System overview CPX-F8DE-P
2.3.1
Safe system status
Whenever an error is diagnosed in the input information for the module, the reaction depends on the
selected module operating mode:
–
In the "module-based passivation" operating mode (PAA byte 0, bit 1 = 0) the module passivation
is in accordance with the PROFIsafe specification.
–
In the "channel-based passivation" operating mode (PAA byte 0, bit 1 = 1) the affected channel
bits (Ex, Qx) are set to logic 0 in the input image (PAE bytes 0 and 1).
The module passivation is based on the PROFIsafe specification in the case of a diagnosed internal
module error.
The PROFIsafe timeout is the system reaction to a massive, stochastic failure of the module hardware.
2.3.2
Overview of applications
The input module can be used for the following tasks:
–
Connection of various switches and sensors within the safety chain
–
Use of multi-channel sensor applications with up to 8 secure inputs, can be grouped and configured
with the aid of 11 different function modes
–
Use as an input module for a higher-order safety controller. Multiple input modules can be used
together to monitor sensors independently of one another.
The following overview constitutes a selection and lists some but not all possible applications.
