2.5 Risk analysis of the plant

Use in industry

The HMI device is designed for industrial use. For this reason, the following standards are

met:

● Interference emission requirements, paragraph 7.3, DIN EN 60947-1, Environment A

● Interference immunity requirements DIN EN 61326

Residential use

NOTICE

Interference to radio and TV reception

The HMI device is not suitable for use in residential areas: Operation of HMI devices in

residential areas can cause interference to radio and television reception.

If the HMI device is used in a residential area, you must take measures to achieve Limit

Class B conforming to EN 55016 for RF interference.

To achieve radio interference suppression class B, for example, install filters in power supply

lines.

Individual acceptance is required.

Risk analysis of the plant

The following rules apply to the risk analysis of the plant:

● ISO 12100-1 and ISO 12100-2, General design guidelines for machines

● ISO 13849-1, Safety of machinery - Safety-related parts of control systems - General

principles for design

● ISO 14121-1, Safety of machinery – Risk assessment – Part 1: Principles

These considerations result in a performance levels a to e in accordance with ISO 13849-1,

which dictate how the safety-related parts of the system must be furnished.

The safety-related parts of the HMI device meet:

● SIL 3 in accordance with IEC 61508

● Performance level e and Category 4 in accordance with ISO 13849-1

Take the plant configuration as a whole into consideration in the risk analysis and not just the

separate sections. For additional information on risk analysis and risk mitigation, refer to the

"Safety Technology in SIMATIC S7" system manual
