You can use the second interface on the CPU 948 (SI 2) as a PG
interface in exactly the same way as the first interface.
To be able to link your PG via this interface, you must also order the
PG interface module in addition to your CPU 948 (the order number is
listed in the system manual 135U/155U /2/).

All the PG functions are available on both interfaces. The following
sections contain only the information that you require if you work
with PGs or OPs on both interfaces simultaneously.
