Object 0x1012: COB-ID time stamp

This object defines the COB-ID of the Time Stamp object (TIME). It also indicates whether

the devices consumes or generates the TIME. The structure of the object is as follows:

MSB LSB

Bits 31 30 29 28 - 11

10 - 0

11-bit ID 0/1 0/1 0

000000000000000000 11-bit identifier

29-bit ID 0/1 0/1 1

29-bit identifier

 Description of COB-ID time stamp entry:

Bit Number Value Meaning

31 (MSB) 0

Devices does not consume TIME message

Device consumes TIME message

30 0

Device does not produce TIME message

Device produces TIME message

29 0

11-bit ID (CAN 2.0A)

29-bit ID (CAN 2.0B)

28 - 11 0

If bit 29 = 0

If bit 29 = 1: bits 28 - 11 of 29-bit TIME COB-ID

10 - 0 (LSB) X Bits 10 - 0 of TIME COB-ID

Bits 29 and 30 are static (unchangeable). The value of this object cannot be modified.

Writing the default COB-ID of the time stamp will not cause an abort code.
