EtherCAT Chassis Temp

Does the EtherCAT chassis provide any way to monitor the chassis or processor temperature in either Scan Mode or FPGA mode? I know devices like PXI and CRIO allow you to monitor the CPU and Chassis Temperature respectively but I'm wondering about the EtherCAT.

Hi craige, 
At first read I thought you were asking for scan engine supported solutions. You can return the temperature with a udv but you have to create an FPGA vi to do so however, 
There is an IO variable on the FPGA when you create it called "chassis temp." simply pipe that variable to an appropriate UDV. You might check the examples also, I thought one of them showed how to do it.

  • KT6V Chassis Temp Sensor?

    Anyone know where the KT6V LSR chassis temp sensor is? I am sitting here running Prime 95 on a new watercooled rig. Ambient temp si 22 C, motherboard monitor is reporting the chassis temp at 35C and the CPU at 38C. I love the fact that the CPU is this low under 100% stress, but cant imagine why the chassis is reporting 13 degrees over ambient. There is a fan blowing air on the mosfet and caps next to the cpu to keep them cool.

    Did not expect to get to ambient. That was not my question. If you reread the original post, I am trying to determine the location of the sensor on the motherboard that reports the chassis temp. I am more than happy with my cpu temp of 38 C. I am trying to figure out why the chassis is reporting so high with the side off the case, and I have one case fan blowing on the area between the cpu and io plate to cool mosfets and caps since there is no wash now coming off of any cpu air cooler.

  • Sudden temp rise at idle

    i reseated my heatsink today cause i took the mobo out to see if a mod idea would work.  i put it back on same as i've always done except now my cpu temp is almost 10 degrees hotter.  it's around 62-63C idle and i think that's much too hot.  you can see in my sig what it used to be.  any ideas on what might be causing this sudden rise?  even with the case open the temp remains high.  
    believe it or not my chassis temp is actually lower by about 2-3C.  i did move a fan so that might be causing the chassis temp drop but i don't think it would cause a ten degree drop even with the case open.

    there has been one chip since forever but there are newer ones.  with my old hsf i put it on wrong once so it may have caused a small chip and then with the amount of pressure it takes to put my volcano 9 on it may have grown a bit.  the chips i am talking about are very small.  one corner that has always been chipped is about the size of a pin head.  the longer chip that has grown a bit is along the opposite edge starting at the corner and travelling about 4mm along the edge.  and it's only about 1 mm deep.
    for now i have it unoverclocked and it's running at 56C idle which is still much higher than the 49C idle it used to be when unoverclocked.  i will try reseating again in the morning.  it's a pain to do cause the way my power supply is situated i have to take the whole mobo out which means disconnecting everything.
    i just checked my vid card temp and oddly enough it's at like 48-49C idle when it used to be at 42C idle and 46C full load.  since i unoverclocked, my chassis temp has dropped 3C.  do you know where the temp gauge is for the "chassis"?  don't think the vid card temp is related but it's just odd that all my temps are acting kooky.

  • Stop FPGA execution in Ethercat

    Hello
    I would like a piece of advice about how I can stop the code execution in FPGA in etherCAT chassis. I work on a piece of code where I start the VI in a RT computer and the FPGA produce PWM puses with a difital module. However, stopping the main VI, the FPGA is still working giving pulses with the NI module. I'm trying to send a stop command from the main VI to the FPGA without success. Is there any specific type of command to communicate with the FPGA in etherCat ?
    Note that the initial code is not made by me, so I don't have fully control of it.
    Thanks for any help !

    Hi TapTap
    Do you have both the RT code and FPGA code?
    I'm a little unsure from you post if you only have the RT side and can't change anything on the FPGA? 
    Normally you could just use a User Defined Variable and hook it up to the FPGA and RT side (remember to compile the FPGA), and remember to initialize it to false at beginning of execution)

  • EtherCAT FPGA master-sla​ve

    Hello
    I am using two NI9144 EtherCat chassis conncected to a RT desktop. I have one FPGA VI running on the master and  doing some acquisition. As far as I've understood from some NI documents, there is FGPA available in each chassis. However, I want to use also the modules which they are on the slave chassis. I tried and the I/O nodes can be dropped and work only in the FPGA that they belong to, which sounds logical. So my question is : Should I have separate VIs for the acquisition in FPGA mode at each chassis ? And if yes, how I can ensure synchronized measuremenets form the different I/O modules ?
    Thanks

