FBUS-HSE/H1 Linking Device-- unprotected surface mount boards ?

With the HSE Linking device, I noticed that the circuit board opposite the heatsink vent is exposed to the environment. 
This circuit board appears to be an uncoated surface mount (fine pitch) board.
Presumably, this would be mounted facing the "ceiling" of the industrial wiring cabinet, since you would want the processor heat to escape from the top. 
Unfortunately, this means that any dust and junk in the atmosphere collects on the surface of the SMT board.  It wouldn't take much in the
way of fine metal fragments to cause shorts.
So is the board coated ?  Is there an "approved" way of covering the vent with an air filter to protect the device ?

Our products meet pollution degree 2 requirements. Adding a filter will not lower pollution degree. You can install the FBUS one of NI's enclosures or an equivalent enclosure to reduce exposure to dust. Enclosure used should have UL or TUV certification (approval) for Ingress Protection (e.g., IP54 min).

  • What is the default IP address of the HSE/H1 Linking Device?

    I am evaluating an NI FBUS-HSE/H1 Linking Device. I am using a PC (not a DHCP server) to communicate to the FBUS-HSE/H1 but the PC cannot detect the device. When not assigned an IP address by a DHCP server, does the FBUS-HSE/H1 have a default IP address? If so, what is it? If not, is there a simple work-around?
    Chris

    Hi Chris / Sean,
    I assume that you mean you got a freebee DHCP "server" & not "client", as most PCs are clients.
    Any chance you could direct me to the "freebee" as I have tried a few free ones for this problem but
    have had no luck.
    Currently I am using an old ADSL modem that has a DHCP server, but it means another box stuck
    on the network.
    I am also hoping that NI will allow future versions of the LD to boot with a "default" address as most
    other LDs now do (something like 10.0.0.1-254 range would be nice).
    Sean - is this on the wish list for a future S/W upgrade. Just about everyone that has tried to get
    one of these LDs running has come up against this "non-standard" arrangement.

  • HSE/H1 Linking Device Not Communicating

    I have a HSE/H1 linking device. It does not communicate with the
    NI-FBUS Interface Configuration Utility, version 3.1. I reset it in accordance with the
    manual, but it still did not work. This item is less than 1 year old and,
    as such, it is covered by the warranty. Can you offer any other trouble
    shooting suggestions? If not I would like to return it for repair or
    replacement.

    I guess your problem is that you can not find any linking device when you tried to add a HSE linking device in the Interface Configuration Utility, right?
    Please make sure the LD connects a DHCP server and have a IP address, and I strongly recommend you use a 10Mbps hub(or switch) instead of 100Mbps hub.
    If it still doesn't help, please send e-mail to [email protected] for further support.

  • FBUS-HSE/H1 set fixed IP-Address

    I like to connect the FBUS-HSE/H1 to a 2nd LAN-Card in the computer (the 1st accesses the factory-wide network and should not be used). This card has no DHCP server available. It is possible to set the FBUS-HSE/H1 to a fixed IP-address in the address space of the LAN-card ??

    You can not set the FBUS-HSE/H1 with a fixed IP-Address, the linking device can only obtain the IP address via DHCP server. I suggest you try to use some DHCP software in the host side to have the IP address assigned to the linking device. We have ever used the Vicomsoft  (www.vicomsoft.com) DHCP Server software to configure with FBUS-HSE/H1 linking device successfully.
    On the other hand, since you have two LAN-cards (NICs) installed, you might need to pay attention that the current version of NI-FBUS CM or Configurator (for HSE version) can only connect to the first LAN-card; so I suggest you assign the factory-wide network to the 2nd card to avoid communication failures. Good news is that the next version (v3.2) of NI-FBUS software (CM and Configurator) will support multiple network interfaces (NICs).
    Hope it helps.

  • Using FBUS Monitor with FBUS-HSE/H1

    Hello,
    i want to use the FBUS Monitor SW with the FBUS-HSE/H1 (Ethernet) HW. But there is no interface to select. The NI FBUS Configurator works fine with the HW. I using the DHCP Server Tftpd32 v. 3.03. What can I do?
    Thank you very much!
    Harry Schäuble

    NI-FBUS Monitor should be used with NI-FBUS Interface device.
    For example, if there is a HSE/H1 linking device, you can use Monitor to obtain H1 data on this device by connecting a cable between H1 port on HSE/H1 linking device and H1 port on NI-FBUS interface card. But for HSE, NI-FBUS Monitor does not support the detection and capture of HSE data.

