Process Data Objects (PDO)
PDOs (Process Data Object) will be used for I/O exchange. PDOs are mapped to objects during configuration (PRE-OPERATIONAL state).
TxPDOs are used to transfer data from the option card and RxPDOs are used to transfer data to the option card.
The module supports at least 8 parameters mapped to RxPDO and 8 parameters mapped to TxPDO.
PDOs and Default PDO Setup
The drive supports 15 Receive and 16 Transmit PDOs. The tables below show available PDOs, their default settings and the objects required to set
up when changing the PDO configuration or the PDO mapping.
Transmit PDOs (TxPDO)
The Transmit PDOs have a default mapping according to the table below. The transmit PDOs can be re-mapped by the end user by writing to map
objects 0x1A00-0x1A28, please see
Communication Profile Objects (DSP 301) on page 18
Receive PDOs (RxPDO)
The Receive PDOs have a default mapping according to the table below. The end user can re-map Receive PDOs by writing to the map objects
0x1600-1628, refer to
Communication Profile Objects (DSP 301) on page 18
