Introduction
What is EMC ?
Electromagnetic compatibility (EMC) is the ability of an electrical device to function, fault-free
in a specified electromagnetic environment without influencing the environment in an
inadmissible fashion.
This design and EMC Directive supplements the documentation on the individual
components.
The SIMATIC TDC control system consists of individual components (e.g. racks, modules,
interface modules, operator control panels, position transmitters). The components can be
installed in the widest range of system configurations to suit individual requirements. In an
environment that contains distributed components it is imperative not to neglect interference
and to conform with special installation and EMC requirements of the plant.
EMC therefore represents a quality feature for
●
Intrinsic immunity to interference: Resistance against internal electrical disturbance
variables
●
Immunity to external interference: Resistance of the system against external
electromagnetic disturbance variables
●
Degree of interference emission: Environmental effects caused by electromagnetic
radiation
Operational reliability and immunity to interference
The manufacturer of the control system and users (including end customers) must take
specific measures in order to achieve the maximum possible operational reliability and safety
and interference immunity for a complete system (control and drive system).
Proper functioning of SIMATIC TDC can only be ensured if all of these measures have been
observed in compliance with legal provisions (2004/108/EC).
