Problem
Possible cause
Action
WLAN data communication between controller and tool
No WLAN
communication
between controller and
tool.
IP address of tool is not
entered correctly on the
controller.
¾
Check in the
Communication/Tool
screen of
the controller that the IP address of the tool is
entered in the
RF Tool IP
field. The IP address
of the tool is displayed on the tool in the
WLAN
RF settings
submenu.
Note:
If the settings are changed, it is necessary
to press
Accept
<F1> in order to apply the set-
tings.
Tool is not configured
with correct WLAN
parameter values.
¾
Configure the WLAN settings of the tool in the
Communication/Tool
screen of the controller
via infrared communication.
WLAN network set-
tings of the controller
and the access point
differ.
¾
In the
Communication/Tool
screen of the con-
troller, check that the settings of the access
point match the wireless network settings (Net-
work name, Security, Network key).
MAC address filter of
the access point is
active.
¾
Add the MAC address of the tool to the
address list of the access point. The MAC
address of the tool is displayed on the corre-
sponding label above the battery, and in the
WLAN RF settings
submenu.
A firewall blocks port
4001.
¾
Reconfigure the firewall so that the specific IP/
MAC address of the tool can use port 4001.
The RF channel at the
access point is out of
the tool-supported
range.
¾
Change the channel setting of the access point
to a channel between 1 and 11.
Tool is already
assigned to a different
controller.
¾
Check whether any other controller has
already established a connection to this tool.
That means another controller use same IP
address.
WLAN communication
partly interrupted.
Distance between
access point and tool is
too great.
¾
Check the signal strength in the
WLAN RF set-
tings
submenu of the tool. For stable communi-
cation, the first value (N) should be greater
than 15. If the value is less than 15, move the
access point closer to the tool.
Tool is also assigned to
a different controller.
¾
Check whether this tool (IP address) is
assigned to any other controller. If so, delete
the assignment on the other controller. A tool
can only be assigned to one controller.
Too much traffic on the
wireless network.
¾
Reduce traffic on the wireless network.
Deactivate torque plot data transmission.
