6.2.6 Configurator Error Indications and Remedies

If any of the following messages is displayed, the configurator is not normally functioning. Therefore, correct the

configuration file as appropriate and the execute the configurator again.

Error messages

cfg308 Error : syntax error near line xxx (xxxx.cfg)

There is an syntax error in the configuration file.

cfg308 Error : not enough memory

Memory is insufficient.

cfg308 Error : illegal option --> <x>

The configurator's command option is erroneous.

cfg308 Error : illegal argument --> <xx>

The configurator's startup format is erroneous.

cfg308 Error : can't write open <XXXX>

The XXXX file cannot be created. Check the directory attribute and the remaining disk capacity avail-

able.

cfg308 Error : can't open <XXXX>

The XXXX file cannot be accessed. Check the attributes of the XXXX file and whether it actually ex-

ists.

cfg308 Error : can't open version file

The MR308 version file "version" cannot be found in the directory indicated by the environment vari-

able "LIB308".

cfg308 Error : can't open default configuration file

The default configuration file cannot be accessed. "default.cfg" is needed in the current directory or

directory "LIB308" specifying.

cfg308 Error : can't open configuration file <xxxx.cfg>

The configuration file cannot be accessed. Check that the file name has been properly designated.

cfg308 Error : illegal XXXX --> <xx> near line xxx (xxxx.cfg)

The value or ID number in definition item XXXX is incorrect. Check the valid range of definition.

cfg308 Error : Unknown XXXX --> <xx> near line xx (xxxx.cfg)

The symbol definition in definition item XXXX is incorrect. Check the valid range of definition.

cfg308 Error : too big XXXX's ID number --> <xx> (xxxx.cfg)

A value is set to the ID number in XXXX definition that exceeds the total number of objects de-

fined.The ID number must be smaller than the total number of objects.

cfg308 Error : too big task[x]'s priority --> <xx> near line xxx (xxxx.cfg)

The initial priority in task definition of ID number x exceeds the priority in system definition.

cfg308 Error : too big IPL --> <xx> near line xxx (xxxx.cfg)

The system clock interrupt priority level for system clock definition item exceeds the value of IPL within
