Hello jkyner,

Can you be more specific on the following post you made, please?
I've been trying to put my power meter (connected to Mango via Modbus serial) on our LAN using Moxa 5230 without much success.

What data source should I use to configure/connect to the Moxa 5230?
And what "operation mode" should I choose for Moxa 5230 for Mango to connect?

TIA,

joohwan

I should have said Mango works fine with a Lantronix Intellibox Modbus Gateway with RTU slaves but also works fine with the Moxa 5130 (a basic Ethernet/RS485 SDA that is not Modbus-aware) for those Modbus slaves that can handle the 6-byte Modbus TCP-RTU header forwarded over RS485.

.. you able to create own JAVA classes.. ? Well I'm am not sure. My programming skills are limited and I have never worked with Java. But if I could find out the basics in how to locate, clone and modify one of the existing classes I might be able to hack the driver to talk this protocol.

Closest you are going to get to that is a small controller or thermostat. Maybe check out Viconics, Exactlogic or BBP Energie in Canada.

All of those are MSTP and you will need a router. Loytec makes a touch panel with a temp sensor and this can be on IP but probably this is overkill.

@zumiani said:

You should look at the PLC program.
Maybe a task turn it off after a while..
Surely it isn't due to Mango or Modbus!

Ok finally found the issue! I had created a binary 0 reset on the program I had wrote and was talking to mango at the same time. So everytime I had set a point in mango my program was reseting that point after 2 seconds.

So now that I finally have it all working I am running a BAC-HD150 bacnet controller for the Mitsubishi City Line system with Bacnet IP of course. And running custom valve and boiler control for large steam system. I am controlling that with Wago 750-841 Modbus Field Coupler. I will update you with my setup once all is done.

Thanks and hope this helps others.

might be best to start a new topic in the "user help",

Love this part:

In a moment of rare SCADA-software sanity, the offset is zero-based.

You will first need to define a Modbus data source and add your two points to it. Then take a look at the Meta Data Source. You can use the two modbus data points as input to a meta data point that combines them using javascript.

Hello! I've got a problem, that I've described in modbus4j help forum. Here is the link: https://sourceforge.net/projects/modbus4j/forums/forum/810600/topic/3841078/index/page/1
Have anybody had such an experience?

There is a serial port (RS232) and also modbus serial is supported, you can start from the examples.

Dear all,

does anybody know which GSM/GPRS hardware device interfaces with Mango through GSM/GPRS? Ideally that piece of hardware would have a data logger and be battery-driven. It would log the sensors signals 0-20mA, 4-20mA and/or binary input.

Any hints? Ideas? Experiences?

Best wishes

Sebastian

May be a better way of doing this is to

1 - write a JSP page to run an op system command
2 - use the JSP to loop through the reply to create a neat page with the collected data
3 - use an HTTP retreiver to pick up the data (same way as I am doing for op sys stats)

This means thoe whole process is under mango control and mango timings

But I like the idea of using OWFS if a device is not mango supported

Hi Francis - while on the list, we are currently giving priority to items that are included as part of project development work we are doing for Mango customers.

While we do see a lot of value in this, we may not get around to it ourselves until this development can be co-funded through a project or a contribution from a user.

I don't know what to say. I've tried the 1.8.1 download on Windows and Mac using the available download and install instructions, and accessing a Modbus TCP slave, and it works perfectly. If this continues to be a problem for you i can only suggest you wait for the 1.8.2 release, forthcoming once some details with a collaborator are worked out, hopefully in a matter of weeks.

Maybe this month. Depends on multiple factors.

Just a note that the DS2423 functionality will be available because Antsu provided the hardware for testing. So, many thanks to Antsu.

Hi,

I have Mango running with wireless sensor nodes from Jee Labs. The JeeLabs hardware and software are based on Arduino and is open source hardware/software. You can get JeeNodes from jeelabs.org either fully assembled or as a kit (note: I'm not affiliated in any way with Jee Labs).

