Debug methods
This section describes debug methods when the script is executed.
Operation check procedure
1
Send the FmtSet.lua file to SR-1000/D100/750/700 Series using
AutoID Network Navigator.
2
Start the AutoID Network Navigator [Terminal] and click [LON] to
start reading.
3
Read with the code reader and check if the result is correctly
reflected.
• For editing read data
→ Check if the output data is correct.
• For editing image file name
→ When using the setting to send image files via FTP, check the name of
image file uploaded on the specified FTP server.
* While reading, if an error message such as "Load Error" is displayed, debug
according to the following debug methods.
*1 The time for script timeout should be 3 seconds.
Debug methods
„ Error details check
1
Send the "SCPERR" command to SR-1000/D100/750/700 Series with
AutoID Network Navigator [Terminal]. (Executing this command will
display the error details.)
2
"error ~~~ FmtSet.lua: ○ : ~~" is displayed. The number applied to ○
is the corresponding row in error.
Open FmtSet.lua with the text editor and repair the source code.
„ print(mes) display (Page 12)
To check (debug output) the variable value in the source code of FmtSet.lua,
use the print function.
1
Write the print function on where the variable value is to be checked
in the source code of FmtSet.lua.
2
Send the "SCPDBG,1" command to SR-1000/D100/750/700 Series
with AutoID Network Navigator [Terminal]. (Executing this command
enables debug output when reading.)
3
Click [LON] to start reading.
The content specified as the argument of the print function is output.
Referring to this output result, open FmtSet.lua with the text editor and repair
the source code.
4
After the source code is repaired, send the "SCPDBG,0" command
and disable debug output.
