The following table shows the inspection results available for an OCR Tool.
The Inspection Result names are used by the Math tool, Communications
Message Editor, and Discrete I/O Editor.
Inspection Result Definition & Usage Field Type
Pass 1 if the OCR Tool passes. 0 if the tool fails. Uword
Warn Always zero. Uword
Fail
Fail code:
0 = PASS
9472 = No binary correlator coprocessor installed
9473 = No font assigned, or font could not be loaded
9474 = No characters present in the font
9475 = Match fail or no characters recognized

String # and Fail # results are only available for a given string if the string’s Mode is not Disabled.
When accessing OCR data using the math tool, strings are converted to numbers. See Accessing OCR Re-
sults from Math Tools in this chapter for details.
If the tool’s fail code is anything other than this, it indicates an error condition in which the tool cannot be pro-
cessed. In this case, Fail 1 through Fail 4 are invalid, and usually set to zero.
