I have an HMI where an operator can choose a filename to execute.
The filename is 10 words long, 2 characters per word.
The filename e.g. "PROG1" is selected from the HMI and sent over Modbus to the Festo PLC.
On the Modbus, the filename text "PROG1" seen as 3 words
Word1: Decimal Value = 21072
Word2: Decimal Value = 18255
Word3: Decimal Value = 49
The question is how can I convert a value of any length word(s) from their Decimal Value to the ASCII equivalent string and read it back into a variable ?
From this ...Word1+Word2+Word3 .....How do I get this ----> "PROG1"
Can someone help the newbie ?? Please let me know if more clarification is needed..
thanks

SOLVED : Take 3 WORDS and convert back to the ASCII String that the Words represent
The Words :
Word1- Decimal Value : 21072
Word2- Decimal Value : 18255
Word3- Decimal Value : 49
The 3 Words Converted back to a String = "PROG1".....as seen in the attached picture, (the value for the result variable "sProgramName")
