3.2 Special product features
3 System description
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.
Two DCU1 (Distributed Control Unit) variants are also available with
integrated programmable logic. Details on DCU programming are available
in the µDCU Manual.
For connecting the network, power supplies, and E/A devices, the module
series features the widely used M12 connector with A-coding for the E/A
signals, D-coding for the network, and L-coding for the power supply. The
connectors are also color-coded to prevent the connections from being mixed
up.
3.2 Special product features
D
Robust design:
For connection capability, the module series offers the widely used M12
connector for the E/A signals, the network, and the power supply. 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.
D
Integrated switch:
The integrated two-port Ethernet switch of the modules allows a bus, star,
or ring topology for the EtherNet/IP network.
D
Redundancy function:
The LioN-P modules support the redundancy function DLR (device level
ring) for 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. The DLR class supported is “beacon-
based” according to the EtherNet/IP specification.
D
Failsafe function:
The modules with output functions (variants 16DIO, 16DO and 8DI/8DO)
provide a failsafe function. This allows you to define the behavior of
every single output channel in the case of an interruption or a loss of
communication.