    If you just need high usec resolution (~10 kHz) you may be able to run the ecat network that fast, depending on your host controller (ie a PXI should be able to hit that, a 9074 definitely wont). However this will be relatively poor synchronization compared to an actual signal based approach. 
    If you have DSA modules the 9469 (http://sine.ni.com/nips/cds/view/p/lang/en/nid/210​832) may be appropriate. Its still signal based synchronization but it will keep all of your DSA modules in sync together, which means that if they all have the same sample rate you could in theory keep a running counter on your host, latch the counter value when you see or generate the digital trigger (lets say you see the trigger at analog sample #58209), transmit that over ethercat and have a memory on the 9144 which holds N previous samples. With a bit of math you might be able to set it up to retrieve the AI value at a particular sample count.
    But honestly this sounds pretty hard. There are probably better solutions out there. If you haven't already, I'd recommend talking to the sales rep for your area or calling into ni support to discuss your application in more depth and figure out the right platform for your needs.

  • Difference in temp pc alert / fuzzy logic

    I use pc alert 4.0.0.9 and fuzzy logic 4.1.4.9 with a k7t266 Pro mainbord. When comparing the CPU temp. fuzzy logic always shows a temp wich is always 5 degrees higher compared to the temp pc alert shows. Which one is to be trusted ?

    Ok, the difference between the bios temp and the PC Alert temp (5 degrees) could be explained by running windows when checking with PC Alert; so nothing to be afraid of.
    But now I've a question about speedfan; I downloaded/installed the programm as some of you suggested but wonder if it runs as it should..
    The temp values which are showed are confusing...
    two of them are NEGATIV !-->
    temp 1 winbond W83627HF 43 degrees
    temp 2 idem 46 degrees
    temp 3 idem -47  degrees
    temp LM75 -47 degrees
    temp LM75 46 degrees
    Also I wonder how to discover which temp value is the cpu; I believe the temp1 winbond is the chassis (it's the same value as the chassis temp in PC Alert 3) ? The speedfan faq/help only shows how to rename the values but not which one is which...  (cpu temp according to PC Alert 3 is 50 degrees)

  • Northbridge temp? my fan broke so now im using a passive

    My nortbridgefan broke so i installed a Zalmann passive but there is no tempsensor for nb.
    So im using my chassi temp-diod and it says that the passive heatsink is around 60c(130f), Its that ok?

    freeman_swe , What are your system specs ( see my signature as an example of what we need to see)
    I know on the 865/875 series boards the northbridge does not have a temp sender . The readings that people report seeing are just stray voltage that is being converted into a reading by the board
    I am betting that this is the same in your case as you state you are seening temps in the range of 60c which is what I see also
    Don't worry about it , you northbridge will work fine with a passive cooler attached

  • Temp on my K74V with a XP2200

    I have a xp 2200 in a k74v mobo and de temperature is 54c on cpu, 32C on Mobo.
    Is this ok?
    Thanks a lot

    If your chassis temp is 32C your CPU temp should be somewere between high thirties and low forties.
    What heatsink and thermal compound do you have? Maybe it's time to redo/change something?

  • Power off before swapping EtherCAT hardware?

    NI has provided the ScanEngine API to allows user's the ability to discover C-series and EtherCAT chassis dynamically and I really like it. This allows me to "hot swap" hardware and my software can just adapt dynamically based on the discovered modules. Is turning off my etherCAT chassis prior to doing this recommended anywhere?
    In otherwords, I like the idea of putting the ScanEngine in Configuration Mode then pulling out C-series modules and replacing them with new ones without powering off the chassis. Could this potentially harm my hardware? Does NI strictly advise against this?
    Thanks,
    Craig

    Hi Craig,
    NI CompactRIO is a small rugged industrial control and acquisition system, and all the NI C-Series modules used in this system are hot-swappable industrial I/O modules. That’s being said, when using a CompactRIO (no matter it’s a cRIO controller or an expansion backplane like NI 9144 EtherCAT slave chassis) with modules in the slots, it is NOT necessary to power down the device.  CompactRIO was designed with this feature in mind.
    A slight deference a CompactRIO RT Controller (e.g. NI 9074) and NI 9144 is that, when you swap (even an identical) C-Series IO module on NI 9144, the slave device will report an emergency data to your host system, which might disturb your system if it’s running. The emergency will disappear when you manually or programmatically switch Scan Engine to Active Mode again. But anyhow, this is all for software side; it will not harm your hardware.
    Hope it answers your question!

