3.2.1 Synchronisation with "Distributed clocks" (DC)
The "Distributed clocks" (DC) function enables an exact time adjustment for applications where
several auxiliary axes carry out a coordinated movement at the same time. The data is accepted
synchronously with the PLC program. In the case of the DC synchronisation, all slaves are
synchronised with a reference clock, called the "DC master".
