7.2.2 Engineering
Objective In order to achieve functional safety of a machine or system, the safety-relevant
parts of the protection and control equipment must function correctly and
respond in such a way that if a fault occurs the system remains in a safe state
or is brought into a safe state. This demands the use of specifically qualified
technology that meets the requirements described in the relevant standards.
"SINUMERIK Safety Integrated" is one aspect of this qualified technology
(certified, e.g. to EN 954-1) and must be integrated in the machine in such a
way that functional safety is achieved in conjunction with the other protective
equipment of the machine/system (e.g. protective doors, EMERGENCY STOP
buttons, ...).
The aim of this configuration is to describe the machine-specific combination of
"SINUMERIK Safety Integrated
Sequence When engineering the SI system, the machine functions are sub-divided into
different operating modes (these operating modes are initially independent of
the NC operating mode – the relevant combinations must be configured). The
safety functions that are to be activated when the protective doors are opened
and closed are then defined.
The two operating modes – setting-up and production - are used in the machine
example. For an EMERGENCY STOP, the drives of the complete drive group
are brought to a standstill via external stops (Stop C -> Stop A).
Assigning the The required safety functions are defined for the machine operating modes.
operating modes
The machine operating mode (setting-up/production) is selected using a key-
operated switch. Production is the default machine operating mode. Usually,
the key-operated switch can only be actuated by authorized personnel. This
means that only appropriately trained personnel can move the machine when
the protective door is open.
