EMC | Abbreviation for “Electromagnetic Compatibility”. The ability |
| of electrical equipment to function |
| particular environment without a negative effect on the |
| environment concerned. |
EN | Abbreviation for “European Norm” or European standard. |
Equipotential bonding | Adaptation of the electrical level of the body of electrical |
| equipment and auxiliary conductive bodies by means of an |
| electrical connection. |
ESD | Abbreviation for “Electrostatic Discharge”. |
Field supply | Voltage supply to field devices as well as signal voltage. |
Fieldbus | Data network on the sensor/actuator level. The fieldbus |
| interconnects the devices at field level. Characteristic feature |
| of the fieldbus is their highly reliable transfer of signals and |
| |
Galvanic coupling | A galvanic coupling occurs when two circuits use the same |
| cable. Typical sources of interference are, for example, |
| starting motors, static discharges, clocked devices, and a |
| potential difference between the housing of components and |
| the common power supply. |
GND | Abbreviation for “GROUND” (0 potential). |
Ground | In electrical engineering the name for conductive grounding |
| with an electrical potential at any point equal to zero. In the |
| environment of grounding devices, the electrical ground |
| potential may not equal zero. This is called a “reference |
| ground”. |
Ground (verb) | Represents the connection of an electrically conductive |
| component to the equipotential earth via a grounding device. |
Ground connection | One or several components that have a direct and good |
| contact with the ground. |
GSD | The device master data files (GSD) contain standardized |
| PROFIBUS station descriptions. They are used to simplify |
| the configuration of the DP master and DP slaves. |
Hexadecimal | Number system with base 16. Counting from 0 to 9 and then |
| with the letters A, B, C, D, E and F. |
