6.7.3 Data conversion rule
Code carrier data formats
The following code-carrier data formats are supported:
●
Data format: Explanation
● ASCII: ASCII character set
● INT: 16-bit integer (Intel format)
Range of values: -32768 <= INT <= +32767
● BCD: Binary-coded decimal number (if necessary, with sign and decimal point)
Non-relevant decades are preassigned the value 0, left-justified.
(Compare <code carrier data format> for Item / BItem)
Assignment between code carrier data and dialog data
Among other things, the conversion rule for Item<n> or BItem<n> includes the assignment to
no/one/multiple dialog variables, where appropriate with a conversion rule, which is
described in more detail in this section.
The general conversion rule for Item<n> or BItem<n> is as follows:
(B)Item<n>=<line>
<n> := consecutive number of code carrier data,
ascending without gaps
<line
>
:= <(max.) length in bytes><code carrier data format>
<dialog variable>
Item1 32 ASCII T1
