B
Bus node: The bus node provides the connection to specific field buses. It transmits control signals to the
connected modules and monitors their ability to function.
C
CANopen: CAN-based fieldbus protocol standardised as a European standard.
CODESYS V3 pbF: CODESYS V3 provided by Festo allows the configuration, commissioning and
programming of different Festo components and devices. Abbreviation used sometimes in this document:
CODESYS.
CODESYS target system ID  Target system ID.
D
DHCP: Dynamic Host Configuration Protocol; dynamic protocol for automatic assignment of IP addresses.
E
I/Os: Digital inputs and outputs.
EasyIP: UDP-based protocol for rapid exchange of operands between controllers.
EDS file: Electronic data sheet; this file describes the functions and features of a CANopen device in
standardised form (e.g. number of I/Os, number of diagnostic bytes).
Ethernet: Physical protocol and network for connecting various devices.
F
Function block: In this document, "function block" is used as a general term for function module, function
and program.
FFT: Festo Field Device Tool.
I
IO-Link: Point-to-point connection for sensors and actuators. It can be used to automatically parameterise
IO-Link devices (e.g. sensors), diagnose system states and transfer measured values.
IODD: File for configuring IO-Link devices.
M
Modbus TCP: Communication standard via TCP/IP (port 502) in automation technology.
N
Node ID: Serves to clearly identify a bus slave on the CANopen fieldbus.
User data: Telegram data without protocol frame data. The length of the user data is defined in the
configuration of the field bus slave.
O
OLE: Object Linking and Embedding.
OPC: OLE for Process Control; standardised software interface that provides access to process data.
