About the LioN Link module series
LioN (Lumberg I/O Network) Link is a modular system for decentralized use
in a rough industrial environment for easy handling of the I/O data in a
superordinate EtherNet/IP network. The system is particularly useful for
locations of use with high I/O concentrations in distributed assemblies.
The LioN Link system comprises of a BusHead and various field bus-
independent I/O modules. The maximum extent of the link systems is 100 m
per link connection. In other words, the maximum extent is 200 m for
2 connections.
The very compact dimensions and the low weight of the modules make
deployment in cramped conditions on robot devices possible. LioN Link's
degree protection class is IP 67.
The LioN Link BusHead 940 ESL 611 EIP supports the EtherNet/IP protocol
and connects the I/O modules from the LioN Link system with the control
system. The integrated 2-port switch additionally supports bus topology in
addition to the previously typical star topology. In addition to this, the modules
support the DLR (Device Level Ring) redundancy function in ring topologies.
With this function, if the connection is interrupted, the modules immediately
switch to an alternative ring segment and thus ensure interruption-free
operation. Monitoring of the physical connection is bacon-based, as per the
EtherNet/IP specification.
Each line can be extended to included up to 15 I/O modules. The distances
between 2 Link nodes is arbitrary. The permissible total length per strand
must not be exceeded. When using the maximum expansion, an additional
feed of system/sensor supply voltage is possible via T-pieces and/or on the
last LioN Link node.
