F-System Failsafe system
A failsafe system is a system that remains in the safe state or immediately enters a safe
state when specific failures occur.
i-Parameter Individual safety parameter of a device
Passivation If the safety module (F-I/O device) detects an error, it switches the affected channel or all
channels of the module to the safe state; the channels are then passivated. The detected
errors are reported to the safe controller.
For a safe input module when the F-System is passivated, instead of the process values
present at the safe inputs, substitute values (“0”) are provided for the safety program.
For a safe output module when the F-System is passivated, instead of the output values
provided by the safety program, substitute values (“0”) are transferred to the safe outputs.
PROFIsafe Safety-related bus profile based on PROFIBUS DP or PROFINET. It defines the
communication between a safety program and the safe I/O device (F-I/O device) in a safe
system (F-System).
PROFIsafe address Each safe module has a PROFIsafe address. This address must be set on the safety
module (F-I/O device) via DIP switches and then configured in the configuration tool for the
safe controller used.
PROFIsafe monitoring
time
Monitoring time for safety-related communication between the safe controller (F-CPU) and
safe I/O device (F-I/O device).
This time is parameterized in the F_WD_Time F-Parameter.
