Automatic topology detection using LLDP
The Link Layer Discovery Protocol (LLDP - IEEE 802.1AB) is
a data link layer protocol which publishes information about
a device containing its IP address, description and functional
information to its neighbouring devices over the network. All
of Weidmüller’s managed switches fully support LLDP.
VLAN – simplies network planning
VLAN stands for virtual LAN. It is a network structure with all
the characteristics of a normal LAN, but not geographically
constrained. A network can be divided into different sections
using the VLAN function. It is possible, for example, to group
servers or workstations together, based on their function.
Data will only then be sent to Ethernet devices of a specic
VLAN group. The option for isolating VLANs completely from
one another serves to increase the security of data transfer
and offers additional protection from unauthorised access or
unauthorised data trafc.
Managed Switches introduction
Optimum integration and real-time communication
Weidmüller-managed switches support the automation
protocols PROFINET RT and Ethernet/IP. The devices can
thus be easily integrated into the respective engineering
tools (TIA-Portal, RSLogix) and parameterised and diagnosed
via the standard software environment. In addition, the
automation protocols support the prioritised transmission
of data, thereby enabling real-time communication between
the network participants.
