1) Communication BACnet/IP, BACnet/SC: PXC4.E16-2 and PXC4.E16S-2.
Communication BACnet MS/TP: PXC4.M16-2 and PXC4.M16S-2.

2) For details on engineering, see PXC4, PXC5 & PXC7 Planning overview, A6V13054435.

3) KNX PL-Link data points do not count as integration points. For KNX PL-Link, only the limits on BACnet objects are considered.

4) The limitation is given by the maximum number of integration data points and maximum number of BACnet objects.

5) PXC4 has only limited Building X cloud connectivity. PXC4-2 has extended Building X cloud connectivity.

For more information about PXC4-2 automation stations, refer to the data sheets A6V14651312 and A6V14651900.
