SYNC (Synchronization Message) 

The COB-ID is fixed to 80h (CiA DS301 default value) and cannot be changed by the COB-ID Sync (1005.0H) obj. The SYNC message is useful in two cases:

• You want to retrieve PDOs from the drive only when requested by the master (SYNC producer)

• You want to ensure that PDOs sent by the master are processed by the drives at the same time
