Closing the wireless network prevents unauthorized users from accessing
the Access Point RLM within a specified SIMATIC NET Industrial Wireless
LAN network. If a user tries to access the network, without configuring their
station with the correct network name, the station will not be able to bridge
data on the RLM.
There are two options for this type of access security: 2SHQ and &ORVHG .
• The
2SHQ
configuration is the standard IEEE 802.11 mode that will allow
access to the Access Point RLM for:
— all stations with the correct network name.
— all stations with the network name set to “ANY” .
• The
&ORVHG
configuration is the Siemens SIMATIC NET Industrial
Wireless LAN proprietary mode that closes your network to all stations
that have not been programmed with the correct network name.
This option will deny access to:
— all SIMATIC NET IWL stations with the network name set to “ANY”
and,
— all non-SIMATIC NET IWL stations with a “zero string SSID” or
“ANY” as network name.

The
&ORVHG
option is not compliant with the IEEE 802.11 standard
for wireless LANs.
