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.

check out the modbus data source in the old mango source code for an example on how to use the modbus4j library

As phildunlap found it looks like a problem with the USB serial port and linux or rpi hardware and not a mango problem. Try a powered USB hub?
