Glossary
C/Q
IO-Link communication signal / switching signal
Connection plug
Physical connection between device and cable.
Device
Device that can send, receive or amplify data via the bus, e.g. IO device via PROFINET IO.
Diagnostics
Monitoring functions for the detection, localization, classification, display, and further
evaluation of errors, faults, and alarms. They run automatically while the system is in
operation. This increases the availability of systems by reducing commissioning times and
downtimes.
Distributed I/O system
System with input and output modules that are configured on a distributed basis, far away
from the CPU controlling them.
Firmware update
Upgrading the firmware of IO-Link I/O modules, for example, after function extensions, to the
latest firmware version (update).
Ground
Conductive earth whose electrical potential can be set equal to zero at any point.
All interconnected, inactive parts of a piece of equipment that cannot accept any dangerous
contact voltage, even in the event of a fault.
