Radio Link Modules maintain dynamic lists to identify the interface
where they last spotted a SIMATIC NET IWL station (either the
Ethernet interface, or SIMATIC NET IWL interface A or B).
When the RLM receives a packet addressed to a specific station, this
list will help to determine to which interface the packet should be
bridged.
When mobile stations roam between multiple cells this table will be
updated automatically.
When there is no traffic from or to a specific station for a longer
period of time (for example when a station was shut down), the Filter
Aging Time determines how long the access point will 'remember'
the location of this SIMATIC NET IWL device.
Basic operating software for SIMATIC NET IWL PC Card and Radio
Link Module that is factory-installed.
Occasionally firmware upgrades may become available when new
functions or features are developed for your SIMATIC NET IWL
product.
