4.2 CFU PA: Overview of the interfaces
The CFU is an IO device on the higher-level PROFINET IO system.
Interfaces
The CFU PA has the following interfaces:
Interface Quantity Supplementary note
Interfaces for bus systems:
PROFINET IO 1 connection
(terminal X5 of the
CFU for a BusAdapter)
BusAdapter with 2 ports (X1) for redundant connection to
PROFINET IO or forwarding the PROFINET IO.
Redundant connection is possible:
● Media redundancy (MRP)
● Singular system redundancy (S2)
The approved BusAdapter variants for connecting the
CFU to PROFINET IO are listed in section "Article num‐
bers (accessories / spare parts) (Page 181)".
PROFIBUS PA 8 fieldbus connections
FIELDBUS (FB<n>)
One field device per connection (FB<n>).
