Importance of operating instructions
The operating instructions are an integral part of the DIORAIL module product and must be kept ready
to hand at all times. This applies until the module is disposed of. If the module is sold or lent out, the
operating instructions must be passed on with it.
Copyright
These operating instructions are only intended for the operator and its staff. The contents of these
instructions may not be forwarded, reproduced, used or otherwise imparted, either in full or in part,
without express permission.
Infringements may result in criminal convictions.
Disclaimer
We have checked the contents of this document for conformity with the hardware and software
described. Nevertheless, as discrepancies cannot be ruled out we do not accept liability for complete
conformity. The information in this document is checked regularly and any necessary corrections are
made in the subsequent editions. We are grateful for any suggestions for improvements.
Friedrich Lütze GmbH & Co. excludes all liability for damage caused by a lack of or insufficient
familiarity with the operating instructions. The operator is therefore advised to get written confirmation
that staff are fully versant with the instructions.
Modifications or functional changes to the Ethernet/IP bus interface for DIOLINE20 are not permitted
for safety reasons. Modifications to the Ethernet/IP bus interface for DIOLINE20 not expressly
approved by the manufacturer will thus forfeit any liability claims against Friedrich Lütze GmbH & Co.

Qualifications of staff
Only qualified staff may perform the following work on DIORAIL modules:
Installation
Commissioning
Operation
Maintenance
Qualified staff in the context of the safety instructions are people who are authorised to commission,
earth and label devices, systems and circuits in accordance with the standards for safety engineering.
The operating staff must be briefed and trained accordingly.
Maintenance of the Ethernet/IP bus interface for DIOLINE20
The Ethernet/IP bus interface for DIOLINE20 itself is maintenance-free. No inspection or maintenance
intervals are therefore required for ongoing operation.
Decommissioning and disposal of the Ethernet/IP bus interface for DIOLINE20

avoid damage to property. These instructions are indicated by a warning triangle and graded
according to the degree of hazard.
Immediate hazard
to the life and health of people.
Failure to observe these will result in death or extremely serious injuries
(crippling).
Potential hazard
to the life and health of people.
Failure to prevent it may result in death or extremely serious injuries.
Potentially dangerous situation
Minor injuries may result if it is not averted.
This symbol is also used as a warning against damage to property.
Instructions for correct handling
Designate a situation that could potentially result in damage.
Failure to observe these instructions may cause damage to the product or

Further safety instructions
The Ethernet/IP bus interface for DIOLINE20 corresponds to the current state of the art and complies
with the applicable safety regulations and the relevant harmonised
European standards (EN).
Users must observe:
Pertinent accident prevention regulations
EC directives or other country-specific regulations
Generally recognised safety regulations
General ESD regulations.
The modules must be disconnected from the power supply when carrying out installation or
maintenance work (disconnect the mains plug). This can prevent accidents caused by electrical
voltages.
If electrical welding work is carried out on frames on which electrical modules
are mounted, all connections to and from these modules must first be
disconnected. This is the only way to protect the modules from being
destroyed by equalising currents.
Faults of any kind or any other kind of damage must be reported to a responsible person.
Protective and safety devices must not be bypassed or bridged. Dismantled safety devices must be
reassembled before commissioning again and must be subjected to a function test.
The modules must be secured against inappropriate or accidental use.
Original information signs, labels, stickers or similar must always be heeded and kept in a legible
state.
A DC 24 V power pack is used to supply power to the Ethernet/IP bus interface for DIOLINE20.
The operating voltage of DC 24 V is categorised as SELV (safety extra low voltage) and is thus not
subject to the EC Low Voltage Directive. Usage of other power supplies is not allowed.
The power is fed to the Ethernet/IP bus interface for DIOLINE20 at X3. The logics supply for the
expansion modules is fed on via the L-Bus ribbon cable from interface to interface.

2 Product overview of DIOLINE20
The Ethernet/IP bus interface is a connector between the Ethernet and the DIOLINE20 interface
modules.
The DIOLINE20 modules have been designed for use in rail vehicles.
A module network consists of the standardised controller core as the head of each network and a
maximum of 10 additional expansion modules from the DIOLINE20 family. The expansions are
connected by a flat conductor from interface to interface.
A loose connector without flat conductor is enclosed with the Ethernet/IP head. This is intended to
protect the contacts of the expansion slot in the last module of the network.
The DIOLINE20 product family is comprised of a multitude of combinable
interface types.
There are both digital and analogue input and output modules.
The description of the interfaces is enclosed with the respective modules.

4.3 Functional description
4.3.1 Introduction
The module is used as a bus connector between the realtime Ethernet network "Ethernet/IP" (see [1])
and the Lütze field bus, referred to here as "L-Bus". The physical I/O functionality is provided by the
DIOLINE20 modules connected to the L-Bus.
The digital and analogue process data read via the Ethernet/IP or L-Bus are thereby transferred
completely and consistently on the L-Bus or Ethernet/IP.
The L-Bus is transparent to the Ethernet/IP network, i.e. the module acts, with regard to the I/O
technical data sets, as a highly flexible I/O module that can be individually configured within a wide
range.

Ethernet/IP bus interface for DIOLINE20 Vers. 1.00 Functional description
20/45
4.3.2 L-Bus
The L-Bus is a proprietary field bus from Lütze and is used to connect the single I/O submodules
(DIOLINE20 modules).
All process data and status information from this bus are consistently mapped asynchronously on the
Ethernet/IP; therefore, from the perspective of the other Ethernet/IP users, the L-Bus is transparent.
4.3.3 Ethernet/IP
Ethernet/IP is a realtime Ethernet network protocol based on standard TCP/IP and implemented by
the Common Industrial Protocol (CIP) of the (common) application layer.
The modules functions as an Ethernet/IP adapter of "communication adapter" subscriber class (see
[1]) and therefore supports the following features:
Communicates messages (explicit communication of Transport Class 3)
Communicates messages in realtime (process data) (implicit (multicast) communication of
Transport Class 1)
Supports both input-only and output-only connections
Supports configuration assembly
Supports Electronic Key Management
Supports Repeated Packet Interval (RPI) >= 20 ms
Supports Quality of Service (QoS) for implicit messages
Supports star and line shaped network topologies
