Emergency start
Emergency start deletes the thermal memory from SIMOCODE pro each time it is activated.
This allows the motor to be immediately restarted after an overload trip. This function can be
used to:
● Enable an immediate restart/reset after an overload trip
● Influence the thermal memory (motor model) during operation, if required.
Since the emergency start is edge-triggered, this function cannot permanently affect the
thermal motor model.
EMERGENCY STOP
Shutdown in case of an 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 command device
Contact block ("EMERGENCY STOP" mushroom pushbutton according to
EN EN 418 (ISO 13850), cable-operated switch with positive opening contacts according to
EN 60204-1) that causes the process, machine or plant to be stopped when actuated in
hazardous situations. This must have positive-opening contacts, be easy to reach and be
tamper-proof.
EMERGENCY STOP device
Protective device that is operated in response to an emergency according to
EN 418 (ISO 13850), EN 60204-1.
Enabling circuit
An enabling circuit is used to generate a safety-related output signal. From an external
viewpoint, enabling circuits act as NO contacts (however, in terms of functionality, safety-
related opening is always the most important aspect). A single enabling circuit, that is
internally redundantly configured in the safety relay (two-channel) can be used for Category
3/4 according to EN 954-1 (ISO 13849-1).
EtherNet/IP
EtherNet/IP (EtherNet Industrial Protocol, often simply called EIP) is a real-time Ethernet that
is used mainly in automation engineering. EtherNet/IP was developed by Allen-Bradley
(belongs to Rockwell Automation) and was later handed over to the Open DeviceNet Vendor
Association (ODVA) as an open standard. In 1998, a working group of ControlNet
International designed a process for basing the already-published application protocol,
Common Industrial Protocol, on Ethernet. Based on this process, EtherNet/IP was published
as an open industrial standard in March 2000. ControlNet International (CI), the Open
DeviceNet Vendor Association (ODVA) and the Industrial Ethernet Association (IEA) were
involved.
Besides PROFINET and Modbus/TCP, EtherNet/IP is an Ethernet-based fieldbus that is
currently widely spread.
