First you must tell us how you would like to have time to flow through the system.
There is no golden config that fits all. Tell us your requirements - paint us a map of your system and how time should flow through it.
- Shall a controller be clock master, what controller, what networks does it use?
- Shall more than one control network or controller brand/family be synchronized?
- Shall an external clock be used, where is it located?
- Shall the system slave to an external domain or office network time?
The Automation System Network guide, 3BSE034463R5021 contains all info you need.
Whatever configuration you choose, ensure that no node SLAVE to more than one clock sync protocol (as it may cause time jitter/oscillation).
Its perfectly OK to act both as slave and master, even acting as master for multiple time protocols at the same time, but just don't activate more than one (1) client protocol at a time and node.
Do also search for your topic of interest, this forum contains a large amount of threads - maybe your problem is already answered? E.g. have a look at this one (and there are certainly more to find if you seek...):
