Glossary
Bus system
All nodes physically connected to a bus cable form a bus system.
Cycle time
The cycle time of a PROFIBUS segment is made up of the number of nodes. It is set, for
example, in TIA in the HW Config.
Cyclic execution
The DP master accesses the DP slaves regularly. In doing so, the DP master reads the input
data of the slaves and forwards output data to the slaves.
Diagnostics
The detection, localization, visualization and further evaluation of errors, disturbances and
messages.
Diagnostics offers monitoring functions that automatically run while the system is in
operation. This reduces startup times and standstill times. Plant availability increases.
Equipotential bonding
Electrical connection (equipotential bonding conductor) that keeps the conductive parts of
electronic equipment and extraneous conductive parts at an equal or approximately equal
potential. This prevents disruptive or dangerous voltages between these parts.
Master
When a master is in possession of the token, it can send data to other nodes and request data
from other nodes.
Nodes
Device which can send, receive or amplify data on the bus, e.g., PROFIBUS DP master,
PROFIBUS DP slave.
PROFINET IO controller
A PROFINET IO controller is the station in an automation system in which the control
programs runs. It handles process data traffic with the PROFINET IO devices.
