Table 6.10 RxPDO mapping 22

0x1615

Receive PDO mapping 22

 

 

Sub-index 0: Number of mapped objects

 

 

Access: RW

 

Range: 0 to (CF)

Size: 1 byte

Unit: N/A

 

 

 

 

 

Default:

0

 

 

 

 

 

 

Description:

The number of mapped objects in thie PDO

 

Sub-indices 1 to 255: 1st to 255th mapped objects in this PDO.

 

Access: RW

 

Range: 0 to 0xFFFFFFFF

Size: 4 bytes

Unit: N/A

 

 

 

 

 

Default:

0

 

 

 

 

 

 

Description:

A mapping to an object with the following format:

 

Bits 0 to 7: Length of the mapped object in bits, e.g. a 32-bit parameter would have a length of 32 or 0x20.

Bits 8 to 15: Sub-index of the mapped object.

Bits 16 to 31: Index of the mapped object.

6.1.3TxPDO mappings

Objects with the indices from 0x1A00 to 0x1BFF specify transmit PDO mappings. The following mappings from DSP-402 are included as standard:
