Glossary

Bus
A common transfer route connecting all nodes and having two defined ends.
Configuration
Systematic arrangement of the individual I/O devices (configuration).
Connection plug
Physical connection between device and cable.
Derating
Derating allows devices to be used even in harsh operating conditions by selectively
restricting the output capacity. In the case of I/O devices, this usually refers to operation at
high ambient temperatures.
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.
Encoders
Encoders are used for the accurate detection of routes, positions, velocities, rotational
speeds, masses, etc. in the form of digital and analog signals.
EtherNet/IP
EtherNet/IP is a communication protocol based on TCP/IP and UDP/IP. EtherNet/IP thus extends
the use of all Ethernet components and the well-known network and transport protocols in
the industrial environment.
Firmware update
Upgrade of firmware for modules (interface modules, I/O modules etc.), e.g. after functional
enhancements, to the newest firmware version (update).
