Poznámky redaktora
An established term this context “Electromagnetic Compatibility (EMC)”.y Light signals As the complexity plants and systems steadily increases, so does the task collecting and distributing various types plant and process data. 22. However, the transmission rate heavily decreases the length the ire is increased. To reduce the effects electromagnetic influence as much possible, measures are also put place protect the devices and installations that could disturbed, with shielding one the most commonly used methods. Wherever electric current flows, electromagnetic fields are generated, but these fields must not allowed to influence even distort the inform ation that is transmitted usually the form digital data packets. Here, “safely and reliably” means more than just protecting the data against external access, as it also means ensuring data integrity physical level. The aim safely and reliably transmit the highest possible data volume the shortest time. For example, shielded copper wires can used data need to transm itted path that subject high electromagnetic influence. Wherever high current flows or high-frequency currents are present, high level of electromagnetic influence can expected. For this reason, the electromagnetic influence should reduced or ideally eliminated altogether the source the interference
