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
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
This limitation is defined by the XDD. To enable more mapping objects you have to add the respective 18XX / 1AXX objects for TPDO and the 14XX/16XX objects for RPDO. Additionally you have to adapt the PDORPDOChannels, PDOTPDOChannels and PDORPDOChannelObjects, PDOTPDOChannelObjects feature in the XDD. The XDD checker will check these values to verify the number of existing mapping objects.
You can have a look at the MN XDD because there are a lot more mapping objects existing.
