Glossary

Automation system
Programmable logic controller for the closed-loop and open-loop control of process chains in
the process engineering industry and manufacturing technology. The automation system
consists of different components and integrated system functions according to the
automation task.
Baud rate
Data transmission rate indicates the number of bits transmitted per second
(baud rate = bit rate).
Bus
A common transfer route to which all nodes of a field bus system are connected; it has two
defined ends.
Bus cable connector
Physical connection between the bus node and the bus cable.
Configuration
Systematic arrangement of the individual modules (configuration).
Crimping
Procedure whereby two components that are joined together, e.g. end sleeve and cable are
connected by means of plastic forming.
Device names
Before an IO device can be addressed by an IO controller, it must have a device name. This
approach was chosen for PROFINET because names are easier to administer than complex
IP addresses.
An IO device has no device name upon delivery. An IO device can only be addressed by an
IO controller - e.g., for transferring configuration data (including the IP address) during
startup, or for user data exchange during cyclic operation - after it has been assigned a
device name with the programming device/PC.
