9.6.1 Available process data objects
8400 BaseLine C controllers have a maximum number of 2 receive PDOs (RPDOs) and 2 transmit
PDOs (TPDOs).
Receive PDOs (RPDOs)
The process data objects transmitted from the CAN bus to the drive are processed via the
LP_CanIn1
and LP_CanIn2 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.
• For the predefined assignment, see the " Process data assignment for control via CAN " sub-
chapter for drive application.
Transmit PDOs (TPDOs)
The process data objects transmitted from the drive to the CAN bus are processed via the
LP_CanOut1 and LP_CanOut2 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 status word.
• For the predefined assignment, see the " Process data assignment for control via CAN " sub-
chapter for drive application.
