AC500 webvisu - slow reaction
I'd like to ask if somebody knows what can be the problem if web-visualization from Web browser is sometimes very slow. I have no problems for at least 2 months and then suddenly the reaction time increases to at least 2 minutes (for example when I press the key to start some device) or sometimes it stops working. I need to reboot PLC to get it back to normal behaviour but sometimes I need to reboot it 2 or more times. The reaction time from "Visualizations tab" of Codesys directly from another PC connected to PLC is working well. Could it be caused by wrong CPU (webserver)? Or what could be the reason?
what do you have changed in your configuration PLC/PC in the last period?
A possible cause could be one Java updated in your PC.
The latest version of Java ( Version 8 Update 66) It can not be used without one update in PLC

Hope this help you