  • FBUS-HSE/H1No Network Status

    My HSE/H1 Linking Device was working fine but now it doesn't seem to work.  The H1 Port Status lights are off. 
    Here is a little background which may have nothing to do with the problem except they occured at the same time.  Recently I had a problem where the PC running my appilicatioin HMI using OPC and Communication Manager 3.1 locked up due to running out of virtual memory.  I suspect a memory leak in the Communicatioin Manager.  I have had this problem where the memory usage would keep creeping up the memory usage until I would get running out of virtual memory message.  If I shut down the Communicatioin Manager, the memory usage would drop significanly to the point where I first started.  If I started up the application everything would be fine for a week or so and then the same problem.  This time I was away for awhile and upon return the PC was so locked I had to pull the power plug.  Upon trying to restart the Communication Manager I would get a meesage that the port was not avaialble. 
    The H1 Port status lights were out.  I rechecked all connections.  The Monitor was showing a Probe Node going to the device which should Dead but no response from the HSE/H1 Linking device.  I did a reset the the Linking Device but this had no effect.  Is my unit really dead? 

    Hello,
    Would you please let me know the status of the other LEDs? If the Ethernet LEDs are in proper status but the H1 network status LED is off, the most probable reason is that the linking device didn't successfully get an IP address through the DHCP server. Please try to restart the linking device (power off and then power on) and force it renew the IP address.
    Hope it helps and please feel free to let me know if I could do more help for you!

  • Linking devices residents in distinct segment via HSE

    I would like to make a FBAP link between a H1 device under Linking Device and HSE device with FBUS Configurator.
    But, FBUS Configurator seems to disturb such linking.
    Now, a Linking Device and a HSE device are working on HSE.
    FBUS Configurator shows those two links, and FBAP and Schedule are shown in each links.
    Trying to drag&drop the HSE device's FunctionBlock into LinkingDevice's FBAP editor, it disturbs such behaviour.
    Can't I make such linking ?

    Thank you Chris.
    I've read the FF spec again and I've not understood deeply, but I could imagine that H1 device may not be
    transparent from HSE device.
    Because, the difference of LinkObject mechanism between H1 and HSE seems not to be able to link HSE
    and H1 device.
    Assuming it is true, nobody can understad why H1 to resident in HSE via LinkingDevice.
    Or, only the NI-FBUS Configurator is not capable for such use-case ?

  • NI FBUS - HSE/H1 Capabilities

    I am in the process of looking for alternatives to Rockwell 1757-FFLD (foundation fieldbus linking device).  We have a couple of major issues with this device that are requiring us to look for a different solution.  
    1.  Can we use the NI FBUS - HSE/H1 with ControlLogix?  How is this done?
    2.  Can the Emerson 375 Fieldbus Communicator communicate on an H1 segment at the same time the NI FBUS - HSE/H1 and does it interrupt communications to the devices on the segment?  The 1757-FFLD does not support this.
    3.  Can we add devices and configure to an existing segment with out interrupting the communications to the existing devices.  Explain how the schedule and configuration gets downloaded.  Currently with the 1757-FFLD, when we download the H1 segment we lose communications to all the devices.  As the configuration gets loaded to each device, the device returns online.  We are seeing communication interruptions of 10 minutes because it takes 10 minutes to download that segment.   We could live with a scenario where it momentarily interrupted the communications to 1 specific transmitter while it was downloading to that device.  When we try adding a device online and just download the configuration for the new device, we get a Schedule Download error.  The only way to get a clean download is to download the entire H1 segment. 
    4.  What is the recommended number of devices on a segment? 
    If you would like to discuss this via phone, I can be reached at 815-774-5278.
    Thank you for your time.
    Regards,
    David Chasse

