Hi Rob,

I think you need http receiver since your device is going to POST data to in JSON format mango. It has nothing to do with modbus except in your device you are populating the JSON data with fields from the devices modbus map.

Hi Jared,

thanks for digging up the relevant source.

Can lines 54,55,56 in UnitUtil.java be deleted:

    addAlias(SI.VOLT.times(SI.AMPERE), "VAR");
    addAlias(SI.KILO(SI.VOLT).times(SI.AMPERE), "kVAR");
    addAlias(SI.MEGA(SI.VOLT).times(SI.AMPERE), "MVAR");

These would appear to be the culprits for displaying the units on my VAR tags as V·A.

VARh, kVARh, MVARh, VAh, kVAh, and MVAh are also units that are used for the integral of reactive power over an hour (VARh) and the integral of apparent power over an hour (VAh).

electrical power engineer here;
Apparent Power is a complex number, it has real and imaginary parts. The symbol for Apparent Power is S. The units for Apparent Power is VA.
S=V*I, where V and I are complex numbers which have real and imaginary components.

The symbol for reactive power is Q. the units for reactive power is VAR.
Q=IV sin theta, where theta is the angle between the vectors for I and V.

The symbol for real power is P. the units for real power is Watts (W).
P=IV cos theta

Nobody should be OK using VA and VAR interchangeably, they are not the same thing. only the same thing in one specific case where theta = 90 degrees are S and Q equal.

I have also had issues with mango changing the units on me when dealing with real, reactive, and apparent power, which is often the case in any electrical power application.

how many points and datasources at what poll rates and logging are you running on what hardware?

We had one mangoES die after about ~2 years of service with less than 100 points logging once per second, but up until then it seemed to do OK.

curious for 7800 points how often are they read from the datasources, how often are they logged to disk, and how much RAM are you allowing for the JVM on the 6 core CPU?

maybe a limit could be implemented so if "select all" was clicked it would only select up to 30.

Hi Phil, no failed network requests and no errors in the firebug console, it is on version 3.6.4. Guess it is a web browser thing

Hi,

When I try to save a plot from a watchlist the jpg,png,pdf exports are all blank white space. The PDF has an URL at the top. The xlsx export does provide data, and there is data in the plot.

looks like this exception in the log occurs:

actually that exception might be related to viewing the log, not the empty plots

No points have been disabled, no event messages about disabled points, just some meta points not starting back up properly after a dirty shutdown.

The meta point has a cron of 2 minutes as the update event, the script is "return p.previous(MINUTE,2).average", and is set to average interval logging every 2 minutes.

The excel report is using rollups.

Let me know if there is any other information I can provide before I start changing things that will make any further troubleshooting of the root cause impossible.

Thanks for the details on the corruption scan. Maybe not related at all!

Part of the problem appears to be that we have used meta points for one reason or another I don't understand. The modbus data point looks fine - all the data is there except for the 3 hour period when the machine was powered off.

in the watchlist some of the meta points are flatlined and did not update since the machine was powered off. here is a screenshot showing orange penstock flow and yellow PHDS gauge flow (meta points) flatlined starting at 3:25 when the machine was powered off and did not recover until mango was restarted again, whereas others carried on just fine september 26 onwards:

however on the modbus data source it is all there:

The excel report that uses the metadata points oddly doesn't show any flatline except for where there is actually missing data, so that doesn't make any sense to me how it is getting the right data from the meta point when the flatlines are shown in the watchlist for the meta point for the same time period:

and lastly the e-mail report (not excel), also using the meta data point, is not able to produce a plot with a flatline even:

Probably re-generating the point history for the meta points will fix all this. Since I don't understand why we are using meta points at all we can probably just delete them and use the modbus points and stop having these issues, otherwise I will probably have to re-generate meta point history after the next dirty shutdown.

Before I re-generate meta history or get rid of the meta points altogether let me know if you'd like to take a closer look at the data and configuration that is there in case anything looks like an issue with mango that you would like to fix.

Thanks for your help and continued work on mango
Craig

plug was pulled on the computer. upon plugging back in some pointvalues are plotting flatlines. using tsdb.

in env.properties db.nosql.runCorruptionOnStartupIfDirty=false

so no corruption scan happened when mango restarted. changing that property to true and restarting mango does not go back and fix corruption because it was shut down cleanly. kill -9 of mango and then restarting does initiate the corruption scan, but I still have flatlines in the logs for the time between computer being plugged back in and me cleanly restarting mango.

Is there a way to force mango to go back and run a corruption scan on the whole tsdb database so the data from the time period between (plug pulled) and (mango cleanly restarted) can be plotted, or is that data not even recorded since part of the database for those point values was corrupted?

is there any reason runcorruptiononstartupifdirty is set to false by default?
is there any way I can detect when data is not being logged due to corrupted database?

Thanks.

I am trying to use units MVAR and MVARh but mango keeps changing them to MV*A and MVAh.

Can MVAR and MVARh be added to the list of units?

Hi Phil,

This was on mango 3 at all times. I had upgraded to the latest mango 3 a week ago after the problem happened the first time.

I have just upgraded the mangoNoSQL module. No update to the excel reports appeared in the list of newly released modules.

We will make sure to upgrade all of the MangoES with version 2.8 to the latest 2.8 as well.

Thanks for such a quick turn around!

Hi Phil,

Thanks for getting in touch. I can report back to our customer that you are working on it.

We made it a couple days before running in to this issue again. The first exception is in the excel report purge, then after it looks like the corruption scanner has an exception and then no more reports run after that, and then the queue fills up.

I had the same problem not being able to shut mango down cleanly after the exceptions have occurred.

I did change the runCorruptionOnStartupIfDirty to true after I the first bout of corruption occurred.

Exception in the excel report purge:

It seems for some reason there is some corruption in the Mango NO SQL database as there are some log entries regarding repairing the corruption, but from that time on none of the scheduled reports (hourly) complete successfully so the queue fills up.

What showed up in the console though that isn't in the log is this NullPointerException, but it appears to happen before the database corruption:

Here is the contents of the corruption scan reports:

Now in the excel reports tab there are a bunch of reports running and a bunch queued.

The forum won't let me upload the ma.log or threads.json, so they are here

any fanless hardware on the horizon?

if you want to work strictly in mango you could read the 4 byte value as an unsigned long integer and then use a meta point to mask off each byte and try reassembling different arrangements of bytes and converting types to float until you find the float that has the correct value.

Here is an excerpt from another scada system's help file:
Control byte order for floating point values (the Modbus driver supports floating point values).
Some systems expect to use a different byte order for their floating point data.
Allowable Values: 0 to 3, where:
0 - Byte order = 1 0 3 2
1 - Byte order = 3 2 1 0
2 - Byte order = 0 1 2 3
3 - Byte order = 2 3 0 1
Default Value: 0

mango supports option 0 and 1 I think, so it is also possible that the system you have is using option 2 or 3 if you are sure you aren't off by one and neither 4 byte float and 4 byte float swapped worked.

a byte is 8 bits. so the flow rate is a 4 byte float and the total is an 8 byte float. There are two settings in mango for each of these, 4 byte float and 4 byte float swapped, and 8 byte float and 8 byte float swapped. Try both, see which if any works.

make sure you are not off-by-one with the register addresses. find a simple register that is INT type and make sure you can read it correctly and that you are not getting the register before or after.

If neither work then I would use the program called qmodmaster to connect to the salve and see what the exact bytes are at what address and then you can try different arrangements of bytes to floating point until you find the one that works.
