1.3 Terminology used
Term Meaning
CL-RPC Connectionless Remote Procedure Call
Code Parameter for parameterising or monitoring the field device. The term is also
referred to as "index" in common usage.
Controller The controller is the central component of the automation system which
controls the Logic and Motion functionalities (by means of the runtime
software).
The controller communicates with the field devices via the fieldbus.
Engineering PC The Engineering PC and the Engineering tools installed serve to configure and
parameterise the system.
The Engineering PC communicates with the controller via Ethernet.

EtherCAT® (Ethernet for Controller and Automation Technology) is an Ethernet-
based fieldbus system which fulfils the application profile for industrial real-
time systems.
EtherCAT® is a registered trademark and patented technology, licensed by
Beckhoff Automation GmbH, Germany.
Fieldbus stations Controller (PLC) and inverter integrated into the bus system (PROFINET)
Field device
GSDML file
A GSDML file described the properties of a field device.
It is described with the XML-based language GSDML (General Station
Description Markup Language).
I/O device PROFINET slave
I/O master PROFINET master
The I/O master takes over the master function for data communication of the
decentralised field devices. The I/O master is usually the communication
interface of a PLC.
Inverter Generic term for Lenze frequency inverters, Servo Inverters
PDO Process Data Object
PLC Programmable Logic Controller
(German designation: SPS - Speicherprogrammierbare Steuerung)
PROFINET® (Process Field Network) is a real-time capable fieldbus system based
on Ethernet.
PROFINET® is a registered trademark and patented technology licensed by the
PROFIBUS & PROFINET International (PI) user organisation.
RT over UDP Real Time over User Datagram Protocol
Subcode If a code contains several parameters, they are stored in so-called "subcodes".
This manual uses a slash "/" as a separator between code and subcode
(e.g. "C00118/3").
In normal usage, the term is also referred to as "Subindex".
