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
ƒ Description of COB-ID time stamp entry:
Bit Number Value Meaning
31 (MSB) 0
1 Devices does not consume TIME message
Device consumes TIME message
30 0
1
Device does not produce TIME message
Device produces TIME message
29 0
1
11-bit ID (CAN 2.0A)
29-bit ID (CAN 2.0B)
28 - 11 0
X 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.
