• cRIO is unable to enter active mode, because of the ethercat slave

  I have a (CS27 of HBM) ethercat slave connected to a cRIO 9068. If I right click on the device HBM under the EthercatMaster and go to 'Device status online' I put first the State of the HBM "Operational Pre", "Operational security" and then "operational." The CX27 indicates the operational stae with a LED.

  But when I try to put the cRIO in "active" Mode I get the error message:

  -The analytical engine NOR could not be changed to active mode, because one or several devices to find could not access the operational mode.

  The problem is finally solved.

  The problem has been layout of different synchronization between the HBM and cRIO (801 vs 802) Manager.

  Thanks to HBM to provide a firmware update to take in charge the provision used by OR!

• AOP of EtherCAT Slave not load completely from XML file

  Hi all

  I'm trying to import an XML file of Beckhoff device profile for the EL 6695 EtherCAT Slave in the LabVIEW project.

  I brought changes to the Beckhoff as XML files so that all the 'user-defined AOP"is also included, when I connect this slave of my LabVIEW project.

  Screenshot below will give you an idea on my LabVIEW project.

  

  In the screenshot, you can see the entries of the AO responsible for the EL 6695 ethercat slave.

  The main problem here is that entered the AOP list / output entered is incomplete. I have 100 + entries "Of DDR" and even outputs.

  Please let me know if anyone has an idea about this.

  Thanks in advance!

  Hi Raul,

  Sorry for the end frequency! China observed holidays these days.

  Finally, I found the cause of this problem! It's because of the extra 'space' behind the text of the name of the entry.

  

  If all the entries after the entry of this issue will be ignored by LabVIEW. LabVIEW currently has some limitation to detect this. I go to your comments this problem to the right team to solve this problem in the future! Please see the attached XML, I modified according to your version.

  Sorry to have caused you so much pain because of this!

• Part 3 EtherCAT Slave: importing XML Device Profile succeeds on host but fails on the target

  Hello

  I'm trying to control a 3rd party via EtherCAT servo drive:

  • Master: NOR-cRIO 9024
  
  
  • Slave: Beckhoff AX5203

  I downloaded the files of unit on official website of Beckhoff Description: http://www.beckhoff.com.au/english.asp?download/elconfg.htm (Beckhoff_EtherCAT_XML.zip)

  I followed the instructions to http://digital.ni.com/public.nsf/allkb/FDA1318A8909D02C862574510060DB62 to import the profile description of the device.

  Curiously, the import was successful for the host (and I can now access this device in the LabVIEW LVPROJ file), but it failed for the target.

  Why could this be? (There are no diagnostic messages)

  

  Hi JKSH,

  Looks like you are using NOR-Industrial Communications for EtherCAT 2.7 or later. What is you project connected to the target when you try to import the file? How are you connected to the target? What is your firewall block FTP transfers? Do you need the ability to programmatically discover slaves EtherCAT (such as DSM or using the VI of Modules Refresh)? If you just want to program the EtherCAT Slave in the LabVIEW project, import the device description files to the host is all that is needed.

  Best regards

• Servo on EtherCAT: parameter invalid when going from pre-op to SafeOp

  Hello

  I'm trying to control a 3rd party via EtherCAT servo drive:

  • Material:
  
  
  • Master: NOR-cRIO 9024
  
  
  • Slave: Beckhoff AX5203
  
  
  • Software:
  
  
  • LabVIEW 2013 SP1 (32-bit)
  
  
  • OR-Industrial Communications for EtherCAT 2.7

  Use of the test panel LabVIEW (see image below), I am able to switch the slave between Bootstrap, Init, and States pre operational. The LCD screen on the slave displays the correct States I selected, so I know the basic EtherCAT link works.

  However, when I try to transition from pre operational to the safe working condition, I get an error.

  • LabVIEW, said 'the slave can not move to the specified state' (see image below)
  
  
  • Display LCD slave displays error 0xF4A5, which, according to the website of Beckhoff , is "a parameter error has been detected in the SoE communication layer"

  

  I'm at a loss at how to begin troubleshooting.

  The explanation of the error says "go to the status page of the device your device online and check errors and emergency unit data. However, I find no error or given emergency in the Online slave device status page. There is that the "EtherCAT: online: State" and "EtherCAT: settings ' (picture above).

