Mango M2M Community

You won't lose your data. I used Modbus4J as the slave for testing. If you want advanced support with this issue, please use the Contact Us form.

Yes, make sure the permissions are set such that the account under which Tomcat runs can write into those directories.

A new version of Mango has been released: 1.10.0. Great new functionality is available. See the release notes page for more information.

Special note: for all users who have been patiently waiting, an OPC DA data source will be available in the next release.

Are you sure that Energia_TOT_1 should have an offset of 3? Seems to break the pattern.

Also, note that many of the points are using interval logging (not that this is a problem, just a difference from other points).

I imported your config and set up a Modbus test slave, but i never see zero values being reported. Are you sure these values are not actually being returned from your equipment? To be certain, make sure your points are logging either "all" or "on change", and then inspect the point's history and compare with the meta points.

All correct. The feed ids appear to be sequential, so they will eventually become 5 digit numbers, yes. And data stream ids are automatically generated starting from 0, but i believe they can be overridden with custom labels.

No, but just use the import/export feature. It will save you a ton of work. Change the slave id and the xid of each exported point and re-import.

I believe this problem:

20:21:50: com.serotonin.web.i18n.LocalizableMessage@a4ee1cd3

... has already been fixed, but i'm not sure in which version.

In addition, often when regular snapshot is off, the publisher send two http request, ...

This is because you are using context update with no delay in your meta point. Context update means that any update in any of the points will cause the script to run and a subsequent update on the meta point. If your points all update within a second, you should use an update delay of perhaps 1 second so that only a single update occurs on the meta point that consolidates all updates in the source points.

I don't know why you are seeing zero values without knowing more about your source points.

Oh, BTW, in that export, all of the "dp40012" points are coded as Coils, but - considering the "40012" and the fact that the bit number is set - it looks like you meant them to be holding registers.

Works fine for me, but i'm using a different slave. If you want more personalized help on this - in particular getting things working with your device(s) - use the contact us page to request support services. Turnaround is much faster, and we'll get to the bottom of the issue.

You can use a server-side script instead, and then do something like this:

Code:

return '<span style="font-size:20px;">'+ value +'</span>';

Hmm... After looking at the code, i can't see how that condition would happen. First, what version of Mango are you using? Second, can you forward an export of your data source config?

Hi Steve,

I'm glad it's worked out. Note that your equipment is returning misleading error responses. If choosing contiguous batches fixes the problem, it means that the problem was "illegal register address", not "illegal function".

I think this has been explained elsewhere, but the problem is thus... Say you want the values in registers 10 and 12, but you don't care about 11. It can be faster to do a single request for 10-12 than two requests each for 10 and 12. But some equipment will complain if it doesn't store anything at register 11. In these cases you can force two requests by clicking to only batch requests over contiguous register ids.

Hi Jérémie,

Not sure where you get that date. According to the BACnet website that addendum (135 2008j) was not approved until June 20, 2009. In any case, this could certainly be added to BACnet4J, and likely will at some point. If you have a specific need for this in the short term, Serotonin can provide a quote for building it to your schedule.

If this is a I/P data source, any chance you could expose it temporarily to internet access so that i can try it myself?
