Festo P.BE-CPX-F8DE-P-E N en 1610a English
The input module CPX-F8DE-P is intended for use to reliably
acquire and evaluate signals of connected sensors.
The input module provides up to eight secure inputs that can
be used by a primary safety control unit in a safety function.
Communication with that primary safety control unit is per­
formed by the secure protocol PROFIsafe via a PROFIBUS or
PROFINET IO field bus connection.
The inputs on the input module can be combined for multi-
channel sensor applications. In each case, 2 inputs form a
channel pair that can be set separately with one of 11 func­
tion modes. These function modes have an influence on the
evaluation of input signals, and optionally on the generation
of clock signals.
The characteristics of the inputs comply with standard
IEC 61131­2 for Type 2 digital inputs.
The input module CPX-F8DE-P is a product with safety-related
functions. The input module is intended for installation in
machines or automated systems and may be used only as
follows:
– in excellent technical condition
– In original condition, without unauthorised modifications
– only in the configurations named in this description
è Chapter 1.3.3
– within the limits of the product defined by the technical
data è Appendix A.1
– in an industrial environment.
