[etherlab-users] EtherCAT newbie - NXIO 100-RE

[Fuchs Clemens]

 ethercat pdo is saying:

SM0: PhysAddr 0x1000, DefaultSize  128, ControlRegister 0x36, Enable 1
SM1: PhysAddr 0x1080, DefaultSize  128, ControlRegister 0x32, Enable 1
SM2: PhysAddr 0x1100, DefaultSize    4, ControlRegister 0x74, Enable 1
  RxPDO 0x1600 "RxPDO 1"
    PDO entry 0x2004:20,  3 bit, ""
SM3: PhysAddr 0x1358, DefaultSize    4, ControlRegister 0x30, Enable 1
  TxPDO 0x1a00 "TxPDO 1"
    PDO entry 0x2007:20,  3 bit, ""

but this is not, what is written in Hilschers XML and what sii_read is saying - why?

The device description generated by the master contains only basic information an can not be complete, because no all of the information can be queried from the slave. Moreover the generated XML contains PDO information read from the SDO dictionary.

If you are looking for the PDOs currently available, have a look at 'ethercat pdos', they are the same as in the generated XML file.
