2.5 Risk assessment of the plant

Use in residential areas
Note
HMI device not intended for use in residential area
The HMI device is not intended for use in residential areas. Operation of an HMI device in
residential areas can have a negative influence on radio or TV reception.
2.5 Risk assessment of the plant
Note
Risk assessment in an F-system is always required
A risk assessment must be performed for each F-system. The responsibility lies with the
operator of the plant.
The following rules apply to the risk assessment of the plant:
● EN ISO 12100:2010, Safety of machinery – General principles for design of machinery –
Risk assessment and risk reduction
● ISO 13849-1, Safety of machinery - Safety-related parts of control systems - General
principles for design
The results of the risk assessment leads to the Performance Levels a to e in accordance
with ISO 13849-1, which indicates how the safety-related system components must be
designed if the stop or emergency stop functions are needed locally in a plant segment or
globally throughout the plant and which operating mode is to be used for the HMI devices in
a safety-related plant area.
Also refer to the technical specifications in the section "Mobile Panel (Page 233)", section
"Fail-safe operation". Take the plant configuration as a whole into consideration in the risk
assessment and not just the individual areas. Additional information on risk assessment and
risk reduction is available at:
