Phases of the V model:
Name Description
Design phase Validation phase
Specification and
validation of all
passive safety
measures and of all
active safety
measures. Specification of all applicable
safety measures, e. g. covers,
enclosures, max. machine
parameters, safety functions etc. Test of all passive safety measures
and of all active safety measures
for correct implementation and for
efficiency
Specification of the
functional safety
systems Specification of the active safety
systems an assignment of the
active safety systens to the risks
to be reduced, e. g. reduced
speed in set-up mode, stop
mode, monitoring of access
areas etc.
Specification of the PLr , or
rather, of the required SIL for
every particular safety function Test of all active safety systems for
efficiency and for observance of the
specified parameters, such as e. g.
correct speed, correct stop,
response of monitoring devices etc.
by means of practical tests.
Specification of the
software / specification
of the safety functions Specification of the functionality
of the particular safety functions
and definition of the
de-energizing circuit etc.
Definition of the parameters for
the particular safety functions
such as e. g. max. speed, stop
ramps, and stop categories etc. Prüfung der korrekten Umsetzung
der Funktionsvorgaben durch
Analyse FUP-Programmierung
Validation of the application
program and validation of the
paramters by comparison of the
validation report to the FUP, or
rather by comparison of the
validation report to the
requirements for the parameters
Specifiation of the
hardware Specification of the plant
structure and of the functions of
the different sensors, control
devices, control components ad
actuators with respect to their
safety functions Check of the correct
implementation of the specifications
Determination of the failure
probability, or rather, determiantion
of PL by means of analysis of the
total architecture and of the
identification data of all components
involved, always related to the
particular safety functions
Hardware design and
software design Concrete planning and
implementation of the plant
structure / of the wiring.
Concrete implementation of the
safety functions by programming
in FUP Nil
