Festo — CPX-F8DE-P — 2022-10d
System overview CPX-F8DE-P
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
Malfunction during use of OSSD sensors on the manifold block CPX-M-AB-4-M12X2-5POL-T.
The connection of an FE contact to pin 5 on an M12 socket causes a short circuit. This causes
malfunctioning signals T1, T3, T5 and T7.
The input module reports module error 02: “short circuit 0 V at clock signal output T1357”.
• Connect the FE contact of a sensor only to the M12 plug screw connection of the module.
2.3.5
Channel bundling
Depending on the function mode in use, 2, 4, 6 or 8 channels can be grouped together to form a
channel bundle.
The input and qualification bits behave as follows within a channel bundle:
Status of the inputs
Input bits
Qualification bits of the channel
bundle
no error
0 or 1 (depending on the func-
tion mode and input signal)
1
Error
0
0
Tab. 21: Behaviour of the input data with channel bundling
If channel-wise passivation is not enabled, all input data bits are set to 0 if an error is detected.

Application examples
The creation of a safety function involves secure evaluation of connected sensors. The following
application examples in conjunction with 11 configurable function modes (
function modes) show you the different potential options for the intended use of the CPX-F8DE-P.
