Can someone explain this more? Looked at manual and still unclear. We have some stations that seem to be inserting some random values at times that may be coming from a cache. Wondering if this may fix it.
We cache data from the historian in the runtime. So if you have an easy chart polling and the cache turned on we will only poll for the new data since we already have the older data. You get better performance since we don’t have to query for the data all the time.
Now there was a problem with the cache prior to Ignition 7.5.6 so turning it off in your case may fix the issue. I would recommend upgrading if you can.
Ok,
We are on 7.5.5 so will look into updating.
Thanks
