8.3 Object 1003h: Pre-defined error field
This object saves the measuring system error occurred last and displays the error via
the Emergency object. Each new error overwrites an error which was stored before in
sub-index 1. Sub-index 0 contains the number of the occurred errors. Meaning of the
error codes see Table 11, page 61.

Sub-index 0: The entry at sub-index 0 contains the number of errors that have
occurred and recorded in sub-index 1.
Sub-index 1: The error are composed of a 16 bit error code and a 16 bit additional
error
information.

Additional Information
8.4 Object 1005h: COB-ID SYNC message
This object defines the COB-ID of the Synchronization Object (SYNC). Further, it
defines whether the device consumes the SYNC or whether the device generates the
SYNC. However, the measuring system supports only the processing of SYNC-
messages and uses the 11-bit identifier.

Bit 29
= 0, 11-bit ID ( CAN 2.0A )
Bit 28 –11 = 0
Bit 10 – 0 = 11-bit SYNC-COB-IDENTIFIER, default value = 080H
If a SYNC-telegram with the identifier, defined in this object (080H), and data
length = 0 has been received by the device, the position value of the measuring
system is transmitted by the 2nd Transmit PDO (object 1801h), non-recurrent
triggering.
