errors, activates for example a reset of the outputs - or alternatively holds
the last state
I-port I-port is a Festo-specific interface for transmitting communication data
(process data, sensor signals, pilot signals) and supply voltages. The
I-port communication protocol is based on the IO link protocol. The elec-

1.1.2 I-port interface
I-port is a Festo-specific interface for transmitting communic-
ation data (process data, sensor signals, pilot signals) and
supply voltages.
The I-port communication protocol is based on the IO link
protocol. The electrical and mechanical link between bus
nodes and I-port device is standardised.
The bus node has separate operating and load voltage sup-
plies. It also supplies voltage to the devices connected via the
I-port interface.
Located at the bottom of the bus node is the I-port interface
for connection to an I-port-compatible device, e.g. valve ter-
minal or decentralised electrical connection box.

1.1.3 CTEU-DN function range on the DeviceNet (brief overview)
– Object-based fieldbus system
– Master-Slave system architecture
– Process synchronisation in accordance with the Producer/
Consumer method
– Connection-based communication procedure: point-to-
point connection (peer-to-peer messaging), where applic-
able as Multicast connection and/or Master/slave I/O
connection
– Predefined master/slave connection set for the simplified
transmission of I/O data between the master and the PLC
and the slave and the bus node
– Real-time operation: Exchange of I/O data in “real-time”
– Message types supported for the Master/slave I/O con-
nection:
– Polled communication (“I/O polling”)
– Change of state / Cyclic communication
– Supports the QuickConnect feature and the Automatic
Device Replacement (ADR) function: guarantees faster
reconnection between DeviceNet-Scanner and bus nodes,
e.g. after replacing the bus nodes
– Application-specific process data transmission based on
the Common Industrial Protocol (CIP):
– Time-critical I/O data via “I/O messages”
(I/O messaging or implicit messaging)
– Data required for configuration, diagnostics and
management via explicit messaging
– Module-specific parameterisation via manufacturer-spe-
cific objects

1.2 General information on the fieldbus protocol DeviceNet
1.2.1 Central component of the fieldbus protocol
Participant features
A DeviceNet participant is configured based on product-spe-
cific data and characteristics, which the manufacturer
provides in the form of electronic datasheets (EDS). These
EDS files contain the product code, revision data and the
available address space (input/output size).
The configuration program of the DeviceNet Master manages
the EDS files of all fieldbus participants in a list or an EDS
library.
Special Device Configuration Files contain additional project
data over and above the content and scope of the EDS file.
Communication protocol
According to the layer model of the International Organisation
for Standardisation (Open Systems Interconnection Reference
Model - OSI), DeviceNet uses the principles of the Controller
Area Network (CAN) Protocol at security layer level (Data Link
Layer),aswellastheCommonIndustrialProtocol(CIP)forthe
upper communication level.
The DeviceNet protocol therefore represents a conversion
from CIP based on CAN principles.
