Hi Wolfgang, The problem is that the MN and CN xdd files in the folder: ...\apps\common\openCONFIGURATOR_projects\Demo_3CN\deviceImport have not been updated since v2.1.1 even though the support for REAL32 was added long time ago. If one uses the MN and CN xdd files in the respective folders: ...\apps\common\objdicts\CiA302-4_MN & ...\apps\common\objdicts\CiA401_CN then everything will work fine. In the future releases, it is important to make everything consistent. Otherwise, if one uses the xdd...

Hi, I am trying to modify the demo programs to send real32 data between MN and a CN. I read the posting: https://sourceforge.net/p/openpowerlink/discussion/newbie/thread/10a06574/ and made the following changes: (1) add real32 support for managed node by changing objdict.h (2) add object definition for controlled node by changing objdict.h (3) add real32 support to xdd file of managing node (4) add object definition to xdd file of controlled node I also ran openCONFIGURATOR and copied the xap.h and...

Hi, With "./plkload oplk82573mn.ko", we could get: "module verification failed: signature and/or required key missing -- tainted kernel". It is not documented how to overcome this. Can you share with me what is the best way around this? Thanks, Simon

Hi, I did "./plkload oplk82573mn.ko" with no errors. I also did "lsmod" to make sure oplk82573mn.ko is loaded. But there is no /dev/proc directory although /dev and /proc exist independently. Where exactly should I be looking for this file? I tried finding anything named "oplk82573" will no success. Thanks, Simon

Hi Christoph, Thanks so much, that did the trick. I have decided to use your option 1 by defining a struct in the ApplicationProcess/dataTypeList for my messages. I have 2 questions: (1) Using your struct.xml example, can you tell me what is the corresponding changes I need to make to the CN objdict.h file? (2)How do I link the process variables to the object dictionary? Can I still use the "tOplkError oplk_linkProcessImageObject" function with "varEntries" set to 1? Thanks again so much for your...

Hi Christoph, Thank you very much for your quick response. I tried out the struct.xml file by inserting it in a standard CN.xdd file and pass it to OC and was able to build without problems. However, I couldn't get group.xml to work. BTW, I modified your group.xml file to ensure Byte field enumeration is consistent. See below. Here are the errors that I have encountered: (1) If I insert the following before the <Application Layers=""> line, I got "Content is not allowed in prolog". (2) If I insert...

Hi Romain, Sorry I did not see your suggestions till today. I weant to: EclipseFolder$\plugins\org.epsg.openconfigurator_2.2.1.201708040602\os\linux\x86_64 I tried the symlink as you delineated and it did not work. Same problem: "Error loading shared librariess - no boost_date_time in java.library.path." Any ideas? Thanks, Simon

Hi, My understanding is that it is possible to have a maximum of 0xFE x 0xFE mapped objects per direction. But currently in openCONFIGURATOR , there is only 1 TPDO and 3 RPDO for a CN, this means 254 objects for TPDO and 3x254 objects for RPDO. So how can I get pass this limitation? Thanks, Simon
