What's the meaning of 'send regular snapshot' in a HTTP publisher? If it's disable, what's the impact on publishing the data? Thanks. Attachment: download link

Hi All, I'm looking for some help using Mango with my Leonardo Arduino. I've looked through the various posts on this site on the subject but so far I've been unable to find a definative Modbus library and some sample code that will work for testing. I've downloaded the latest modbus_rtu_slave.pde and ModbusSlave.tar.gz from JPMzometa's website but have been unable to get the sketch to compile and work with the library. I've also tried following a post off here that had some sample code and links to the latest library but that also failed to compile. Can anyone please point me at the definative Modbus library version and a compatible sample sketch that I can use to engineer my project? I'm programming with Arduino version 1.0.5-r2. I'm fairly new to Arduino, I'm just getting into it as a hobby but I'm an industrial automation engineer so I'm familiar with automation, PLC, SCADA concepts. Any help or pointers would be truly appreciated. Many thanks, Lee :)

I can't wait Joel :D ! @JoelHaggar said: Something to know is that in a very near release of the Mango Automation Enterprise license we will offer a NoSQL database option that gives impressive performance for very large systems.

Hi Joel. I make the question clear in attached pictures. please notice the red rectangular area in the two pictures, there is no save button in opc point details page. without that button, the point properties cannot be saved after modification. Attachment: download link

OK now, it seems solved after convert to mysql database.

I checked mysql database, all the tables were created, but not all of the datas converted into mysql.

Thanks very much for sharing, I'm sure that will be useful to others. Joel.

I did the following step if I remember correctly. Add one data point (offset=0) for Modbus IP publisher. I works. Add two more data points. Only offset=0 is working. The other data points are 0. Remove all data points, except offset=4 and set to offset 0. It works again. Add back the previous data point which was offset=0 to offset=4. It works. Do something like steps 4 for others to make it work. It seems to me that the data points has to set to offset=0 and then change to other offset value to make it work. But I am not very sure.

ray, Thanks for pointing this bug out. I have created an issue for it in our Code repository: http://github.com/infiniteautomation/ma-core-public/issues/147 It will be fixed in the next release.

Hey, I want to run Mango on Kubuntu 13.10. I installed/moved to described points following files/applications: librxtxSerial.so: save in <jdk1.6-home>/jre/lib/i386 RXTXcomm.jar: save in <jdk1.6-home>\jre\lib\ext apache-tomcat-6.0.20.tar.gz mango-1.12.5.tar.gz

Well, I have a feeling there could be a better solution, but you might be able to solve this using a point link. The idea would be Select from your database into the value point. Create a second SQL point that sets a timestamp value to some useful place in your database. Create a point link from the value point to the timestamp point, and use the pointlink to turn it into something like ('src Pnt Name', timestamp) to set that value into the database (via the second SQL point). Build you select to reference that stored timestamp so that you get the right point. It's not the most elegant solution, but it should ensure that you're getting new-er values while still ensuring you're not just getting the new-est.

Yes - this should help. Will let you know. Thanks!

I tried it on both ver. 2.2 and 2.06. It came with the same result.

Hi Joel, The session time out is set to 2880. I have tried setting up a timer triggering a browser reset but this doesn't help. Only the mobile app is affected. Cheers, Matt.

Thanks for your help Joel. Seems to work a treat. It would be nice if all this could be integrated into the data point down the track though. It would make scalability much less if an issue as for each data source you wouldn't need 2 extra points per event. Cheers, Matt.

This is for sure possible but your question is very general. We would need to have details about how we need to interface with the files and what Mango needs to do. I would assume there would be some documentation you can provide? Joel.

Thank you for the workaround and I think it will be a good temporary solution. Please consider a permanent fix in the next coming release. BR, Ricardo

ok. thankyou

Hi all, I am using Mango to get MODBUS data from various sources, including RTU's residing on Xbee nodes via a Digi Connectport X4. I would like to POST data to the Etherios cloud using the Mango HTTP sender publisher, and have successfully tested this using HTTP POST with a Python Script. However, I am unsure as to the format of the Static Parameters in the Mango HTTP sender properties. The path is http://<hostname>/ws/DataPoint/one I need to add the following snippet of the HTTP POST method to a KEY: <DataPoint> <staticId>one</staticId> <data>42</data> </DataPoint> I cannot use just the two entries: KEY=data and Value=42 KEY=staticId and Value=one Somewhere I need to add the "DataPoint" header Obviously the value "42" would be where I put the Mango point "Parameter name", but I am first trying to send just a static value. The "staticId" is the Etherios Data stream ID, and remains constant. Can anyone shed some light on this?

Sending the data (what I'm thinking of as the request) is not the issue. You could send any data by using the Point Identifier in the data point details as the Device ID # and setting values to that point. Unless the data returning from the device also is fixed (which would probably make it uninteresting) the checksum will not be fixed and we'll still have a problem of telling one message from the next, or knowing if we've finished reading a message.
