Safety Guidelines
Safety Guidelines
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
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
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 device/system may only be set up and used in conjunction with this documentation. Commissioning and
operation of a device/system may only be performed by qualified personnel. Within the context of the safety notes
in this documentation qualified persons are defined as persons who are authorized to commission, ground and
label devices, systems and circuits in accordance with established safety practices and standards.

Product Overview 1
Overview
This chapter provides information about the following topics:
● ET 200pro distributed I/O system with fail-safe modules and its place in SIMATIC S7 fail-
safe automation systems
● Components comprising the ET 200pro distributed I/O system with fail-safe modules
● The steps you must perform, ranging from selection of the F-modules to commissioning
of ET 200S on PROFIBUS DP/PROFINET IO
1.1 ET 200pro Fail-Safe Modules
Fail-Safe Automation System
Fail-safe automation systems (F-systems) are used in systems with increased safety
requirements. F-systems are used to control processes that can achieve a safe state
immediately as a result of a shutdown. In other words, F-systems control processes where
an immediate shutdown will not endanger humans or the environment.
ET 200pro Distributed I/O System
The ET 200pro distributed I/O system is a DP slave/IO device on PROFIBUS DP/PROFINET
IO that can contain fail-safe modules in addition to ET 200pro standard modules.
You can use copper cables to assemble the PROFIBUS DP/PROFINET IO lines.
Fail-Safe Modules
The primary difference between fail-safe modules and ET 200pro standard modules is that
fail-safe modules have a two-channel internal design. The two integrated processors monitor
each other, automatically test the input and output circuits and set the F-module to a safe
state in the event of a fault. The F-CPU communicates with the fail-safe module using the
PROFIsafe safety-related bus profile.
Fail-safe digital input modules record the signal states of safety-related sensors and send
corresponding safety message frames to the F-CPU.
Fail-safe digital output modules are suitable for shutdown operations with short-circuit and
cross-circuit monitoring up to the actuator.
Fail-safe switch acquires the signal states of safety-related sensors and sends
corresponding safety message frames to the F-CPU and is suitable for connection of
frequency converters, motors, and output modules.
Fail-safe connection modules are mounted on the fail-safe electronic modules. They are
used to connect sensors and actuators.

Possible Applications of ET 200pro With Fail-Safe Modules
The use of ET 200pro with fail-safe modules enables conventional safety engineering
designs to be replaced with PROFIBUS DP/PROFINET IO components. This includes
replacement of switching devices for emergency stop, protective door monitors and two-
hand operation.
Use in F-Systems
ET 200pro fail-safe modules can be used:
● In the S7 Distributed Safety F-system with the
S7 Distributed Safety V 5.1 or higher and
F-Configuration Pack V 5.4 or higher optional packages
The following manuals are applicable to the use of ET 200pro fail-safe modules in F-

The fail-safe DP master/IO controller exchanges safety-relevant and non-safety-relevant
data, for example, with the fail-safe and standard ET 200pro modules.

Application Limited to Safety Mode
You can operate standard and fail-safe modules simultaneously in an ET 200pro.
Fail-safe modules can only be used in safety mode. They cannot be operated in standard
mode.
Achievable Safety Classes
Fail-safe modules are equipped with integrated safety functions for safety mode.
The following safety classes can be achieved by assigning applicable parameters to the
safety functions in
STEP 7 with the S7 Distributed Safety or S7 F/FH Systems optional
package, combining certain standard and F-modules and arranging the wiring of the sensors
and actuators in a specific way:

Introduction
The following table lists all important steps required for commissioning ET 200pro distributed
I/O systems with fail-safe modules as DP slaves/IO devices on
PROFIBUS DP/PROFINET IO.
Sequence of Steps Starting From Selection of F-Modules to Commissioning of ET 200pro
Table 1-2 Sequence of Steps Starting From Selection of F-Modules to Commissioning of
ET 200pro
Step Procedure See ...
1. Select F-modules for ET 200pro
configuration.
Chapter "Configuration Options"
2. Configure and assign parameters for F-
modules in STEP 7 .
Chapter "Configuration and Parameter
Assignment" and "Fail-Safe Modules"
3. Set PROFIsafe addresses on F-modules. Chapter "Address Assignment and
Installation"
4. Mount ET 200pro. Chapter "Address Assignment and
Installation"
5. Wire ET 200pro. Chapter "Wiring and Assembly"
6. Commission ET 200pro on
PROFIBUS DP/PROFINET IO.
ET 200pro Distributed I/O Device manual
7. If commissioning was not successful,
perform diagnostics on ET 200pro.
Chapters "Diagnostics" and "Fail-Safe
Modules" and ET 200pro Distributed I/O
Device manual
Note
You must configure and assign parameters for the F-modules in
STEP 7 prior to
commissioning.
Reason:
STEP 7 automatically assigns the PROFIsafe addresses to the F-modules. You
must set these PROFIsafe addresses on each F-module via a switch before mounting the
module.

2.2 Allocation of Modules of an ET 200pro
Introduction
This chapter describes the assignment of F-electronic modules to F-connection modules for
ET 200pro.
Assignment of F-Electronic Modules to F-Connection Modules
You can use the following fail-safe electronic modules and connection modules together:

2.3 Limitation of Connectable Modules/Maximum Configuration
Maximum Number of Modules
PROFIBUS DP: The maximum number of modules in an ET 200pro depends on the
parameter length of the modules. A total of 244 bytes per ET 200pro are possible.
PROFINET IO: A maximum installation width of 1 m must not be exceeded.
Table 2-2 Parameter Length of F-Modules in Bytes
Fail-Safe Module Parameter length
8/16 F-DI DC24V PROFIsafe 42 bytes
4/8 F-DI/4 F-DO DC24V/2A PROFIsafe 34 bytes
F-Switch PROFIsafe 26 bytes
