Well, not exactly what I was looking.

How are the components created in the graphical view?

Also, are there any process control graphical widgets already built, rather than trying to spend a lot of time building these items?

Hi,

Is there a way to add custom active widgets to the Graphical view similar to the thermometer and dial? I'd like to add an animated valve or other process widgets.

Thanks!

That worked, had to restart Mango... Thanks!

The url is localhost/:8080/dashboards/

Console says Error 404 - not found

Core 2.7.12 build 481

Thanks

Hi, I am running some simple tests using Mango running on the RPi.
When I click on the Dashboard icon in order to display the Dashboard UI, I just get a blank screen.

I also have Mango running on my W10 PC and when I click the Dashboard icon I do get the Dashboard UI after a few seconds.

Is there something missing, or does the Dashboard not work on the RPi?

Thanks...

OK, cool, I will try that as well...Thanks!

I see, working now....Thanks!

I have a Data point from a MODBUS device that I read on a periodic basis.
The raw data from the device must be run through a calculation in order to display in the graphical view widget.

I was trying the Metadata data point and was not able to get it to work.
my calculation is simple in javascript:
var my = (p1-640)/16.0;
return my;

does not seem to work, meaning the graphical widget does not update.

What am I missing, is there an example similar to this?

Well, I did use that software last year on something else, so my 30 day trial has expired as I wanted to use it for exactly this issue...

Thanks...

I did try flipping the RX/TX lines on the 485, did not make a difference.

Let me ask, what USB to 485 converter have you guys used with success to talk with MODBUS devices with your software running either on a PC or RPi?

Thanks...

Hi, thanks for the reply...

All devices are RTU.
I did try changing the override timing to zero, but still no response.

I have not used this specific converter with another program.

I did install Mango on a RPi3 using the same USB->RS485 converter and I get the same results aw well.

At this point maybe it is a timing issue or maybe the way 485 works. I have another MODBUS device which does not use 485, but USB to serial and it works on the PC and on the RPi with the Mango software. So in this case the 485 was out of the loop.

Any suggestions?

Hello,

I am running Mango on my laptop PC running Windows 10.
I have a Sparkfun USB to RS-485 Converter https://www.sparkfun.com/products/9822
When I connect a MODBUS device, Thermostat the Mango software does not recognize the device. I have the Salve address and baud rate set correctly, but when I use the "Modbus Read Data" screen and click on the "Read Data" button I always get "No Response from slave 2"

I also tried 2 other MODBUS devices, another different thermostat and a refrigeration controller and I get exactly the same result.

I also notice that I can see the TX LED blinking on the USB->RS485 converter, but I never see the RX LED illuminate.

Any suggestions as to why the Mango software cannot read the slaves devices?
