CPU 1517H-3 PN (6ES7517-3HP00-0AB0)
Equipment Manual, 11/2022, A5E42011886-AD
Description
The 24 V DC supply voltage is fed via a 4-pin plug located
on the front of the CPU.
The CPU has an X1 interface with two ports (X1 P1R and
X1 P2R).
• The PROFINET IO interface X1 (default P1R) is used to
set up the PROFINET ring or PROFINET network (e.g.
line topology, mixed topology) with the two CPUs
and 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
The interface supports PROFINET basic functionality.
Die CPU has an X3 interface with one port (X3 P1) and an
X4 interface with one port (X4 P1).
The X3 and X4 interfaces are reserved for the synchroniz­
ation of the two CPUs.
Make the redundancy connections between the two
CPUs via the synchronization modules with fiber-optic
cables.
You plug each synchronization modules in the X3 and X4
interfaces.
You connect the two synchronization modules in pairs to
each CPU via a fiber-optic cable.
IO controller:
As IO controllers the CPUs address the following con­
figured IO devices:
• IO devices with system redundancy S2
• IO devices with system redundancy R1 (as of FW ver­
sion V3.0)
• Standard IO devices (switched S1 devices)
