Troubleshooting Guide and FAQ
LonWorks Communication Module Only
The following section applies only to the
LonWorks
communication module.
The
LonWorks
communication module has a Service LED that
indicates the status of the module itself and the
LonWorks
network. This LED is useful for verifying communication
between the
LonWorks
communication module and the
network, and for diagnostic purposes.
provides
a description of the LED activity. Refer to the LonWorks
Communication Module Installation Manual,
, available
.
Table 18: LonWorks Communication Module - LED Activity
LED Activity
Description
LED flashes once when power has
been applied, or comes ON when
pressing the Service switch
Normal operation for a commissioned
LonWorks
communication module
LED is OFF continuously as soon as
power is applied
Faulty hardware or power supply
LED is ON continuously, even when
power is first applied
Faulty hardware or power supply
LED flashes when power is applied,
goes OFF, then comes ON solid
Indicates the communication module
does not have the application image
(APB/NXE) and interface (XIF) files
properly installed - reload application
files, which can be found on
LED flashes briefly once every second
The communication module could
be experiencing an error with the
application software or possibly
the hardware - reload application
files, which can be found on
LED steadily blinks ON and OFF at ½
Hz Rate (1 Sec = ON; 1 Sec = OFF)
Normal operation if the communication
module is decommissioned
Q:
Service Pin LED does not light when pressed
A:
The communication module may not be installed properly,
the hardware may be defective, or the LED itself may be
defective.
• Remove the communication module and then re-install it,
making sure the connector snaps into place on all four of
the pins. Use caution as it is easy to either miss just one
pin or all of the pins, even with the standoffs.
• Verify if the BAS recognizes the Neuron ID, even if the
LED is not lit.
• If the communication module is properly installed but
no Neuron ID is broadcast, remove the communication
module and install it on a different unit. If the LED does
not function correctly and/or the BAS still does not
recognize the Neuron ID, replace the communication
module.
Q:
The BAS does not “see” some or all
LonWorks
Configuration Properties
A:
The communication module uses multiple User-defined
Configuration Property Types (UCPTs) to pass Daikin-
specific unit information to the BAS. If the BAS can access
LonWorks network variables contained in the XIF file, then
it is likely that the BAS is not allowing access to these
user-defined configuration properties or has not properly
implemented the Resource Files giving access to the direct
memory read-write CPs.
• The controls integrator should contact his/her technical
support to determine how to allow the BAS to access
configuration properties.
• The complete set of
LonWorks files required for BAS
integration are available on
should it be necessary to reinstall
them.
Factory-installed
LonWorks
communication modules are
loaded with all application files required for network integration.
Segger Flasher5 Tools
The following section summarizes common issues with Flasher
tools and the corresponding solutions.
Q:
The main screen does not populate with the proper
Flasher information
A:
. This may indicate a problem with the
connection between Flasher and the computer
• Verify that the Flasher tool has power and that the
Flasher serial cable is connected to the computer.
• Additionally, check that the communications port selected
in the ‘Communications’ section of the ‘Options’ menu is
set to the correct port (i.e. the port to which the Flasher
tool is connected).