  I wonder if this problem is related to any of the following:

  • Import the XML device profile was not entirely successful. I described this to http://forums.ni.com/t5/Motion-Control-and-Motor-Drives/3rd-party-EtherCAT-slave-Importing-XML-Devic...
  
  
  • My "EtherCAT: settings" page is empty, there is nothing in the dictionary of the object.

  Advice would be greatly appreciated!

  Hey,.

  Obviously, NEITHER was able to get the ability to work with Beckhoff and supports so that officially AKD. So regarding NI Industrial Communications for EtherCAT supports the SoE, see the reply to your other post on the forum.

• Play time of RT and EtherCAT

  Hello

  I have a NI 3110 industrial controller, which controls multiple NI 9144 EtherCAT slaves. Due to the drift to inherit the clock in the controller, I need to set the absolute of the Windows part of the program time periodocally. I do that with success using the VI 'RT Set time and date' of the pallet in real time. However, after setting the time on the controller, the 9144 chassis an error 2147137804 - "Master is no longer sync'd with the acting as slave the reference clock device". To get rid of it, the only solution I've found so far is to turn engine active scan configuration and return to active mode.

  Since this isn't a good solution to the problem, I wanted to know if there is a better?

  Thanks for any help,

  Christoph

  Open the rt.ini - or on your RT target and look for the following section:

  [TIME SYNCHRONIZATION]
  source. EtherCAT.Enable = TRUE
  source. EtherCAT.usable = TRUE
  source.ethercat.masterID = 0
  source_priority = ethercat;

  Change the first line
  source. EtherCAT.Enable = FALSE

  This will make the slaves are more to synchronize with the first slave. Instead, all slaves synchronize the master clock. See if this helps you in this situation.

• cRIO-9074 2147138533 error on active state transition analysis engine

  I have a cRIO 9074 configured as master EtherCAT.  The code for the RIO FPGA is followed by other data on the State and he is able to shut down all power to the rest of the system (including the EtherCAT slaves) for safety.  If I power cycle the cRIO (whose power to EtherCAT slaves Travel) I get the following error when it goes into active mode on the scan engine:

  Error 2147138533 has occurred to the property node (arg 1) in the updated scan engine Mode.vi-> RT Startup.vi system

  Possible reasons:

  The telegram is to expire.

  Check that the master device is connected to the EtherCAT network. Ensure that each slave in the EtherCAT network device is turned on and properly connected.

  Is it possible to start the engine even with the slaves turned off?  I just need to change my program to dynamically discover the slaves to stop the scan engine of faults on scan engine transitions?  I don't want to feed my slaves EtherCAT back on until I can read data that are currently being monitored by the scanning engine on the RIO even... is this possible somehow?

  Hello

  EtherCAT is tightly coupled with the analytical engine.  There is no way to set the active scan engine, while an EtherCAT Slave is disconnected.

  I recommend watching the following Article of knowledge-based programmatically discover and access EtherCAT.

• I can connect an NI MXI-Express RIO 9154 off the cRIO-9068 serial?

• Can I synchronize compactDAQ and cards for the generation M Series DAQ waveform continues non-regenerating in RT

  Hello

  I use a M Series DAQ card (6229) multichannel and multipoint make reading and writing of waveforms, all synced to a clock generated on the 6229.  Now I need to extend that to a "remote" (10 m) location and I was planning to use the Ethernet (9188 or 9184) CompactDAQ chassis or maybe 9144 Ethercat slave.  Before I have buy and learn the hard way, I thought I would ask some advice:

  My questions are:

  (1) using the DAQmx can I access the IO on 9184 or transparent 9144 using a multichannel multipoint DAQmx task as I do for the PCI 6299 card?

  (2) are all of these chassis supported if I use RT on the host?

  (3) is the best way to synchronize and trigger the remote system to the host using a digital line between the 6229 plug-in and the chassis from a distance, and if so, how can I connect it to the chassis and set it as a sample clock?

  Any help would be appreciated.

  Hi AnthonV-

  You make perfect sense.  And, I am pleased to report that you can program your analog output task CompactDAQ to use a clock timed by material, like your M Series device.  In fact, it is possible (and perhaps even likely) that the same code of OR-DAQmx you use for M-series can be used directly on CompactDAQ also long that the AO, relaxation and sources of timing and similar channels can be updated to point to your CompactDAQ chassis.

