Glossary
Cold restart
A start operation that is started by switching on the computer. On a cold restart, the system
typically performs a few basic hardware tests and then loads the operating system from the
hard disk into the RAM -> Booting.
Controller
Built-in hardware and software that controls the mode of operation of a certain internal or
peripheral device (e.g. keyboard controller).
Data point
Data points refer to elements (variables) via which values of data sources can be called (e.g.
MindSphere, powermanager, etc.). They are combined in a relevant aspect. For example,
"Temperature" and "Torque" are data points of the aspect "Energy_consumption". Data points
are configured in the "asset manager". In the "Fleet-Manager", their values are visualized as
time series.
Data source
A data source is a physical element of a device that can be monitored by MindSphere.
Example: 7KN Powercenter 3000.
Drivers
Parts of the operating system. They convert data of the user programs into specific formats
that are required by the I/O devices (e.g. hard disks, monitors, printers).
EMC Directive
EU directive governing electromagnetic compatibility. Conformity is confirmed with the
CE symbol and the EC certificate of conformity.
ESD guidelines
Guidelines for handling electrostatic sensitive devices.
Ethernet
Local area network (bus topology) for text and data communication at a data transmission
rate of 10/100/1000 Mbps.
Execute Disable Capability
Hardware implementation to prevent conflicting memory access by programs and
applications. It is only effective if it is supported by all the system components affected, such
as the processor, operating system, and application software.
