Interesting. Reloading the entire web server just to start new log…
Does the new approach stop reloading?Hi,
You need to specify a pulse length and polling rate. And make sure that polling rate is fast enough to detect a pulse.Hi,
Currently the MQTT driver doesn’t support string values. To support strings, update is required.
Also Rapid SCADA version 5 has a limitation of max. 8 Latin characters in tag. Is 8 characters enough for you?
What kind of string values do you need to read?
What’s the proper way to have a client showing the scada page 7×24?
It depends more on web server. For example, by default Windows IIS restarts application pool every certain period. It’s possible to disable restarting.
I haven’t heart that Apache also restarts something. Anyway, after web app restart, you will see break lines (——–) in ScadaWeb.log and then
2021-02-21 00:00:42 <opticalsensing><www-data><ACT> Initialize common web application data
How regular such text is in the log?I disabled chart plotting and hide minute data export. So there should be one or more cause other than these 2.
Good idea.
I am going to make a program to monitor the cpu usage by mono, try if I can capture what cause the issue.
Probably there should be utilities to read CPU load, provide by SNMP and read by Rapid SCADA.
His email is below this article.
i have write some kpdrivers moddrivers. how can i put it on website and sell it?
Are they ready for other users? I mean tested and contain manual?
Could you provide description of the modules?
It’s possible to publish them to the repository after some validating. Please create new topics to discuss the modules. It’s better, a topic for each module.Note: Mono may work incorrectly if you open the web app by local browser and also open it remotely by IP address. It’s better to use Linux without GIU.
I faced that Mono hangs after heavy operation like opening a chart for a long period.
We will get rid of Mono and move to .NET5.Can you reproduce CPU load?
Will it effect scada if I kill the www-data PID?
Server and Communicator continue work. So you can try killing the process.
First, try restarting Apache by restart_apache.shError getting events by the filter where channels= , view id=1:
Scada.ScadaException: User not logged on.JavaScript on a client page requests for data, but user is logged out. This is not a cause likely.
Usually when user is logged out, he is redirected to Login.aspx automatically. For some reason he was not redirected. To stop this error, a user should close a webpage or navigate to another page.
May be there should be a tool to export a project to RDBMS. This would be very useful for complex systems and different integrations.
