ABBA DCS historical server restart error
Thread Content
Frequently, and with increasing intensity, whenever the main history server is restarted, reading certain trends fails, resulting in no historical data available on all operator stations. Has anyone else encountered the same problem with their product? What caused it? Is there any solution?
Can Advantech servers be redundant?
Is it a problem with the trend file name? It happened here before; the file names were duplicated, and things worked properly after making the changes
It indicates an error in reading a certain file; that file must be found and deleted before restart is possible in order to restore the trends
Of course, master and slave history servers.
