Should a packaging machine HMI support multiple languages?
• If operators are multilingual, the HMI must offer EN/CN/local language switching to cut misoperation.
• Confirm at purchase whether PLC/HMI language packs are free and field-editable, avoiding paid unlocks.
• Multilingual HMI must translate alarm texts and recipe names together, or changeover reads wrong parameters.
• For EU export with CE, HMI must include the official language of the country of use, or FAT acceptance stalls.
• Require a language-switch demo at FAT, verifying units and date formats display correctly after switching.
