System overview CPX-F8DE-P
NOTICE
Some function mode settings may restrict the manifold blocks that can be selected.
• Make sure that the manifold block required for the safety function is used.
NOTICE
The following applies for all applications of sensors and switches in combination with the corre-
sponding function modes of the input module CPX-F8DE-P:
The achievable safety integrity level, performance level and the category of your system are limited by
the component of the safety chain with the lowest characteristic value.
• Use only switches and sensors that meet the safety engineering requirements of the application.
• When using well-tried components in accordance with EN 13849-2, Table D.3, calculate the safety
classification from the manufacturer’s specifications.
The specifications of the switches and sensors include information on safety engineering considera-
tions and operating conditions.
NOTICE
Malfunctions at unused inputs are possible.
• Make sure that function mode 0 is always set for unused channel pairs.
For function modes with clock signals:
• Clock outputs T1, T3, T5 and T7 have the same clock signal.
• Clock outputs T0, T2, T4 and T6 run clock signals different from one another and compared to
T1/T3/T5/T7.
NOTICE
With bit-based programming of the function mode:
• Make sure that the mode switching is implemented within one PROFIsafe cycle. Otherwise there
may a short-term switch to a different function mode, which may cause unexpected reactions. Take
this into account in your application.
2.3.3.1
Function mode 0 – no signal evaluation
When switching on the input module, all channel pairs are in this mode by default. This function mode
is used for initial commissioning of wiring and sensors.
