I am thinking about creating a User Defined Page where I want to put script written in Java Script. After clicking a button, the script would list all data logs from the webserver and download all of them one by one or as a ZIP file. I found ready made script in S7-1500 webserver manual, as pasted below (with description): Downloading of the DataLogs via JavaScript The following example shows how you can download DataLogs automatically by using JavaScript. Replace the URL of the example by the correct IP address of the interface of your CPU at this URL and use the appropriate transfer protocol (HTTP or HTTPS). <html> <head> <title>DataLog JavaScript Test</title> <script type="text/javascript" src="jquery- 1.12.4.min.js"></script> </head> <body> <h1>DataLog JavaScript Test</h1> <div><button id="load">Load DataLogs</button></div> <div><ul id="list"></ul></div> <script type="text/javascript"> $('#load').click(function(){ $.get('http://192.168.2.132/DataLogs', {'Action': 'LIST'}, function(data){ $('#list').empty(); $.each(data.split(/\r\n/), function(){ if (this.length == 0) continue; // I changed continue to return because it was throwing an error $('#list').append('<li><a href="http://192.168.2.132' + this + '">' + this + '</a></li>'); }); }); }); </script> </body> </html> Unfortunately the script does not work. First of all, I changed all necessary data like IP address or http/https prefix (to the same as in webserver settings in the CPU). When I try to run this script, I keep getting the "404 NOT FOUND" error. It lloks like the directory http://IP_Address/DataLogs does not exist. When I read the data log directory url from webserver and paste it to the script (it looks like http://IP_Address/Portal/Portal.mwsl?PrivNav=FileBrowser&Path=%2DataLogs), it returns an exception. I run the script on the UDP, tried with different versions of jQuery, different urls to the data log directory and nothing works fine. Maybe some of you have managed to do this kind of script or have different idea how to download many logs at once? Maybe someone have any ideas why it does not work or can provide any suggestions? Unfortunately I got no response from technical support. Thank you in advance. With best regards, Artur

I forgot to mention that I set all access permissions to everyone, so it is not necessary to log in to get to file browser.
