Siemens SIMATIC S7-1500R/H

Property Description Additional information
Supply voltage The 24VDC supply voltage is fed via a 4-pin plug located
on the front of the CPU.

PROFINETIO
PROFINETIO interface
(X1P1R and X1P2R)
The CPU has an X1 interface with two ports (X1P1R and
X1P2R).
• You use the PROFINETIO interface X1 (default set
tingP1R) to configure the PROFINET ring with the
two CPUs and the IO devices.
• You use the PROFINETIO interface X1 (default setting
P2R) to establish the connection between the two R-
CPUs within the PROFINET ring.
In the PROFINET ring, the synchronization frames
between the CPUs are transmitted via the following
connections:
– The direct connection (X1P2R)
– The indirect connection (X1P1R) 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
(backbone, router, Internet)
– Communication with another machine or auto
mation cell
PROFINET interface (X2P1) The CPU has an X2 interface with one port (X2P1).
The interface supports PROFINET basic functionality.
Operation of the CPUs as IO
controllers
IO controller:
As IO controllers the CPUs address the following con
figured IO devices:
• IO devices with S2 system redundancy within the
PROFINET ring
• IO devices with S2 system redundancy that are
decoupled from the PROFINET ring via a switch
• Standard IO devices (switched S1 devices)
Standard IO devices usually do not support H-
SyncForwarding.
To avoid a cycle time increase when the PROFINET
ring is interrupted, integrate the standard IO devices
behind a switch and not in the PROFINET ring.

H-Sync Forwarding
H-Sync Forwarding enables a PROFINET device with MRP to forward synchronization data
(synchronization frames) of an S7-1500R redundant system only within the PROFINET ring.
