Issue 1.4

No further settings have to be made in ibaPDA.

As soon as ibaPDA receives PTP telegrams, the BMCA (Best Master Clock Algorithm)
determines the best timer in the network and synchronization is carried out.

Note

When using PTP, please observe the requirements for the network and the built-in com-
ponents.

Refer to chapter 15.2
