Whether I create a new meta datapoint or edit an existing one, when I click on Generate History that icon blinks for a while, and then a pop-up window displays the number of points generated. The number of points generated seems to correspond to the "Update event" interval and the inception of the first input context point; the wait time also seems to correlate to the number of points generated. However, the "Point Details" page does not show the newly generated points: neither in the point history nor in the graph. I suspect that the point history is being generated but not stored in the database. I use this feature a lot, both when fine tuning formulas or when creating new meta datapoints. Can you please look into this ASAP? Relevant modules: core 2.0.6, meta 1.4.0 On a related note, when I was using Mango 1.12.4, it seemed that I often had to purge all data before generating history. Does "generate history" always generate from Inception to Latest, or do I have to purge old data first? What time interval does it generate over if I already have points in the history? Thanks.

I you set the update to start of day and use this it will work: return 24*(b.past(DAY).get(true).proportion);

got it to work. thanks for reply.

i mean when a event handler sends an email i want it to have custom subject and text like Subject : low voltage at battery 1 Where can i customize these email messages ? regards

Hi, I am using the following to get the temp from an NTC T = t1.past(MINUTE).average; THERMISTORNOMINAL = 10000; // temp. for nominal resistance (almost always 25 C) TEMPERATURENOMINAL = 25; // The beta coefficient of the thermistor (usually 3000-4000) BCOEFFICIENT = 3435; // the value of the 'other' resistor SERIESRESISTOR = 14910; average = 1023.00 / T - 1.00; average = SERIESRESISTOR / average; steinhart = average / THERMISTORNOMINAL; // (R/Ro) steinhart = Math.log(steinhart); // ln(R/Ro) steinhart /= BCOEFFICIENT; // 1/B * ln(R/Ro) steinhart += 1.0 / (TEMPERATURENOMINAL + 273.15); // + (1/To) steinhart = 1.0 / steinhart; // Invert steinhart -= 273.15; // convert to C return steinhart ; Trouble is that when even for the past one hour where there is **NO **t1 value received, the average function still returns the average based on whatever was stored earlier. I was expecting that in case of no data, the average function based on time would return a NULL. Any thoughts / suggestions ?

Please contact me directly to discuss. We can set up a cloud account for you.

Hi, we don't have much experience with DNP3 ourselves and the code for that module was not written by us. That said there has been interest recently by several companies, if you would like to work with us to upgrade this module please contact me privately, Joel.

I've had a similar problem. It seemed that if certain data points were enabled, everything from that device would read "Point value may not be reliable." The problem seemed to go away for the remaining data points if those "problem data points" were disabled. After some experimenting, the problem went away entirely if the following boxes were selected in the data source menu: “Use multiple write commands only” “Contiguous batches only” “Create slave monitor points”

Mango is setup with: admin admin as the default user name and password. Hope this helps Steve

Got it to work. Just needed a pc reset.

Hi, I use event process commands quite a lot, but i now have a need to pass the value of a mango variable to the batch file... Can this be done? Or would i need to trigger the batch file from a server side script? Is that allowed? Any tips on how i could do that? Thanks Skiv

Thanks. I posted another query on Modbus and having this act as a slave. If this option was available then it would be ideal. Until I have a way for a remote GPRS device to get back values from the server, I can't yet consider Mango for any commercial application but I will continue to use for home use and look out for an option in the future. I may even consider doing some coding myself. Cheers Dave...

@JoelHaggar said: I'm not aware of a terminal window you can open. You just start and stop the service by right clicking on the service. Joel. I believe now I can access this information via the logs, which serves the purpose. H

Thanks Joel. This would be a great addition to Mango as it would give an alternative option for devices that are on the internet but without a visible IP address, GPRS based devices for instance, to be able to send and retrieve parameters. I use this very method with VTS for a commercial application I have with an oil company. The binary transmission is also smaller than using HTTP. I can see some real potential uses for Mango in my commercial ventures, for some of the smaller projects were a full blown SCADA system is beyond their budget. Right now, it is purely for development and home automation.

Thanks for the reply Joel. I still can't connect on my mobile, so I asked another friend to connect from another state on 8080/safari and he had no problems. So I am going to put it down to poor internet connectivity here in Australia and/or an issue with my mobile co. One thing that concearns me with the iframes, is someone, or many people could copy the iframe address out of my website source code and paste it in another website/s. This could cause connectivity issues and misuse of data. it would be good if iframes could be more secure somehow. A workaround for me would be to add my company logo to the graphical display. Thanks Joel

Regarding your question about TCP, yes, this is possible, but currently not supported in the module.

Hi Ray, Version 2.0.1 will include a number of fixes. What kind of network is 50? Not sure about the 169.254 thing. It's certainly not in the current source pool.

Hi, I'm not an expert with this, but I wonder if this will help? http://forum.infiniteautomation.com/forum/posts/list/1402.page
