Route: Batch Barcode Generator - [ How to Use FNC Function Codes ]In the [Edit Barcode] module:
- Click the [Barcode] button on the right side.
- In the pop-up settings page, click [More Settings].
- Check the box next to [Enable FNC Function Codes] to activate the FNC function.
Applicable Barcode Type
This function is only valid for the Code128 type and its extended version, GS1-128.
FNC Function Codes & Replacement Symbols
Currently, the Code128 standard defines four FNC function codes: FNC1, FNC2, FNC3, and FNC4.
After enabling the FNC function, you need to insert the corresponding replacement symbols—{FNC1}, {FNC2}, {FNC3}, and {FNC4}—into the barcode text at the positions where the function codes are required (see the diagram below for reference).
Example Operation
As shown in the diagram above: If you need to insert the FNC1 function code after the number "69", simply add the replacement symbol {FNC1} right after "69". The same operation applies to other FNC function codes (e.g., insert {FNC2} for FNC2, and so on).
