4.1.3 Receive PDO Parameter and Mapping Objects
Object 0x1400 : Receive PDO Communication Parameter
This object is used to set the communication parameters of the RPDO.
Before changing PDO parameters, the PDO must first be disabled. Set bit 31 of the COB-ID to 1 (ex.: COB-ID
to 0x80000181). The parameters can then be rewritten. The PDO is enabled by deleting bit 31 of the COB-ID
(ex.: COB-ID back to 0x0181).
Subindex 0 indicates the largest supported subindex.
Subindex 1 determines whether the RPDO in question is used and defines its COB-ID.
Subindex 2 defines the Transmission Type of the object.
Value
Description Transmission Type
254
Asynchronous (manufacturer specific): asynchronous transmission
255
Asynchronous (device profile specific): asynchronous transmission
Subindex 3 describes the blocking time of the PDO with a resolution of 100 µs. Within this time after the PDO
has been sent, the PDO will not be sent again. For event-driven PDO, the bus load can be reduced this way.
Subindex 4 is not used (reserved by CiA).
Subindex 5 contains the event timer of the PDO, which defines the time intervals for the cyclic transmission
of the PDO.

Object 0x1600 : Receive PDO Mapping Parameter
This object contains information about the data to be received within the respective RPDO.
Subindex 0 contains the number of valid mapping entries.
Subindex 1 contains the 1st mapping entry. Dummy objects can also be mapped. They serve as placeholders
in the PDO.
Subindex 2 contains the 2nd mapping entry. Dummy objects can also be mapped. They serve as placeholders
in the PDO.
