Glossary
The task of a switch is thus to regenerate and distribute received signals. The switch "learns"
the Ethernet address(es) of a connected PROFINET device or additional switches and only
forwards those signals that are intended for the connected PROFINET device or switch.
A switch has a specific number of connections (ports). You connect at most one PROFINET
device or additional switch to each port.
Technology object
A technology object supports you in the configuration and commissioning of a technological
function.
The properties of real objects are represented by the technology objects in the controller. Real
objects can be, for example, controlled systems or drives.
The technology object includes all data of the real object that is required for its open-loop or
closed-loop control, and it signals the status information.
Temperature derating
The derating describes the maximum permissible heat dissipation of components depending
on the ambient temperature.
TIA Portal
Totally Integrated Automation Portal
The TIA Portal is the key to the full performance capability of Totally Integrated Automation.
The software optimizes all operating, machine and process sequences.
Total current
Sum of currents of all freely configurable channels.
Transmission rate
Speed during the data transfer and specifies the number of transferred bits per second (transfer
rate = bit rate).
TWIN wire end ferrule
Wire end ferrule for two cables
Value status
The value status is the binary additional information of a digital signal. The value status is
entered in the process image of the input and provides information on the validity of the signal.
