What CAN IDs are occupied?

siliXcon device occupies CAN ID space for communication. The following tables show the CAN IDs used.

tip

• The protocol is not limited to the CAN bus. Other communication interfaces, such as USART, USB or Bluetooth may be used to access the device as well.
• In case of a conflict, you can turn off (or relocate) the parts of siliXcon protocol on the CAN bus (or any other interface), using the protoconf command.
• The number of address bits n can be changed with the msgconf command (CAN cfg2 parameter).
• The SID offset can be configured via protoconf SID remapping.

Use the controls below to recalculate the CAN IDs for a different addressing configuration. When the resulting CAN ID exceeds the standard 11-bit range (0x7FF), extended 29-bit CAN IDs are used (marked with EXT).

Find SID Offset From a CAN ID

If you know a CAN ID and want to derive the SID offset for SID 0, enter the CAN ID and the number of address bits below.

SID Offset From CAN ID

CAN ID:n (address bits):

Suggested SID offset for SID 0: 0 0x0

Address bits in the entered CAN ID: 0 of 7

SID offset = 0x000 >> 3

uint32_t bytes, little-endian: 0, 0, 0, 0

n (address bits):SID offset:

Group size: 8 (max 8 devices on bus) · CAN_ID = (SID << 3) + address · Standard CAN ID max: 0x7FF

Service protocol

The service protocol is used by all siliXcon devices to communicate with the SWTools.
