The following points need to be taken into account when setting the cycle time. Otherwise it
may not be possible to establish stable communication.
● There is only one access point in the system; in other words, the clients move only in one
wireless cell. In this case, update times >= 16 ms are supported.
● There are several access points in the system that communicate over different channels.
The clients roam between the access points. In this case, select update times >= 32 ms.
In addition to the guide values shown above, remember that the shortest cycle time to be set
is calculated according to the formula "2 ms * max. number of nodes".
Requirement
The SCALANCE W700 device is in access point mode.
You are in the Interface Configuration mode of the WLAN interface.
The command prompt is as follows:
cli (config-if-wlan-0-X)#
Syntax
Call up the command with the following parameters:
wlan ipcf cycle-time <ms (4-512)>
The parameter has the following meaning
Parameter Description Range of values / note
ms Cycle time in millisec‐
onds (ms)
4, 8, 16, 32, 64, 128, 512
Result
The cycle time is configured.
Further notes
You display the setting with the show wlan ipcf command.
