3 System description
The LioN (Lumberg I/O network) -P and -R module series includes
standalone fieldbus devices for decentralized use in harsh industrial
environments. The devices feature easy handling of I/O data in a higher-level
bus system. They are especially suitable for use in machines and
installations with a moderate I/O concentration over separate assemblies.
The LioN-P/-R I/O module series has a very rugged metal housing of die-cast
zinc. The module electronics are fully protected from environmental
influences by the fully sealed housing. The modules feature degree of
protection IP67. The permissible temperature range of the modules is -10°C
to +60°C. The module series is therefore highly suitable for direct field use in
harsh industrial environments.
Despite the sturdy construction, the module series has compact dimensions
and a low weight.
The integrated 2-port Ethernet switch of the modules allows a bus or star
topology to be set up for the PROFINET I/O network. The implemented
Media Redundancy Protocol (MRP) enables the design of a highly available
network infrastructure.
The LioN-R module series consists of three types of modules with different
I/O functionality. Modules with 16 digital inputs (16 DI), 16 digital outputs (16
DO), and 8 digital inputs / 8 digital outputs (8DI / 8DO) are available. The
output current is 1.6 A per channel. The output power circuits are electrically
isolated from the rest of the network and the sensor electronics.
The modules with output functionality feature a failsafe function. During the
configuration of these modules, the behavior of each output channel can be
adjusted in case of interruption or loss of communication.
For connecting the network and the I/O devices, the module series features
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
connections from being mixed up.
In accordance with the PROFINET specification, the modules get their
network parameters from a DCP server. Rotary encoding switches are not
required.
