Event Messages Related to Missing Field 
Device Data

Event messages that indicate missing field device data include: 

-

Technical problems in the field device 

-

Communication problems between the field device and the CDU 

The exact format of the event message depends on the configuration of the 
system. The typical event message contains sensor type and sensor 
location, for example,“WIND_SENSOR_SITE1_MISSING_DATA”. 

Check the communication lines to find out if the problem is in the field 
device or in the communication. 

NETWORK TIME PROTOCOL 
(NTP) SYNCHRONIZATION 
LOST

Connection to the NTP server of the local 
host cannot be established, or the NTP 
server has lost the connection to the primary 
clock, or has a too large deviation from the 
primary clock time.

SOLAR BATTERY (A/B): LOW 
VOLTAGE AT LLWAS SITE X

The solar battery voltage is low.

SOLAR BATTERY (A/B): 
VOLTAGE MEASUREMENT 
FAILURE AT LLWAS SITE X

The voltage from solar battery cannot be 
detected. Check the cables and refer to the 
solar battery and transmitter documentation.

TCP/IP SERVICE: Link NNNN 
failed to connect to remote host 
xxx.xxx.xxx.xxx, port yyyy. 
Reason: WSACONNREFUSED.

AviMet LLWAS TCP/IP Service failed to 
connect to remote computer. The network 
may be broken or the remote communication 
module may not be running. NNNN is the 
configured connection name, 
xxx.xxx.xxx.xxx is the IP address, and yyy 
the port number of the remote system. The 
message disappears when the connection 
succeeds.

UNABLE TO CONNECT TO 
SERVICE CONTROL 
MANAGER

The status of services cannot be examined, 
because the connection to the Windows 
component called Service control manager 
cannot be established. This alarm indicates 
either operating system level problems or 
error in system configuration. Contact 
Vaisala technical support.

WIND DATA MISSING

The system has received no data from wind 
sensor within specified time.
