TLVs Discarded
Each LLDP frame can contain multiple pieces of information, known as
TLVs (Type Length Value). If a TLV is malformed, it will be counted and
discarded.

If an LLDP frame is received with an organizationally TLV but the TLV is
not supported, the TLV is counted and discarded.
Age-Outs
Each LLDP frame contains information about how long the LLDP

within the age-out time, the LLDP information is removed and the value
of the age-out counter is incremented.

3.3.8 Industrial Protocols
In this page the user can activate the industrial protocols supported by the switch: Modbus TCP,
Ethernet/IP and Profinet.
3.3.8.1 Modbus TCP
Introduction
MODBUS TCP is a protocol commonly used for the integration of a SCADA system. It is also a
vendor-neutral communication protocol used to monitor and control industrial automation equipment
such as PLCs, sensors, and meters. In order to be fully integrated into industrial systems,
Weidmüller’s switches support Modbus TCP/IP protocol for real-time monitoring in a SCADA system.
