3.1 About the LioN-P/-R module series
LioN modules (Lumberg input/output Network) function as the interface in an
industrial fieldbus system: They enable a central controller on the
management level to communicate with the decentralized sensors and
actuators on the field level. The line or ring topologies that they can be used
to create not only ensure reliable data communication but also significantly
reduce the cables required and thus also the costs for installation and
maintenance. They additionally enable easy, quick extension.
The modules of the LioN-P/-R series have a very sturdy metal housing made
of die-cast zinc. The completely cast device housing protects the module
electronics from environmental effects and allows the device to be used in a
wide temperature range. Despite the sturdy construction, the modules have
compact dimensions and a low weight. They are especially suitable for use
in machines and installations with a moderate I/O concentration over
separate assemblies.
3.2 Special product features
 Robust design:
The connection option provided by the module series is the widely-used
M12 connector with A coding for the I/O signals and D coding for the
network. The connectors are also color-coded to prevent the ports from
being mixed up. The output power circuits are electrically isolated from
the rest of the network and the sensor electronics. This reliably protects
the control devices from interference signals.
 Integrated switch:
The integrated 2-port Ethernet switch of the modules allows a bus or ring
topology to be set up for the EtherNet/IP network. The additionally
implemented DLR protocol enables you to design a high-availability
network infrastructure.