  As I've mentioned before, please note that only the CompactDAQ USB chassis (except the cDAQ-9172) are compatible with the PharLap LabVIEW RT objectives.  I don't know if this will meet your needs for a > extension of 10 m from the host system.

• EtherCAT: "found a module not supported on the slave device"?

  Hello

  I have a CompactRIO system that uses of slave hunts EtherCAT (cRIO-9081 + cRIO-9144) when I tried to deploy my settings, I got this message:

  Found a module not supported on the device slave address 0: 32445 slot

  What does that mean? (I have several slaves Garland, but of course, I don't have that many slot machines!) The chassis that has been reported with a red exclamation point contains these modules:

  • NI9201
  
  
  • NI9203
  
  
  • NI9265
  
  
  • NI9421
  
  
  • NI9481

  Is one of them unsupported on EtherCAT? If so, is there a list of modules taken into charge/no supported somewhere?

  Thank you!

  Hey there,

  I think you'd find this knowledge base, http://digital.ni.com/public.nsf/allkb/CA3A1D2166A4591386257514007A0F9C?OpenDocument , useful. It would be better to check what version of DAQmx you use and check the readme associated for compatibility or verify this DeveloperZone, http://www.ni.com/white-paper/10462/en. I hope this helps.

• cRIO-9074 ethercat with a switch/hub between the cRIO and slaves

  Hi, I have a cRIO9074 I'll use 7 JVL EtherCat Mac800 motor control.  Engines are fairly spaced, so I use a switch of CU2005 EtherCat Beckhoff 5 ports between the readers and the cRIO with 2 motors in series on three legs and a motor on a port by itself.  My problem is that labview will not find all engines unless one of the ports on the switch motor is plugged, or a line of engine is connected directly to the port ethercat cRIO.  He has no problem see two engines on the same line, it just will not see one of them if more than one line of motor is connected to the switch ethercat.

  Thus, HALP!

• Topology line EtherCAT with fiber/fiber converters

  Hello

  I have a request where I will order several NI 9144 slave chassis in a line of a master cRIO topology. The chassis must be 10kV + isolation from each other and the captain so I'll use converters of fiber on the link ethernet between each frame. The lengths of links are relatively short)<>

  Fiber converters does meet a particular specification, and if so do you have any recommendations?

  I'd better be using using standard Ethernet with NI 9149? I can cope without the deterministic calendar.

  Thank you

  Richard.

  Hi Richard,

  The EtherCAT protocol normally works on 100BASE-TX and can also run on 100BASE-FX (Sources here and here). I'm guessing that you have seen the KB that explains that you need for different cheating / hubs for EtherCAT and makes you wonder if the optical converters fall into this same category?

  The need for special switches / hubs is because EtherCAT junctions stars work differently that normal Ethernet as the packages hubs need a particular routing. However, optical converters online and do not affect the sense go packages. They are just bit conversion of the tensions light pulses. The main thing to consider would be how much latency converters to introduce network - as this will eventually affect your EtherCAT minimum cycle time.

  That said, NEITHER does not test the optical converters, but I've heard customers who use optical converters before (link sorry, not turned to the audience of reference available). As I mentioned above, the EtherCAT protocol specify how 100BASE-TX and 100BASE-FX, so I'll make sure the converter is in conformity with these standards.

• Third-party EtherCAT device

  Hello

  I want to use a Beckhoff EK1100 - slave EtherCAT in VeriStand. Unfortunately, I have absolutely no idea how to do that. As far as I understand that Scan Engine and EtherCAT only works for the cRIO-chassis.

  I've tried a bit with LabVIEW and am able to use the Beckhoff i/o modules in a LabVIEW vi. However, I don't know how to proceed.

  Kind regards

  TTRD

  In the meantime, I realized, what went wrong. The first error was that I just build Configuration and not the engine. The second error (screenshot from the last post) could be fixed connect via ftp to the target in real time and by removing the file/rt/or VeriStand/custom devices/Beckhoff EK1100. Now everything works fine. Oddly, my LabVIEW code wasn't the problem.
