Description
The CPU has an X1 interface with two ports (X1 P1 R
and X1 P2 R).
The PROFINET IO interface X1 (default P1 R) is
•
used to set up the PROFINET ring with the two
CPUs and the IO devices.
The PROFINET IO interface X1 (default P2 R) is
•
used to make the connection between the two R-
CPUs in the PROFINET ring.
In the PROFINET ring, the synchronization frames
between the CPUs are transmitted via the following
connections:
– The direct connection (X1 P2 R)
– The indirect connection (X1 P1 R) via the IO de-
vices
The interface supports PROFINET IO RT (Real-
•
Time) and PROFINET basic functionality.
Basic PROFINET functionality comprises:
– HMI communication
– Communication with the configuration system
– Communication with a higher-level network
(backbone, router, Internet)
– Communication with another machine or auto-
mation cell
The CPU has an X2 interface with one port (X2 P1).
The interface supports PROFINET basic functionality.
IO controller:
As IO controllers the CPUs address the following con-
figured IO devices:
IO devices within the PROFINET ring
•
IO devices that are decoupled from the PROFINET
•
ring via a switch
