Using Web-visualisation (webserver.exe), does the historical trending work ?
I added a trend in a visualisation page. I set the recording to 'history' and I set a path and a filename to keep the actual trending files.
When I log on using Codesys programming tool, I can see my history file been created and stored on the C: drive.
But when I use the Web Server (webserver.exe) and a Web browser (firefox with java) I see the actual trends but as if it was set to 'only on-line' -- No historical file is created on the C: drive !
Did I miss a setting somewhere ?

I have it running last night and i see the same problem.
however it looks like it is running in real time it does not.
what is exact problem i do not know for now.
I have a wago 841 running webvis and same firefox etc.
switch off the best fit in online mode.
and the old data is not transfered to the web so if you start your web it wil start the trend. however when in background it will keep receiving.
for a complete picture you will have to receive all data.
The trend graph display correctly in Codesys (Visu) but is blank when using a WEB browser.
