How to convert DINT array to STRING

bernie_carlton · Dec 13, 2010

A common barcode is the Code128, which contains 128 "characters".

This doesn't mean a returned barcode has 128 characters. It just means that it CAN ENCODE all 128 ASCII characters. The returned length is dependent oa the particular symbol and 128 characters seems like an awful lot.

Agreed - I merely quoted as an example - trying to get the point across that the String UDT should be matched to the data length from the scanner being used - 100 DINTs (398 characters) is grossly OTT.

Seems like 100 DINTs was chosen to be OTT certain of being able to hold all the scanner data....

Once hiroT determines the data format from his scanner, he can create his array and String UDT sizes accordingly.

I appriciate for your kindness, daba and barnie.

I misunderstood.
I have thought that STRING data type is useful when data size is less than 82 byte.

As daba explanation,
Always it is good to use STRING data type regardless of data size.
Is it right?

And I have one question.
What is OTT?

OTT = "Over the Top"

"Over-Engineered"
"Wasteful"
"A sledgehammer used to crack a Walnut"

Create your own String data-type to meet the needs of the string data it has to hold.

Thank you.
I understand the meaning of OTT.

STRING data type that is pre-defined by AB is DINT LEN and SINT[82] DATA.

MY_STRING data type that is I defined for matching my needs data size, is INT LEN and SINT[300] DATA
( for example , this situation , barcode data is less than 300 bytes)

data1 is pre-defined
data2 is MY_STRING

Thank you.

You will likely get better response if you start a new thread, then supply all of the information that you have. Like:

- which PLC you are using
- what the DINTs look like. Are the letters mixed up?
- are the contents of the DINTs representing letters, one per 8 bits, or numbers, where you take 8 bits and make 3 characters for the number?
