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.
iParameter
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 indicated at 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.
