IT Security
Kendrion Kuhnke products are designed for use in closed (private) industrial network environments.
In case such industrial networks are open to public access (e.g. via fully accessible network interfaces) or
otherwise externally accessible (e.g. via data links and public (Internet) traffic), the integrator and operator
must take appropriate organisational and technical precautions to protect the in-house network and ensure
IT security.
Information
To find information about how to safely operate equipment, systems and networks, please refer
to the texts published by BSI (Federal Office for Information Security), other publicly available
sources and IEC 62443.
Electromagnetic Compatibility
Definition
Electromagnetic compatibility is the ability of a device to function satisfactorily in its electromagnetic
environment without itself causing any electromagnetic interference that would be intolerable to other
devices in this environment.
Of all known phenomena of electromagnetic noise, only a certain range occurs at the location of a given
device. It is defined in the relevant product standards.
The design and immunity to interference of programmable logic controllers are internationally governed by
standard
IEC 61131-2 which, in Europe, has been the basis for European Standard
EN 61131-2.
Information
Refer to IEC 61131-4, User's Guideline, for general installation instructions to be complied with
to ensure that hardware interface factors and the ensuing noise voltages are limited to tolerable
levels.
Interference Emission
Interfering emission of electromagnetic fields, HF
compliant to EN 55011, limiting value class A, Group 1
Information
If the controller is designed for use in residential areas, high-frequency emissions must comply
with limiting value class B as described in EN 55011.
Fitting the controller into earthed metal cabinets and installing filters in the supply lines and other
means may produce a shielding compliant to the above standard.
General Notes on Installation
As component parts of machines, facilities and systems, electronic control systems must comply with valid
rules and regulations, depending on their field of application.
General requirements concerning the electrical equipment of machines and aiming at the safety of these
machines are contained in Part 1 of European Standard EN 60204 (same as VDE 0113).
Electrical Immission Safeguard
To eliminate electromagnetic interference, connect the control system to the protective earth conductor.
Practice best cable routing.
