Properties 
CPU 1513R-1 PN has the following technical properties: 
 
All CPUs of the redundant system S7 1500R/H have a dis-
play with plain text information. The display provides you 
with diagnostic messages as well as information about the 
article number, the firmware version and the serial number 
of the CPU.  
You can also view and assign the IP addresses, the 
PROFINET device name and the redundancy ID of the CPU. 
The system IP address cant be viewed via STEP 7 but not in 
the display. 
In addition to the functions listed here, a large number of 
other functions are available on the display. These addi-
tional functions are described in the SIMATIC S7 1500 Dis-

(X1 P1 R and X1 P2 R) 
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 be-
tween the CPUs are transmitted via the following con-
nections: 
–  The direct connection (X1 P2 R) 
–  The indirect connection (X1 P1 R) via the IO devices 
•  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 (back-
bone, router, Internet) 
–  Communication with another machine or automa-
