Device replacement without removable medium/programming device
IO Devices having this function can be replaced simply:
• A removable medium (such as Micro Memory Card) with the stored device name is not
required.
• The device name does not have to be assigned using the programming device.
The replaced IO Device receives the device name from the IO Controller, not from the
removable medium or from the programming device. For this purpose, the IO Controller uses
the configured topology and the neighborhood relationships determined by the IO Devices.
The configured setpoint topology must agree with the actual topology.
Diagnostics
Diagnostics is the detection, localization, classification, display and further evaluation of
errors, faults, and messages.
Diagnostics provides monitoring functions that run automatically while the system is in
operation. This increases the availability of systems by reducing setup times and downtimes.
Earth
The conductive earth whose electric potential can be set to zero at any point.
Electromagnetic compatibility (EMC)
Electromagnetic compatibility is understood as the ability of a piece of electrical equipment
to function perfectly in a specified environment without impacting on its surroundings in an
impermissible way.
Equipment, electrical
All components, power circuits or parts of power circuits that are normally to be found in one
single enclosure.
Equipotential bonding
Electrical connection (equipotential bonding conductor) that brings the conductive parts of
electrical equipment and other conductive parts to the same or approximately the same
potential in order to prevent troublesome or dangerous voltages arising between these parts.
EtherNet/IP adapter
The EtherNet/IP adapter corresponds to the PROFINET IO device.
EtherNet/IP scanner
The EtherNet/IP scanner corresponds to the PROFINET IO controller.
