defined in Operand 2 Field on page 292 must be a contstant
defined in the field or retrieved from Industrial Ethernet.
Masked String Compare
If you select Find Substring from the drop-down list, then
the String tool will determine if the string specified in
Find Substring
Operand 1 Field on page 292 is in the string defined in
Operand 2 Field on page 292.
Operand 1 Field
Use the drop-down list in Operand 1 to select the first string for the comparison operation. The options are:
• one or more strings decoded by OCR tools (for example OCR_1, OCR_2, etc.)
• Barcode tools
• CONSTANT
• Industrial Ethernet
Operand 2 Field
Use the drop-down list in Operand 2 to select the first string for the comparison operation. The options depend on what
you select for an Operation Field on page 291. If you select String Compare or Find Substring, then the options are:
• one or more strings decoded by OCR tools (for example OCR_1, OCR_2, etc.)
• Barcode tools
• CONSTANT
• Industrial Ethernet
If you select Masked String Compare, then you must use a CONSTANT value either entered in the field for coming
from Industrial Ethernet. Masked String Compare does so on a positional basis; for example, it looks for characters a
position 1, 2, and 3, and 4, 5, and 6 are ignored because they are masked. Sensor-decoded strings cannot be used
because they can be of variable length.
