Hysteresis on Historian Archive
Hello Everyone,
I have a question!
My IEDs send to Zenon 8.00 some cyclic measurement (2s) from field and I use this data for trend graphs.
To preserve data storage and archive of server (10 years average life of the plant), I would like to save the data on archive only if they break a max-min value.
I'm not interested to collect all data sent cyclically but I want to show only main data with an approximative interpolation for trend graph and archive it on a txt file with timestamp.
I can set up the archive only with cyclic time and with a trigger variable.
How I can do it? There is no option to set a simple hysteresis? I need to use straton ?
Thanks everyone