  • Is it possible to generate a PWM using Veristand, PXIe, EtherCAT 9474 Digital Out Card without creating a custom FPGA?

    I am looking to generate a PWM signal and I have done so using Veristand and a 9474 in a CRio.  There is an option in the Veristand System Explorer, when the 9474 is selected, labeled 'Specialty Digital Settings' and gives a PWM option. However I now have a 9474 in an EtherCAT slave and the 'Specialty Digital Settings' no longer appears in the Veristand System Explorer.  I am somewhat new to using Veristand and have little to no LabView experience, and I am looking for a way to do this without creating a custom FPGA with LabView.
    Thanks!

    Hi PMC_NIU,
    Unfortunately, the Specialty Digital mode is not supported by the EtherCAT chassis.  However, creating an FPGA VI to create a PWM signal is relatively easy, and there are a lot of examples that can help you get started.  The Developing a PWM Interface using LabVIEW FPGA tutorial is a great place to start.

  • Pulse counting on EtherCAT

    How does one read the data from a digital pulse counter card (9411) on an EtherCAT chassis (9144) FPGA from real-time on a PXI system? As far as I can tell, EtherCAT FGPA does not support DMA FIFO or reading front panel controls.

    The 9144 chassis does not support specialty digital either so you need to implement the counter on FPGA and transfer the data with User defined variables from FPGA to RT. Luckily that's done in an example already shipping with the driver.

  • NI 9237 External Excitation - VeriStand 2013 SP1

    The recommended excitation voltage for my pressure transducers is + 10 VDC. I prefer to use external excitation as per the NI 9237 manual, total power for the module is limited to 150 mW, which in my case is "Four 350 ohm full bridges at 3.3 V". (I will be using (4) full bridge 350 ohm pressure transducers). I am using Scan Engine for EtherCat and have the NI 9237 in a NI 9144 Chassis connected to a cRIO-9081. For troubleshooting, I have two transducers on a pressure calibrator and another RJ50 connection to a NI 9949 breakout. If I select "External Excitation" and have my 10 V power supply connected to the lower EX+, EX- connector, I get an invalid value for my pressure transducer. This is after scaling the value in calibration. The Raw Value is also incorrect. If I leave it set to "External Excitation" but pull the EX+, EX- connector, the EX+, EX- voltage (pins 6 & 7) will go to 4.735 V and I will get a CORRECT pressure reading. If I select Internal Excitation of 3.3V, I will get a correct pressure reading, but I am a little concerned about resolution as the recommended excitation is + 10 VDC for the pressure transducers. My question is: why am I unable to use the external excitation? I have another application with a PXI and EtherCAT chassis and it works OK. I've also tried placing a NI 9237 module in the cRIO-9081 chassis and get the same invalid value that I describe above.
    Solved!

    Do you have the latest version of the Scan Engine and EtherCAT custom device? On the community page for this custom device, the latest bug fix listed specifically refers to this module. Also there is a specific forum for this custom device that it may be a good idea to post on as well if you have not already posted there about this problem.

    Hi sachsm,
    The error appears to be related to a low level problem with the EtherCAT driver. Are you connecting from your cRIO to an EtherCAT chassis? If so, what version of that that driver (NI-Industrial Communication) are you using?
    Can you upgrade to the latest version of that?

  • MIB in Solaris 8

    Hello,
    Our servers are currently monitored by a variety of services (HPOV, WUG, Netcool). There is no environmental monitoring currently performed. Environmental would include failed power supplies, hot of non-functioning fans, excessive chassis temp. There's something similar for Cisco like:
    traps for environmental problems are:
         (config)#snmp-server enable traps envmon ?
    fan Enable SNMP envmon fan traps
    shutdown Enable SNMP environmental monitor shutdown traps
    status Enable SNMP environmental status change traps
    supply Enable SNMP environmental monitor supply traps
    temperature Enable SNMP environmental monitor temperature traps
    The question here's. I know is something in Solaris 8 (MIB) that can trigger or tell us something of that kind of environmental issues, how could we setup or compile a MIB or MIBS so everytime those issues come out, we get a notification email for instance?
    Thanks for any time and/or consideration you may have afforded my message
