL01_T1.
In the Contact tab, configure the operand as P device button
