F-DO configuration
Overview
The F-DO configuration interconnects up to 6 signals of the Safety Integrated Functions with the
failsafe digital output (F-DO).
Requirement
To output the status of a Safety Integrated Function over the F-DO, the Safety Integrated
Function must be enabled.
Description of function
The F-DO configuration interconnects multiple status signals with the failsafe output (F-DO).
ANDing the following signals produces the status of the F-DO:
• Status of the Safety Integrated Functions
• Safe State
The "Safe State" signal is the ORing of the statuses of multiple Safety Integrated Functions.
Parameters
The following list contains the parameters of the "Safe State and F-DO configuration" function.

Self-test of the fail-safe digital output
Overview
The self-test detects whether the fail-safe digital output can be switched into the safe state.
• F-DO 0+ switches to the Low state
• F-DO 0- switches to the High state
The converter responds with a fault if there is an unexpected feedback signal during the
self-test.
