3.2.6 Synchronization service
A SYNC producer sends the synchronization object cyclically as broadcast
telegram. The SYNC telegram defines the basic clock cycle of the network. The
time between the SYNC telegrams is set using the object Communication Cycle
Period (1006H). In order to obtain a precise (accurate) cycle between the SYNC
signals, the SYNC telegram is sent with a high-priority identifier (generally 80H).
This can be modified using the object 1005H. The SYNC transfer applies the
Producer/Consumer Push model and is non-confirmed.
