Simatic communication ports isolation

Hi,
Does anyone knows if the MPI port, PROFIBUS port on a CPU S7-300 are galvanically isolated or not?
Also the communication port on the CP342-5
Thanks

Generally there are the following relationships between port type and isolation:

MPI=no
DP=yes
MPI/DP=yes

Notice that some S7-300 CPUs have ports that are MPI/DP and thus have both isolation and baudrates above 187.5k.
