Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified

Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit
(http://www.siemens.com/industrialsecurity).
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use the latest product versions. Use of product versions that are no longer supported,
and failure to apply latest updates may increase customer’s exposure to cyber threats.

2.1
Application
The CPU 1516pro-2 PN is a component of the ET 200pro distributed I/O system in degree of
protection IP65, IP66 and IP67. The CPU provides you with maximum performance
combined with excellent usability. It is suitable for a variety of demanding applications and
communication tasks in automation engineering. It features:
●Integrated PROFINET interfaces
●Integrated Web server
●Integrated functionalities:
–Trace
–Motion control
–Closed-loop control functions
Integrated technological functions
The CPU supports motion control functions. STEP 7 provides PLCopen standardized blocks
for configuring and connecting a drive to the CPU. Motion control functionalities support
speed-controlled, positioning and synchronous axes as well as external encoders.
For effective commissioning and fast optimization of drives and closed-loop controls, the
CPU supports extensive trace functions.
In addition to drive integration, the CPU has extensive closed-loop control functions, such as
easy-to-configure blocks for automatic optimization of the controller parameters for optimized
control quality.
Due to the supported technology functions, the CPU is suitable for controlling pumps, fans,
mixers, conveyor belts, lifting platforms, gate control systems, building management
systems, synchronized axes, cross cutters, etc.
Security Integrated
The CPU provides, in conjunction with STEP 7, password-based know-how protection
against unauthorized reading out or modification of the program blocks.
The copy protection provides reliable protection against unauthorized reproduction of
program blocks. With copy protection you associate individual blocks with the serial number
of the CPU or SIMATIC memory card.
In addition, you can assign various access rights to different user groups using four different
authorization levels.
Through an improved manipulation protection, the CPU detects modified or unauthorized
transmissions of engineering data.

2.1 Application
CPU 1516pro-2 PN (6ES7516-2PN00-0AB0)
16 Operating Instructions, 09/2016, A5E35873416-AA
Safety Integrated
The fail-safe CPU is intended for users who want to implement demanding standard and fail-
safe applications both centrally and decentrally.
The fail-safe CPU enables the processing of standard and safety programs on a single CPU.
This allows fail-safe data to be evaluated in the standard user program. As a result of this
integration, the system advantages and the extensive functionality of SIMATIC are also
available for fail-safe applications.
The fail-safe CPU is certified for use in safety mode up to:
●Safety class (Safety Integrity Level) SIL 3 according to IEC 61508:2010
●Performance Level (PL) e and Category 4 according to ISO 13849-1:2006 or according to
EN ISO 13849-1:2008
Additional password protection for F-configuration and F-program is set up for IT security.
System diagnostics
Integrated system diagnostics is enabled by default for the CPUs. The different types of
diagnostics are configured instead of programmed. System diagnostic information is shown
uniformly and in plain text in STEP 7, on the HMI and on the Web server, even alarms of the
drives. This information is available in RUN mode, but also in STOP mode of the CPU. The
diagnostic information is updated automatically when you configure new hardware
components.

2.2 How it works
CPU 1516pro-2 PN (6ES7516-2PN00-0AB0)
Operating Instructions, 09/2016, A5E35873416-AA 17
2.2
How it works
The CPU contains the operating system and executes the user program. The user program
is located on the SIMATIC memory card and is processed in the work memory of the CPU.
The PROFINET interfaces on the CPU allow simultaneous communication with PROFINET
devices, PROFINET controllers, HMI devices, programming devices, other controllers and
other systems. The CPU 1516pro-2 PN supports operation as an IO controller and I-device.
IO controller
As an IO controller, the CPU 1516pro-2 PN sends and receives data from the connected
IO devices within a PROFINET IO system. You can operate the following IO devices on the
PROFINET interfaces of the CPU:
1st PROFINET interface (X1): maximum of 256 IO devices, of which a maximum of 64 in IRT
(Isochronous real-time).
2nd PROFINET interface (X2): maximum of 32 PROFINET devices
I-device
The "I-device" (intelligent IO device) functionality allows you to exchange data with an
IO controller. The CPU 1516pro-2 PN thus fulfills the role of an intelligent distributed pre-
processing unit of sub-processes. The I-device is connected to a "higher-level" IO controller
as an IO device.
Advantages:
●Interference-resistant configuration due to short signal and encoder wiring
●Reduced wiring effort for transmission of data via PROFINET

CPU 1516pro-2 PN (6ES7516-2PN00-0AB0)
Operating Instructions, 09/2016, A5E35873416-AA 19
Properties
The CPU 1516pro-2 PN has the following technical properties:
●Communication:
–Interfaces
The CPU 1516pro-2 PN has two PROFINET interfaces (X1 and X2).
The 1st PROFINET interface (X1) has three ports (P1R, P2R and P3). In addition to
PROFINET basic functionality, it also supports PROFINET IO RT (real-time) and IRT
(isochronous real-time). P1R and P2R are M12 circular sockets (with female contact
insert). They can also be used as ring ports for the configuration of redundant ring
structures in Ethernet (media redundancy). P3 is an RJ45 socket and is suitable, for
example, for connection of a PC, programming device or HMI device.
The 2nd PROFINET interface (X2) has one port (P1). P1 is an M12 circular socket
(with female contact insert). In addition to basic PROFINET functionality, P1 also
supports PROFINET IO RT (Real-time). IRT (Isochronous real-time) is not supported
by this interface.
Note
Special consideration when PROFINET IO communication is configured on the
2nd PROFINET interface (X2)
If you configure PROFINET IO communication
on the 2nd PROFINET interface (X2)
(operated as IO controller or IO device), additional system load occurs. You can find
additional information in the Cycle and Response Times
(
https://support.industry.siemens.com/cs/de/de/view/59193558/en) Function Manual.
Note
IP subnets
The IP subnets of both interfaces must be different. This means that the subnets of
the IP address of the two interfaces must differ from
each other.
●OPC UA
With OPC UA, data is exchanged via an open and vendor-neutral communications
