I can’t find any documentation about this for scada administrator so… questions! Channel columns meaning and use:
– WRITE EVENTS: means write to the events data file? if not… they are shown today but not saved? Not sure what it is for.
– EVENT SOUND: will it play some sound on server? on clients table view? on a scheme?
– EVENT ON CHANGE: on change depending on limits? (which limits are aplicable?) any change respecting last data?
– EVENT ON UNDEFINED: when is it undefined? no comm data received? after some time? (I think I remember a relationed parameter but don’t remember where is it)
– LOWER/UPPER LIMIT: what’s the utility of those limits?
– LOWER/UPPER ALARM: Event generates if below/above this limits?
Object and device fields… are needed for something?
Thanks and happy weekend!May 20, 2016 at 4:01 pm #1215
Are any events shown when in Report/List Chart view?May 20, 2016 at 6:28 pm #1217
WRITE EVENTS: if false, no event for the channel will be written and shown.
EVENT SOUND: plays beep in browser. Just try.
EVENT ON CHANGE: on any change. Usually the option is used for discrete values.
EVENT ON UNDEFINED: e.g. connection is lost. Event fires when the channel status is 0.
LIMIT: I recommend trying it using SCADA-Server generator.
Object field is optional. Device field is required if channel value is measured by a device.
Are any events shown when in Report/List Chart view?
Sorry, I didn’t catch the meaning.
Have a nice weekend too 🙂May 23, 2016 at 3:24 pm #1225
WRITE EVENTS… is like “Events enabled” ? I think ‘events enabled’ is more understandable.
AVERAGING: how does averaging work? continuos average? last 100 values average? last minute average?
By the way… as only minute-data is shown… what happens when communicator sends several values on the same minute? does an average? maximum? latest?
Limits… I will try to guess it but that’s not an answer.

When in a report view with some list chart graphs there are no Events shown. Useless? => hide it, makes you think there are no events.May 24, 2016 at 1:11 pm #1242
I agree, “events enabled” is better.
Received values are summarized within a period (minute or hour) then divided by their count and the result is stored to archive.
In the new web app the chart list will use the common page template, so events will be visible. Thanks, recently I thought whether it is required or not.June 7, 2016 at 2:09 pm #1269
Just one doubt more…
As nothing is 100% reliable and this test-wireless link even less… I get some events displayed as: Normal after a loss of link (maybe 3 times a day, but with 100 channels…)
Is there any option to avoid/ignore NORMAL events caused by a communication error?

Uncheck Event on undefined checkbox for these channels.June 7, 2016 at 3:33 pm #1271
Hehehehe… I already understood that column…
Event appears and checkbox is NOT checked!June 7, 2016 at 5:27 pm #1274
Do limits are set for those channels?June 7, 2016 at 5:33 pm #1275June 8, 2016 at 7:36 am #1279
Something wrong with the image.
It requires changes in SCADA-Server logic. The changes may be done within a common queue of tasks or may be done fast for a fee.
As a workaround, limits can be implemented using formulas, but in this case you need separate channels for alarm signalling.June 8, 2016 at 8:19 am #1280
I tried several times to link image, after 5 minutes i leaved it out, anyway you got it.
Leave the task for the queue,it’s time to make link reliable!!
