For sending weight for example 32, 5 kg to printer in ASC II i will send the value But i get the weight in controller from scale in the word its looks like how i can transform the value from word to dword, and in ASC II this is not a question of how to just convert a word to a double word I can't figure out how to transform a word(step7) to a double word (for printer) in ASC II language

ASCII https://en.wikipedia.org/wiki/Ascii ASCII, abbreviated from American Standard Code for Information Interchange, is a character encoding standard for electronic communication. You most probably need to handle the package as an array of CHAR. You will get the ASCII representation when you specify CHAR as a data type. Be aware that such a character is 8-bits in size. So you will need more than one character, therefore more than 8 bits.
