ACCON-NetLink-WLAN 3
1 TECHNICALDESCRIPTION
TheACCON-NetLink-WLAN isahigh-techcommunicationsand
programmingadapter betweenaPCandaS7controller.Thisconvincing
all-rounddevicecan beconnectedtothePLCviaMPI,PROFIBUS and
PPI.TheACCON-NetLink-WLAN detectsthecurrentbussettings,
independently. The connection cable oftheACCON-NetLink-WLANtothe
Bus(MPI,PROFIBUS orPPI)isan activeconnection,sothere are no bus
interferencesduetoaspurline.
Figure1:Build-up
TheACCON-NetLink-WLAN'scommunication tothePCiscarriedoutvia
TCP/IP.AlternativebyaccessingbyWLAN theACCON-NetLink-WLAN
hasalsoaRJ45 EthernetInterface.Theconfiguration oftheACCON-
NetLink-WLAN can becreatedandchangedviaitsintegratedwebsite.
Forsecurityreasonstheaccess tothewebsiteisprotectedbya
password.
TheACCON-NetLink-WLANsupportstheS7communicationviaRFC1006
(ISO on TCP). ThusTCP/IPcommunication processors(e.g.CP343-1)
can bereplacedbythisadapter.Butprojectedconnectionsare not
supported.Furthermore theACCON-NetLink-WLAN supportsthe
parametrization ofDP-SlavesviaDP-V1 (Class 2). Adriver forSIMATIC
applications(ACCON-S7-NET)isincludedindelivery. TheACCON-
NetLink-WLAN isfedviathebusconnection.Alternatively,thedevice
can beexternallysuppliedvia24 VDC.

ACCON-NetLink-WLAN 4
TheACCON-NetLink-WLAN can beconnectedtothePCviaahubor
switch.Thesuppliedpatchcable(straight)isusedtoconnectthe
ACCON-NetLink-WLAN viaaswitch.
Features:
• WLAN-Interface
• OptionalRJ45 Ethernet-Interface
• Automaticbusprofiledetection
• Full PROFIBUS speedupto12 MBit/s
• Extendeddiagnostics
• SupportofMPI,PROFIBUS andPPI
• SupportsDHCP
• SupportofSlaveprogrammingviaDP-V1 (Class 2)
• Supportsall establishedSIMATICEngineeringTools
• SupportsISO on TCP(RFC1006)
• Activeconnection cable,sothere are no businterferencesduetoa
