A PDC doesn't have any FSMO roles, only an AD DC can hold FSMO roles and 
there are 7 of those:

SchemaMaster
InfrastructureMaster
RidAllocationMaster
PdcEmulationMaster
DomainNamingMaster
DomainDnsZonesMaster
ForestDnsZonesMaster

There is (as you can see above) a role called 'PDC Emulator' but this 
has nothing to do with a PDC.

The roles do not need to be all on one DC, in fact, if you have 7 DCs, 
you could have an FSMO role on each DC.

To see which DC holds which FSMO role, you can run on a DC:
