WLAN basic settings
The WLAN functionality can be configured via the following parameters.
Preconditions
WLAN module has been plugged onto the diagnostic module interface on the front of the inverter.
Details
–
The WLAN module can be connected and removed during operation.
–
The WLAN module can either create an own WLAN network (access point mode, default setting) or implement itself as a WLAN client in an already existing WLAN network. For details see the following subchapters.
–
The WLAN connection is encrypted. The WLAN encryption can be selected in 0x2441:009.
–
0x2441:012 can be used to set the name of the WLAN network, called SSID, so that it is not visible for other WLAN devices. As a result, the number of WLAN networks displayed on smartphone or PC can be reduced.
–
Two data sources are possible for the WLAN settings: Inverter and WLAN module.
–
Data source - inverter:
The WLAN settings saved in the inverter are used. Each inverter has its own WLAN settings.
The WLAN settings saved in the inverter are used. Each inverter has its own WLAN settings.
–
Data source - WLAN module: The WLAN settings saved in the WLAN module are used. In this "stand-alone" mode, the WLAN module can be plugged onto another inverter and then be used with the same settings (irrespective of the WLAN settings of the inverter).
–
The data source is activated with 0x2440.
–
The currently active data source is displayed in 0x2442:004.

–
From version 02.00
|
Definition of the start address when the Dynamic Host Configuration Protocol (DHCP) is used.
–
Only relevant for access point mode.
–
When 0 is set, the active IP address + 1 is used as start address.

WLAN settings: WLAN SSID
["i5"]
–
From version 02.00
|
Name (Service Set Identifier, SSID) of the WLAN network.
–
The preset name consists of the device name (iXXX) and the last 10 digits of the serial number of the Control Unit.
–
Example: "i550_0123456789"
–
The serial number is displayed in 0x2000:002 (P190.02).
|
|
|
0x2441:008
|
WLAN settings: WLAN password
["password"]
–
From version 02.00
|
Password (WLAN network key) of the WLAN network.
–
This password serves to secure the WLAN connections.
–
The password must have a minimum length of 8 characters. Although shorter passwords are accepted and saved, the WLAN module cannot be operated with such a password.
–
The character "*" is not allowed.
Note!
If the WLAN module is to be plugged onto the inverter for a longer period of time, it is important to select a safe password. Otherwise, a potential attacker might connect to the WLAN access point and attack the device and other connected devices or networks.
Currently (status: 2016), a WLAN is considered as safe if the password
–
consists of more than 20 characters,
–
contains capital and small letters, numbers and special characters and
–
cannot be found in any dictionary.
