11.8.1 Available process data objects
The number of available process data objects for controllers of the 8400 series depends on the
device version:
Receive PDOs (RPDOs)
The process data objects transmitted from the system bus to the drive are processed via the
LP_CanIn1 ... LP_CanIn4 port blocks.
• Every port block provides 4 words (2 bytes/word). The data of every first word are provided in a
bit decoded manner (bit 0 ... 15).
• The first word of the LP_CanIn1 port block is defined as control word wCtrl. The wCtrl control
word does not have a permanent connection to the device control and can be used as required.
The predefined assignment of the wCtrl control word in the C00007 = "30: CAN" control mode
depends on the technology application selected in C00005 :
• TA "Actuating drive speed":
Process data assignment for fieldbus communication ( 318)
• TA "Abschaltpositionierung":
Process data assignment for fieldbus communication ( 378)
Transmit PDOs (TPDOs)
The process data transmitted from the drive to the system bus are processed via the
LP_CanOut1 ... LP_CanOut4 port blocks.
• Every port block receives 4 words (2 bytes/word). The data of every first word are transmitted
bit by bit (bit 0 ... 15).
• The first word of the LP_CanOut1 port block is defined as the wState status word. The wState
status word does not have a permanent connection to the device control and can be used as
required.
• Vordefinierte Belegung siehe wDeviceStatusWord status word der Antriebsschnittstelle.
