8-2 Common Command Line Errors (UCL)
UCL# Description
1 service is locked [UCL#1]
The UCL engine is locked. The UCL engine LONUCL32 cannot
reference itself. Make sure to specify the correct target UCL service
other than LONUCL32; contact LonSupport if the problem persists.
2 service not found. [UCL#2]
The targeted UCL service cannot be found. Make sure the service
DLL is in a folder contained within the current user's search path,
and make sure the DLL exists.
3 target service locked. [UCL#3]
The target UCL service is already in use, and does not support
multiple concurrent clients. Wait for the first client to detach, and
attempt to re-attach thereafter.
4 target service fails to initialize [UCL#4]
The target service cannot be initialized correctly. Such failure could
be caused by a required but missing DLL, or some other service-
dependent initialization failure.
5 invalid command, or malformed parameter [UCL#5]
Invalid option. An unknown command was sent to the target UCL
service. Check the service documentation for supported commands
and options.
6 invalid value [UCL#6]
An invalid parameter value was provided. Check the service
documentation for supported commands and their parameters.
7 the requested feature is not available [UCL#7]
The targeted service does not support the feature required to fulfill
the request. For example, the targeted service might not provide
help strings for on-screen usage hints, or it might not support
parameters with a particular data type. Contact LonSupport if
problem persists.
8 service not initialized. [UCL#8]
An attempt has been made to use an uninitialized UCL service. This
is an internal error condition, contact LonSupport.
9 wrong context. [UCL#9]
A UCL server operation has been requested out of context. This is
an internal error condition, contact LonSupport.
10 Command not understood: <cmd> [UCL#10]
Failure in command parser – see error message for details.
Commands on the command line or in a command file cannot be
understood due to a syntax error. See on-screen usage hints or
printed documentation for a listing of supported command line
parameters.