    1. NI FUBUS - HSE/H1 LD will not work with ControlLogix
    2. If you have the latest firmware in your 1757-FFLD(C), it fully supports the 375 HHT.
    3. You can use NI FBUS Config with 1757-FFLD, however, NI FBUS  Config software does not  allow partial downloads (software imposed limitation)... full downloads stop everything on the segment.  If you are using RSFieldbus software, you can do partial downloads, add IO (FF Scheduled Communicaitons) on the fly w/o disrupting the network. 
    4. In theory you can put 31 devices per segment (w/o repeaters), however, this is not practical for various reason (voltage drop, slower updates, VCR connections, and etc.).  The biggest thing to watch is the number of VCRs (producer/consumer connections on H1 are called VCRs).  A valve could produce Postion, Torque, Alarms, DI and then consume CmdPosition... This valve would produce 6 VCRs and consume 1 VCR.  A Temperature probe might only produce one VCR.  The general rule is one or two valves and 6 to 8 other devices per segment.  If you have two valves (2 x 7 VCRs) and four mass flow meters (4 x 5 VCRs) that means you need to move at least 34 packets (one-way) across the network.  FF can only perform 50 messages per second.   The bandwith is split between scheduled and unschedule at about 50/50 ratio so you really only get 25 MGS per second scheduled so you are looking at 1.3 seconds of wire time.   Realize the device require some time to create this data (D/A) before they can publish the data to the network (not less than 50ms, some times as much as 1000ms).  So the real update time could easily be 2 seconds or more (one way across the wire).  Given this performance concern, the original FFLD firmware only supported 16 Producer and 16 Consumer connections (VCRs) per segment...  Many applications consumed many more data points than they produced (especially application that just monitor data and don't do any loops).  So new firmware opens this up to 64 Producer and 64 Consumers per segment..... with a warning that moving this much data across the H1 could be slow.

  • FBUS-HSE/H1 not detecting 100Mbps and status light blinking green

    I had the HSE/H1 connected to my network, but it decided to go crazy on me and drop off the map. I know the IP Address of the unit, but am unable to connect with it anymore. I did a factory reset on the unit, but am unsure if that resets the IP address as well. If that is the case what is the best way to force an IP address on the unit? The status light blinks green at a rather fast rate as well. I can add the ethernet interface board in the interface fonfiguration utility, but can not add the hse/h1 LD since it just sits there and listens for the board forever. I hope it is an easy fix and not a matter of the unit died on me.
    Thanks
    Kyle

    The blinking status LED indicates that the linking device is in standby state. The linking device will be assigned an IP address automatically through DHCP. 
    Please check whether the linking device and the host PC are in the same subnet. Otherwise, the linking device will not be detected.

    Hi Nancy,
    If you keep the entire iTunes folder as it was and you're still using the same platform, you'll be able to keep all your playlist and metadata.

    Well, iTunes will only transfer content from the computer to your iPod. However, there's some ways to get around this. Read this carefully:
    If you have purchased songs from the iTunes Music Store, then those are pretty easy to transfer to your computer. You'll just need to follow [this instructions|http://docs.info.apple.com/article.html?artnum=305465].
    All your other songs (for example, those ripped from your CD's), you'll need to use any 3rd party program to transfer them to your iTunes library!
    Some can also transfer your playlists, videos, ratings, podcast...

    Hi,

    Thanks for the reply,
    It used to be the same metaset name on the second server, which several folks have run into when installing SC on the 2nd node. So I renamed it when booted into no cluster mode using metarename. I then updated the /etc/vfstab with the new name, this is it in /etc/vfstab:
    /dev/md/dsk/d26 /dev/md/rdsk/d26 /global/.devices@2 ufs 2 no global
    And yes if I change "global" to "-" then it mounts. When the 2nd node boots up, it cannot mount /global/.devices@2 with it set to global so the boot halts, I do ctrl-D to continue. Then I try a regular mount from root and I get the "no such file or directory" message.
    If I do a metastat d26 it shows it to be OK on both submirrors.
    The name of the metadisk on the first node is d160. And the 2nd server is able to mount that from the global option on the first server.
    Thanks,

  • Linked devices

    I would be very grateful for some help please. I have a BB Q10. I've been trying to install the latest version of BB Link on my laptop. At one point in the process, I get a screen that reads "LINKED DEVICES This BlackBerry ID isn't associated with a device running BlackBerry 10 OS or there was an error accessing your information". I now get the same message if I use the previous version of BB Link. I don't understand what's going wrong. My BB ID is live and kicking and has been for ages. It's the same ID as on my Q10. I haven't mistyped my username or password. I've even reset my password thinking that might have got corrupted somehow.  I've signed out of my BB ID and then back in. I've closed BB Link and opened it again. I've tried every help topic I can think of on the various BB help sites/pages but without any success (that may be because I'm being inept, of course). I've tried uninstalling BB Link on my laptop and then reinstalling it -- disabling my antivirus programme first in case that's interfering with it -- but again without success. If anyone has any bright ideas of how to solve this problem, I'd be very grateful. Thank you.

    It's not so simple to add a new BBID to the Q10.. it requires a security wipe of the device.
    Try this however, in your Settings > BBID. Edit and make some small change of your First or Last name or even the security question used, and save.
    Then let's see if that reconnects your device to the BBID.
