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
