Glossary
DIP switch
Small switch used to make certain basic settings. The abbreviation stands for Dual In-line
Package, in other words a device package with two parallel rows of electrical connecting
pins.
Distributed
In a distributed automation network, individual components are interconnected multiple
times. This type of network ensures stable data transmission. Communication is still possible
even if one or more connections are faulty.
DM-F Local and DM-F PROFIsafe digital modules
The DM-F Local and DM-F PROFIsafe fail-safe digital modules are used as safety relays in
emergency stop devices in accordance with EN 418 as well as in safety circuits in
accordance with EN 60204 (11.98):
DM-F Local digital module: For applications that require local safety-related tripping with
EMERGENCY OFF buttons.
DM-F PROFIsafe digital module: For applications that require decentralized safety-related
tripping with EMERGENCY OFF buttons. A fail-safe SIMATIC controller adopts the logical
connection between the EMERGENCY OFF button and the PROFIsafe fail-safe digital
module (DM-F PROFIsafe).
Electromagnetic Compatibility (EMC)
In electrical engineering, EMC (electromagnetic compatibility) describes the mutual
interference that occurs between electrical devices which produce electromagnetic
interference fields.
Emergency stop
Shutdown in case of emergency according to EN 418 (ISO 13850). An action in an
emergency that is intended to stop a process or motion that would result in a hazard.
Emergency stop control device
Switching element ("emergency stop" mushroom pushbutton according to
EN EN 418 (ISO 13850) or cable-operated switch (positive opening) according to
EN 60204-1) that is operated in dangerous situations and stops the process, machine, or
system. This element must have positive-opening contacts, and it should be easily
accessible and tamper-proof so that it cannot be manipulated.
Emergency stop device
Protective device that is operated in response to an emergency according to
EN 418 (ISO 13850), EN 60204-1.
