    Hello,

    I am trying the new Mango (core 2.1.3 and BACnet 2.0.3) to discover some BACnet/IP points. I use the MAC address as XXX.XXX.XXX.XXX:47808 and Device instance number. But always got the error: java.net.SocketException: Socket is closed. If I manually input the details of points on this BACnet/IP network, it works fine. But I just could not make the discover working. Could you please help me with this problem? Please let me know if you may need more information about our scenario. Thank you!

    Hello,

    We want to use the iOS and Android version of DGLux to access a public view. It asks for the server, user and password. Could you please let me know what I should input to access the public view? Is it possible to have an IP in the browser and automatically open the DGLux app when user click? Thank you very much!

    Hello,

    I am using a real-time table to show some data points. I want to show all texts in the center/middle of the cell. There is such an option in the Data Grid Header and works for all headers. But I could not find the option for the contents. Could you please help me with this question? Thank you very much!

    Hello,

    We had this problem from the beginning but it just recently becomes a concern. When we open the File Manager dialog from the menu or open any Open File dialog (e.g., browse for .nav or .dgml file in the Navigator builder), there is no file or any button for adding/deleting files visible. Could you please help me with this question? Thank you very much!

    Here is a screen shot. We have several .dgml files created so that at least they should be shown.

    By the way, what we are trying to do is to upload images and use them with the Media widget. We could not make the File manager work either by clicking it in the menu or click the button next to URL in the Media widget. If I put a web address in the URL file of the Media widget, it shows black so that I think I have to upload the images to the DGLux first. Thank you!

    We have some static data points that are saved using Virtual data source in Mango. There is a start value for them and they are set as No change. When I tried to use them in DGLux, it always shows as 0 no matter which control I use (indicator, column or line chart). Could you please let me know whether there is something I did wrong? Thank you very much!

    Hello,

    We are using the new version of Mango Automation and have a question related to the BACnet module. When we tried to do the Remote Device Object List discovery, we have to turn off all the existing BACnet data source. Otherwise, there is an error "Address already in use: Cannot bind." Today when I tried to turn on an existing BACnet data source (there are three others turned on already), it also gave me this error "Initialization error: Address already in use: Cannot bind." I am wondering whether it's because there is something we did wrong? Can we configure multiple BACnet data sources to work at the same time? Thank you very much!

    Best wishes,

    We are using the latest version of DGLux with Mango M2M2. When I tried to drag a data point from the Metrics panel to a line chart or an area chart, the values all shown as 0. However, I can see the real-time value in the Metrics panel. If I drag the data point to a text indicator, it also shows the correct value. Could you please let me know how to address this problem? Thank you!

    Hello,

    I am facing a strange question. I am trying to use the BACnet4J to access a device with a list of objects such as Analog Input and output. I am able to receive the I-AM message from the device so that I can create RemoteDevice for it. However, I can't access its properties and objects and always get the error message in Wireshark: "Reject-Message-To-Network: Reject reason: 1(The router is not directly connected to DNET and ...)". I can do it using BACnet Stack.

    My IP is A.B.73.178. I compared the messages in Wireshark and found that using BACnet Stack, I will firstly receive an I-AM message from a router (A.B.73.240) which is inside my subnet. In this message, the "BACnet Virtual Link Control" part shows that the IP of the actual device I am asking for is "C.D.100.42". If I use BACnet Stack, it will directly send a "read property" message to this IP address and receive the result from it. However, if I use BACnet4J, the program will send a message to my router "A.B.73.240" and then my router will send back that error message I mentioned in the previous paragraph. Is there anything I did wrong which results in this problem? Thank you very much!

    Hello,

    I am wondering whether there is any way that I can simulate BACnet objects in VTS and access them using BACnet4J (VTS and BACnet4J are on the same computer) without Internet connection? Thank you very much!

    Hello,

    I have a question about how to get all objects in the remote device? I used the WHOIS message to get the remote device but the objects attribute is always empty. I am able to read the present value of the objects (analog input) on that remote device. Could you please let me know is there anyway I can do to get the list of objects in the remote device? Thank you very much!

    Hello,

    I tried to use the BACnet4J to access a system which uses both BACnet IP. However, there are some devices installed under Arcnet, which I think is a subnet of the BACnet IP network. I am able to access the device which has IP. However, for the Arcnet devices, I only have the device instance and a number (like 101) as the address. I am able to use BACnet Stack to access them directly using the device instance. However, I am not able to access use BACnet4J.

    Another thing I found is that in the building automation system, the IP address for all the Arcnet device is the same as the IP address of the BACnet IP device. But if I use the CAS BACnet Explorer, I found a different IP address for the arcnet device. But even with this IP I can't access the device. Could you please help me with this problem? Thank you very much!

    Hello,

    I am reading the test examples in BACnet4J and have some questions. Could you please help me with them? Thank you very much!

    1. Does the IP address for LocalDevice has to be the IP of the computer? What does this address mean?

    2. When creating the RemoteDevice, I found that the InstanceNumber does not impact the program. As long as the Address is correct, the program will always run. And most of the examples does not give any value to Network. What does InstanceNumber and Network for?

    Thank you very much!

    Hi Ray,

    I have met a similar problem as we are using a BAS that have ARCNET as the subnet for all devices and then have a BACnet/IP router to talk other IP network. In an older version of Mango (core 2.0.5 and BACnet 1.4.0), we were able to get the BACnet points by specifying the Point details as this:

    IP: The IP address of the BACnet/IP router registered on the IP network.
    Object instance number: The instance ID of the object (one BACnet point) that you want to communicate with.
    Object type: The object type of the object (one BACnet point) that you want to communicate with.
    Instance number: The instance ID of the device that directly connects to the points that you want to communicate with.
    Network number: The network number of the subnet that is directly connect to the device. Typically an integer.
    Network address: The network address of the device in the subnet. Typically an integer.

    Giving all these information, we were able to pick up the points on the ARCNET subnet.

    Recently we tried a newer version of Mango (core 2.1.2 and BACnet 2.0.3). The terminology of the point configuration has been changed. Now this way still works for us:

    Network number: Same as before.
    MAC: In our case, it is the Network address number.
    Link service IP: Same as the IP as before. But need to add the port number now (e.g., 100.10.10.100:47808)
    Device instance number: Same as the Instance number.
    Object instance number, object type: Same as before.

    Hope this could help you set it up. Thanks!
