General safety instructions
Warning
Disregarding the safety instructions can result in death,
serious injuries or major material damage.
Observe the safety instructions and warnings.
Refer to the brief description for technical safety
requirements èP.BE-CPX-F8DE-P-...
Note
Electronics modules include electrostatically sensitive
devices. Incorrect handling can cause damage to the
electronics modules.
Observe the handling specifications for electrostatically
sensitive devices.
Discharge static electricity from your body to protect the
modules before assembling or disassembling modules.

Intended use
The input module CPX-F8DE-P is intended for reliable
recording and evaluation of signals of connected sensors.
The input module provides up to eight secure inputs that can
be used by a higher-order safety controller in a safety
function. The communication with the higher-level safety
control is implemented by the safe PROFIsafe protocol via
aPROFIBUS or PROFINETIO fieldbus connection.
The inputs on the input module can be combined for
multi-channel sensor applications. Every two inputs form a
channel pair, which is set separately with one of 11 function
modes. The function modes influence the evaluation of input
signals and optionally the generation of clock signals.
The characteristics of the inputs comply with standard
IEC611312 for Type 2 digital inputs.
The input module CPX-F8DE-P is a product with
safety-relevant functions. The input module is intended for
installation in machines or automation-technology systems
and may be used only as follows:
– in excellent technical condition
– in its original condition, without unauthorised
modifications
– exclusively in the configurations specified in this
description èChapter1.3.3
– within the limits of the product as defined by the technical
data èAppendix A.1
– in an industrial environment

Note
The use of the input module CPX-F8DE-P for
implementation of safety circuits is not permissible in the
following cases:
 in a CPX terminal equipped with CPX-FEC or CPX-CEC
 in a CPX terminal of variant P
 in configurations other than those listed
èChapter 1.3.3, Function modes.

Achievable safety rating
The CPX-F8DE-P can be used to implement safety functions
up to:
– Performance Level e, Cat. 4 in accordance with
ENISO13849-1
– Safety Integrity Level SIL 3 in accordance with EN61508
– Performance Limit SILCL3 in accordance with EN62061
The attainable safety classification of the overall safety device
depends on the set function mode as well as other
components used to implement the safety function.
Make sure that the overall safety function of the system is
analysed and validated.
It is the responsibility of the operator to determine and
verify the required safety classification (safety integrity
level, performance level and category) of the system.
Be aware of the residual risks that remain in your system
despite the measures to integrate safety in the design,
despite safety precautions and despite the
supplementary protective measures.
The residual risks are determined, among other things,
byyour safety regulations and the safety characteristics
of your system.

Information on compliance with a safety classification
Test the functionality of the safety device at adequate
intervals.
Recommended:
 at least 1x per year for PLd
 at least 1x per month for PLe
The operator is responsible for selection of the type of test
and the time intervals between the tests.
Conduct the tests in order to ensure that the smooth
functioning of the safety device is verified and
documented in interaction with all components.
Ensure that, after each safety request due to
aself-diagnostic test, the system undergoes
troubleshooting and a restart under the supervision
ofthepersonnel responsible.

Failures due to a common cause (Common Cause Failure – CCF)
Common cause failures cause the loss of the safety function,
since all channels in a multichannel system fail
simultaneously.
The following measures ensure that common cause failures
are avoided:
Comply with operating voltage range
Comply with signal voltage range
Comply with temperature and environmental conditions
The application may result in additional measures to avoid
common cause failures.