To get JeeNode rooms data (temp, presence, humidity, etc.) into Mango, I made a rooms2modbus sketch (in the Arduino world, that's a program that can be compiled and loaded on you microcontroller). This makes the central JeeNode/JeeLink act as a modbus RTU slave. For those interested, you can get the source here:

Hi

From experience the best connector is the link45 as it can manage difficult cable configurations (See http://www.maxim-ic.com/app-notes/index.mvp/id/148).

I started with a USB one and it constantly gave trouble. I have found one wire networks to be a law unto themselves, working fine for a week then losing sensors for days without a change being made.

I wanted to try to use the DS2450 A/D converter to interface with Mango to monitor field signals from HVAC equipment. I have only several temp sensors on my one wire so far. I use the standard serial adapter to my Win XP PC as the bus host.

I built a circuit to interface with and isolate from the field voltage which uses an LTV-814 (one channel) up to LTV-844 (four channel) AC/DC input opto-isolator. The output transistor of the LTV chip drives the input of the DS2450. I am using 5VDC (currently USB powered) to drive the output side of the LTV chip.

Initially it did not work. However after plowing through the DS2450 datasheet, I learned the default setting for the DS2450 for input voltage is 2.55 volts maximum on the inputs. Since I was using 5V it did not know what to do and returned a big fat 0.0 to Mango (and One Wire Viewer). I then used a voltage divider network to bring the input down to a level that the chip would recognize and report in it's default state.

An optional input value is 5.10V, but there is currently no way in Mango to select the input voltage or the resolution (default 8 bits) of the DS2450.

The default settings for memory map page 1, Control/Status starting at 08h is:
(hex) 08 8C 08 8C 08 8C 08 8C

If it could be modified to:
(hex) 08 8D 08 8D 08 8D 08 8D this would give 5.10V input enabled

The settings are all volatile and revert to default when the chip is repowered so they need to come from the host software every time the one wire bus is powered or reset. I'm not a programmer so I leave that to Matthew as a possible improvement !

Hope this helps someone.....at least I got to relearn hex to figure this out. Short lesson is if you are over the input voltage you will get 0.0 output. Also, when you really are at zero input voltage the chip output floats at 0.03 or so on all channels. I have two DS2450 and they both do the same thing.

Next job is to get it off my desk and into the field.

Hi,

I just discovered Mango M2M. I am so pleased that someone has taken the step to allow the little guy onto the feild.

I downloaded and installed and WOW discovered the device instantly and connected. Worked great out of the box. :D
I have some more learning to do, but I wanted to say thank You Very Much. I will be testing and playing for days to come. :lol:

I can see a very bright future for this product.

Thanks again..

Hi

I've just found your question. I've got about 30 temp sensors and some switches set up on a 1 wire network. I'm planning to control my complex heating system through it using Mango.

Getting it to be reliable is a right pain. Its very sensitive length and hoe the sensors are added. This article is very helpful
http://www.maxim-ic.com/appnotes.cfm/an_pk/148

If you want to do some testing to check the system is working either use the dallas software or LOGTEMP by mr soft both free

Here's my public view page http://www.bacwak.net:8080/public_view.htm?viewId=8

Which is a bit scrrewed at the moment as i have been playing with dials and buttons on it

Cheers

Keith

Keith,

What switches are you using and how do you have them connected? Powered, parasite, pullup resistors, etc? The reason I ask is that I have switch module D2P from EDS (DS2406 based). Mango sees the switch (but only one, it should see A and B since it is a double I/O) but it does not sense the switch staus (binary change). I am using this on serial input and parasite mode. Interestingly enough I have the same exact problem with LogTemp. However, Dallas/Maxim viewer sees status changes perfectly.

Anybody else, feel free to chime in.

BTW, love the Mango software so far.

Mike

Nice catch. This was a bug in Modbus4J in the WriteMaskRegister failover. I've checked the fix into the CVS repo.
